IoT Tips

  Meet Chris. Chris leads the ThingWorx Flow portfolio, which will be releasing in 8.4. Chris has “a long history with workflow and a lot of interest in it.” He was originally hired as a product manager by Jim Heppelmann [PTC’s CEO] about 20 years ago to build a workflow engine for Windchill, our PLM solution. As a matter of fact, this feature is still a part of Windchill today. Pretty neat, right? We were able to leverage Chris’ workflow expertise and experience to create ThingWorx Flow. Check out more below.   Kaya: Why did we create ThingWorx Flow? What challenge does it solve? Chris: In order for customers to realize the full business value for connected solutions, it typically isn’t enough to just surface an alert to show a dashboard of health. Customers want to automatically do things like create service tickets or automatically order consumables as they run low. To do that—to realize that automated value—you need a couple of things. First, you need to be able to easily connect to enterprise systems (like SAP, Salesforce or Microsoft Dynamics) to create service cases. Second, you need to be able to define and execute your business process logic.   Kaya: Can you give me an example? Chris: Definitely. The business process may involve the need to replace a filter based on a contamination alert. After I receive the alert, I need to look up in the bill of materials to find out which filter is applicable to that particular device or product; if it’s not in stock onsite, I need to order it. When it arrives, I then need to schedule the service, knowing that it’s going to be there at a particular time, which entails working with another service system like Salesforce.   So, you have a number of these different enterprise systems that you need to connect to, and you need to support that orchestrated business process to realize the value of a fully automated flow. That’s what has really led us to do it—because, again, the compelling business value in these connected device solutions is often around an automated approach to service or maintenance issues. The value is compelling because automated processes minimize delays, support business growth and scale without hiring as many additional people and eliminate human errors and variability that lead to improved quality at lower costs or stronger margins. Sample ThingWorx Orchestrate Workflow: Send RFQ to Supplier and Add Part to List If State ChangesKaya: So, who ultimately benefits from Flow? Chris: The benefits are realized by an organization as a whole in terms of increased responsiveness, flexibility, reduced costs and higher availability. The ThingWorx solution is unique in that it allows an organization to quickly realize these benefits by optimizing the participation of several key roles. As a result, no role becomes a bottleneck to addressing an urgent business need.   In addition to developers, the many business analysts across the organization are now empowered to define and modify their business processes themselves through Flow. They do this by using the system connections (or subflows) created by their system experts and ThingWorx models that were defined by developers. All of this work is achieved using our visual modeling tool without the need for extensive training.   The system experts can define portions of flows or subflows that get, create or edit information in the systems they understand most within the Flow editor. This enables each role to focus on using their most valuable skills and ultimately eliminates the bottlenecks that cause reduction in business responsiveness when everything must be done by a few highly-specialized experts. Now, developers can leverage the outputs of flows to drive behavior in the application and visualize key KPIs and overall health.   Kaya: So, I see that we’re not only connecting business systems, but we’re also connecting people. We enable them to leverage each other’s different perspectives and areas of expertise. I know we gave developers a sneak peek of ThingWorx Flow in one of our latest posts. Do you have a more detailed demo that we could share this week? Chris: Sure thing. Check this out. (view in My Videos)   Kaya: Wow! I can definitely see how Flow saves immense time in workflow creation. Now, final question: what is your favorite aspect about working at PTC? Chris: The most interesting thing to me is that I get to work with so many different customers in so many different verticals that have such a diverse set of challenging and interesting problems. It’s fun to work together with these customers for us to understand their problems, their unique environments and then to, with them, build solutions using a combination of our products and their existing systems and tooling—that’s what I think is most fascinating.   I learn something new about the way things are made, manufactured, built and serviced every day, and it just makes my life much more interesting. I don’t feel like I’m doing the same thing every day. Working with customers to understand and address their challenges and help them realize their business goals is really rewarding and, again, the diversity of those requests is what makes the job particularly interesting and fascinating.

  Meet Anthony. Anthony came to PTC from a large industrial company as a user of Axeda, a leading device connectivity company that PTC acquired in 2014. With a background in aerospace engineering and experience in a variety of industries including life safety, healthcare, nuclear power, and oil and gas, Anthony has been working to create new value around innovation for customers transitioning to ThingWorx. When he’s not working on IIoT, he’s playing music on Cape Cod, photographing Hawaiian landscapes or bringing awesome inflatable chairs into the office.    You may recall from last week's post that Thing Presence is one of the top three features in 8.4 that you might not know about. This week, I spoke with Anthony for a deeper dive on Thing Presence. Check out how it went.   Kaya: What was the challenge users were facing that led us to create Thing Presence? Anthony: Axeda customers transitioning to ThingWorx were struggling with the connectivity use case and kept asking, ‘why is my asset always offline?’ When we evaluated it, we discovered that it was tied to the difference between AlwaysOn and Axeda eMessage protocol architectures. IsConnected will always report false for polling and duty cycle devices.   The use case of Thing Presence is to know that the asset is reporting into the network and is ready to provide information (push) or be accessed to retrieve information or do a remote desktop support (pull). This use case is relevant for any asset in ThingWorx that uses duty cycle.   In ThingWorx 8.4 (coming in early 2019), the new IsReporting state will inform the user when a polling device is communicating on a regular basis. If it is, then IsReporting will be true. The IsReporting state resolves the discrepancy wherein devices that are on duty cycle appear disconnected due to the IsConnected state reporting false.  New "IsReporting" state improves visibility of an asset's communication state Kaya: How exactly does Thing Presence work? Anthony: You can think of it in terms of having teenagers. You tell them they need to check in with you on a regular basis through text message. If a text is missed, all of a sudden you take action.   Now, imagine the teenager is a device. If a device was supposed to check in every five minutes and it misses one poll, I want to flag that as a problem. The challenge with that from a service perspective is that sometimes your service personnel will go out and work on a device and may need to take it offline for a bit of time; we need to factor that in. We certainly don’t want to deploy someone or try to fix something when a service technician is already there.   You might decide, ‘my average service visit is an hour, so, if I miss a couple of pings, I’m okay; but, if I’m offline for more than an hour, then I’d like to know about it because I’d like to take action.’ Thing Presence allows you to define that window.   Kaya: You’ve mentioned ‘duty cycle’ and ‘polling cycle.’ Can you explain these terms? Anthony: Duty cycle and polling cycle are the same thing. It means that a device has a time for which it is expected to check in, and, provided that it checks in within that timeframe, all is good with the connection.   Connected services rely on a connection. As soon as the connection is broken, I no longer have the ability to service the asset.   Kaya: Given everything we’ve discussed, where do you see Thing Presence headed? Anthony: The next piece of the equation for us is to provide information on the health of the connection. When you look at servicing a remote asset, you need to a) know that it is communicating, and b) know that the connection is healthy before you try anything. I wouldn’t want to try a software update if I am losing connection with my asset on a regular basis.   What do we mean by health? We mean: is the device checking in when it should be? If it’s not, is there a pattern to that connection, and are those patterns tied to applications? For example, is it only on during working hours? Does it turn off during holidays? If the device is in a school, does it turn off during summer maintenance work? This allows us to garner insights on how and when the equipment is being used, not just operating status. At the end of the day, does this mean I can apply analytics and AI tools to it? Absolutely. Is it the first place I would apply it? Probably not.   Kaya: In your mind, what is the next big thing coming in ThingWorx that you’re particularly excited about? Anthony: Mashup 2.0 and Asset Advisor 8.4. (Double mic drop.)   Kaya: That’s awesome. My last question is related to you. Can you tell me what your favorite aspect is about working at PTC? Anthony: The chaos. Very often it’s chaos that breeds innovation. What I mean by that is that, if you try to create something because you sit down and you say, ‘I am going to innovate,’ very often that is a failure because the majority of the time it’s the influence of a deadline, a customer need or an application at hand that makes the environment trying and sometimes hectic. But, it is in these challenging environments where you can be the most creative and innovative as an engineer.

  If you’ve ever wished you could see into the future, you’ve come to the right place! Put your reflective suits and sunglasses on to prepare for a glimpse into the future of our upcoming ThingWorx 8.4 release! Here are sneak peeks of the top three features you may not have known are coming in ThingWorx 8.4.   1. Thing Presence While it sounds like something from an episode of Ghost Hunters, Thing Presence provides insight into the communication state of polling or duty cycle Things (those that check in and out on a periodic basis). We’re introducing a new IsReporting state, which would be set to true when polling assets check in on time and are considered “present in the network.” This helps to bridge the gap where the traditional ThingWorx IsConnected state reports offline and does not coincide with the actual network presence of the device.   Thing Presence: New "IsReporting" State2. Data Helpers You may not know what Data Helpers are, but if you’re a longstanding ThingWorx developer you likely know about Expression and Validator widgets. These widgets were handy because they allowed you to write conditional logic or input validation to drive behaviors in the UI, but were super frustrating to use. They took up lots of room on the visual layout canvas and only had a very little textbox to edit them. In the 8.4 release, we are happy to announce that these two widgets will no longer be placed on the layout canvas. Instead, they will have a dedicated editor to work from with plenty of room for code development, parameter configuration and event definition and binding. We’re wrapping all of this functionality into a nice little feature called…Data Helpers. Data Helpers: Expression and Validator Widgets No Longer in Layout Canvas3. ThingWorx Flow In case Thing Presence and Data Helpers aren’t exciting enough, we’re also introducing ThingWorx Flow, a neat new feature set that dramatically speeds development of connected applications through integrations with business systems like Salesforce and SAP. Imagine that, when a certain alert triggers, you want to automatically create a Salesforce service ticket and even send an emergency text to an operator to prevent damage to a device. A large set of out-of-the-box system connectors (PTC Windchill, Office 365, Google Docs, Slack, Jira and more) are included, which you can drag and drop onto a canvas to visually define a workflow. In the example below, a ThingWorx-connected device element, a Salesforce “create case” action and a Twilio text message connector were dropped into the canvas to create a visual workflow. Orchestration: Example Workflow that Creates Salesforce Cases and Alerts OperatorsThing Presence, Data Helpers & Flow—get ready for these and more in ThingWorx 8.4!   Stay tuned for future posts that go into greater depth about each of these features and comment your thoughts below!   Stay connected, Kaya

Exciting news! ThingWorx now has improved support for Docker containers to help you manage CI/CD, improve development efficiency in your organization and save costs. Check out these FAQs below and, as always, reach out to me if you have any additional questions.   Stay connected, Kaya   FAQs: ThingWorx Docker Containers   What are Docker Containers? From Docker.com: “a Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings”. Learn more here.   What's the difference between Docker containers and VMs? Containers are an abstraction at the app layer that packages code and dependencies together, whereas Virtual Machines (VMs) are an abstraction of physical hardware turning one server into many servers. Here are some great discussions on it on Stack Overflow. Containers vs. VMs   How can I build ThingWorx Docker images? Check out the Building ThingWorx 8.3 Docker Images Guide or watch this video to instruct you on how to build and test Docker containers. (view in My Videos)   How does PTC support building ThingWorx Docker images? PTC provides the ability for customers and partners to build ThingWorx Docker images. A customer can download the Dockerfiles and scripts packaged as a zip folder from the PTC Software Downloads Portal under “ThingWorx Platform,” then “Release 8.3”  then“ThingWorx Dockerfiles.” (Please note that you must be logged in for the link to function properly.) PTC Software Downloads PortalThe zip folder contains the Dockerfiles, template jar, and scripts to fetch Tomcat, and ThingWorx WAR files using CLI. Java must be downloaded manually from the vendor's website. We also provide an instructional guide called “Build ThingWorx Docker Images” available on the Reference Documents page on the Support Portal.   How are ThingWorx Docker images different from the usual delivery media of WAR files? The WAR file delivery is typically accompanied by an installation guide that contains the manual steps for creating the VM or bare-metal environment. That guide includes instructions for the administrator to manually install the prerequisites, including Tomcat, Java, and ThingWorx platform settings files. To deploy and run the WAR file, the administrator follows the guide to create the runtime environment on an OS. In contrast, the Dockerfile build in this delivery automates the creation of a Docker image once supplied with the prerequisites.   Do you have any reference deployment and guidance? Yes, you can refer to our blog post to learn how to deploy and run ThingWorx Docker containers on your existing Kubernetes environment.   Is there any recommendation on which Container Orchestrator as a Service (CaaS) a customer should run ThingWorx Foundation Docker container images on? You can use Docker-Compose for testing, but it is generally not suggested for production deployment use cases. In a production environment, customers should use container orchestrators such as Kubernetes, OpenShift, Azure Kubernetes Service (AKS), or Amazon Elastic Container Service for Kubernetes (Amazon EKS), to deploy and manage ThingWorx Docker images.   What are the skill sets required? Familiarity with OS CLI and Docker tools is required to build building the ThingWorx Docker images. Familiarity with Docker-compose to run the resulting Docker containers is needed to test the resulting builds. We don’t recommend Docker-Compose for production use, but when using it for local testing and demo purposes, users can rapidly install ThingWorx and get it up and running in minutes. We expect PTC partners and customers who want to run ThingWorx containerized instances in their production environment to possess the required skill sets within their DevOps team.   How is ThingWorx licensing handled with the Docker images? By default, the container created from these Docker images starts up in a limited mode with no license supplied. You can configure your username and password for the PTC licensing portal to automatically load a license via environment variables passed into the container on startup. Additionally, you can mount a volume to the /ThingworxPlatform directory, which contains your license file, or to retrieve a license request. To keep your Host ID consistent, ensure that the /ThingworxStorage and /ThingworxPlatform directories are persisted and not removed with individual container restarts. More detailed instructions can be found in the build guide or in a Kubernetes blog post .   Is Docker free? What version of Docker does PTC support for ThingWorx? Docker is open-source and licensed under the Apache 2 license. Information on Docker licensing can be found here. The following Docker versions are required: Docker Community Edition (docker-ce) Version 18.05.0-ce is recommended. To install the Docker Community Edition on your system, follow the instructions for your operating system on the Docker website here. Docker Compose (docker-compose) Version 1.17.1 is recommended. To install the Docker Compose on your system, follow the instructions for your operating system on the Docker website here. What persistence providers are currently supported? PTC provides the ability to build ThingWorx Foundation containers for the following supported persistence providers: H2 Microsoft SQL Server PostgreSQL Additional persistence providers will be added to the Docker build delivery as the ThingWorx Foundation Platform releases support for those new databases in future releases.   What are some of the security best practices? For production use, customers are strongly advised to secure their Docker environments by following all the recommendations provided by Docker. Review and implement the best practices detailed at https://docs.docker.com/engine/security/security/.   Can we build Docker images for ThingWorx High Availability (HA) architecture? Yes. ThingWorx Dockerfiles are provided for both basic ThingWorx deployment architecture and HA ThingWorx deployment architecture.   How easy is the rehosting and upgrading of ThingWorx releases on Docker with existing data? In Kubernetes environment, data is kept in a separate volume and can be attached to different containers. When one container dies, the data can be attached to a different container and the container should start without issue. For more information, please refer to the upgrade section of the Building ThingWorx 8.3 Docker Images Guide.   Is it okay to use the Docker exec and access the bash shell to make config changes or should I always rebuild the image and re-deploy?­ Although using Docker exec to gain access to the container internals is useful for testing and troubleshooting issues, any changes made will not be saved after a container is stopped. To configure a container's environment, variables are passed in during the start process. This can be done with Docker start commands, using compose files with environment variables defined, or with helm charts. More detailed instructions can be found in the build guide or in this blog post .   What if there are issues? Should I call PTC Technical Support? We are providing the scripts and reference documents solely to empower our community to build ThingWorx Docker images. We believe that customers using Docker in their production processes would have expertise to manage running Docker containers themselves. If there are any issues or questions regarding the build scripts provided in the PTC official downloads portal, then customers can contact PTC Technical Support at 1-800-477-6435 or visit us online at: http://support.ptc.com. PTC does not provide support for orchestration troubleshooting.   What can you share about future roadmap plans? As we are enabling our customers and partners to build ThingWorx Foundation Platform Docker images, we plan to do the same for upcoming products such as ThingWorx Integration & Orchestration, ThingWorx Analytics, upcoming persistence providers such as InfluxDB, and many more. We also plan to provide additional reference architecture examples and use cases to help developers understand how to use Docker containers in their DevOps and production environments.   Where can I learn more about Docker containers and container orchestrators? See these resources below for additional information: https://training.docker.com/ https://kubernetes.io/docs/tutorials/online-training/overview/

If your mashups are feeling cramped and crowded, we’ve got some good news for you. Coming in our next release, ThingWorx will offer truly responsive layouts for your mashups, allowing you to adjust the size of your viewport or present a mashup on a variety of displays—laptop, tablet, phone, etc.—without compromising presentation or responsiveness. This new layout capability is based on Flexbox. Check out this article to learn more.   Here’s a sneak peek of our new layout editor. It’s still in development, but I hope you can start to see how you can use this in your UI development.   Sneak Peek: Responsive Mashup Layout Notice the ability to split the layout into containers. Each of the containers allows you to horizontally or vertically layout, distribute from left or right, align from top or bottom, justify space between widgets, etc. This gives you as the developer ultimate control to define the responsiveness of the mashup.   Like what you see? Any feedback? Let me know below!   Stay connected, Kaya

Disclaimer: Please note that, while the ThingWorx Git Backup Extension is a very useful tool, it is not a PTC product, nor is it supported by PTC.   Hi ThingWorx users,   Trying to manage your ThingWorx application artifacts in a CI process? Wondering who changed that line of code in your Thing Service? Trying to see what your Mashup looked like last release? Time to Git excited! Introducing the Git Backup Extension, an open-source tool available here to offer a stronger integration with the Git source repository. This Git feature can push or pull code and artifacts (like entities, data exports or extension dependencies) to your Git repository.   Here are some highlights of how this works within ThingWorx:   First, configure your Git repo to work with ThingWorx by creating a Git Backup Thing. Then, simply open your new Thing, navigate to the Configuration editor and enter information like your Git URL, your Git username and password, your repo and branch names, etc. See example below. Configuring your Git repoWith this configuration in place, you can now use the Home Mashup of this new Git thing to browse the repository and pull down contents to your local ThingWorx instance. For new projects, you can also push new entities to the repo as you work on your application.   As you and your team are working, you’ll want to see the differences of the files you are editing and working on collaboratively. The Git extension feature makes this easy. Just like you can see diffs clearly delineated for a file with your Git client, you can see the same with this Git integration in ThingWorx. Similar to the git status command, the Git ThingWorx extension will show you the list of files you have changed that are available to push, as well as their diffs. See an example below. Checking the Git status While working, if you want to switch branches or pull down a new project, you can check out a specific version and see all commits available on that branch (see below). Checking out a specific commit Want to learn more or try it for yourself? Find the open-source Git Backup Extension here and check out the Git Backup Extension User Guide for guidance.   Stay connected, Kaya   P.S. What do you think? Comment your thoughts below!

Meet Neal. When Neal joined PTC five years ago, he immediately hit the ground running on IoT initiatives, working in multiple areas ranging from pre-sales to partner relations. Today, he is a Worldwide ThingWorx Center of Excellence Principal Lead at PTC, and his biggest focus is supporting the go-to-market for the Microsoft partnership.   I sat down with Neal recently to hear the details on exactly how Azure and ThingWorx can be used to develop world-class IIoT applications.   Kaya: Can you explain how Azure and ThingWorx work together? Neal: Yes, so Azure provides the cloud infrastructure that our customers need in order to deploy ThingWorx.   By having Azure as our preferred cloud platform, we’re able to specialize our R&D efforts into utilizing functionality that is available in Azure, rather than having to reinvent the wheel ourselves for each cloud platform in the attempt to remain cloud-agnostic. By leveraging a single, already quite powerful, cloud platform through Azure, we’re able to maximize our development efforts.   Kaya: What was the major problem that led to us investigating cloud options? Neal: There were two issues that our users had. The first was we often had complicated installs and setup procedures because we were genericizing the whole process, so the initial setup and run was complicated and expensive. For example, we were requiring them to setup additional VMs and components, and we were giving them generic instructions because we were being very agnostic, when they had already chosen outside of us to use one of the cloud platforms. We knew our customers wanted to move fast, so we had to make it easier and faster for them to see results.   The other issue we ran into with customers was the confusion in the offerings. For ThingWorx, ingest is just one aspect of IoT. ThingWorx is particularly strong in areas like enabling mixed reality and augmented reality as well as application enablement. And, while we also have the ability to perform ingest capabilities, Microsoft is especially powerful when it comes to ingest capabilities and security. We decided that the smartest solution was to leverage Microsoft’s expertise in data ingestion to make ThingWorx even more powerful; so, we made the Azure IoT Hub Connector. By partnering with Microsoft, we have joint architecture where you can see how Microsoft provides key features and ThingWorx will run on top of those features and get you faster to the market to develop the application.   Below is an example of a high-availability deployment of ThingWorx on Azure that utilizes ThingWorx Azure IoT Connectors to access an Azure IoT Hub.  High-Availability Deployment of ThingWorx on Azure Kaya: Why did we partner with Azure? What specific benefits does Azure offer over other cloud services providers? Neal: When we started to look at what our customers were using for cloud services, we noticed that a lot were using Microsoft. When we join forces with Microsoft, we have a much more wholistic offering around digital transformation. With the partnership, PTC and Microsoft are able to leverage each partner’s respective strengths to provide even more powerful IIoT solutions. You have Windchill and Microsoft’s business application strategies; you have Vuforia and Microsoft’s mixed reality and augmented reality strategies; and, you have ThingWorx on the Microsoft Azure cloud. Overall, you have a much more complete and powerful offering together.   Kaya: What is your favorite aspect about working at PTC? Neal: The growth. There’s been a lot of changes over the last five years that I’ve been here. PTC has been able to leverage its strengths and long-time experience in the CAD and PLM markets to enter and ultimately become a leader in the IIoT market, according to reports by research firms like Gartner and Forrester. In short, the growing IIoT market and PTC’s leadership in the industry.   Note to Readers: You’ve likely heard about our major strategic partnership with Microsoft to leverage our respective IIoT and cloud technologies to optimize the creation, deployment, management and overall use of your IIoT applications. If you haven’t heard about the partnership, check out the press release here. If you’re curious about more aspects of PTC’s partnership with Microsoft, check out this site devoted to sharing how ThingWorx and Azure are better together.

Just like the perfect sandwich, we know that you have specific preferences and requirements for your ThingWorx deployment. Whether you like to keep things simple with a classic grilled cheese or you like to spice things up with a more elaborate chipotle mayo BLT, we’ve got you covered. Our ThingWorx Deployment Architecture Guide explains what you’ll need to deploy ThingWorx in three different scenarios: production, enterprise and high-availability (pictured below).   Deployment Architecture for ThingWorx on Azure in High-Availability We’ve recently published Version 1.1 of the ThingWorx Deployment Architecture Guide. In it, you can find updated deployment architecture diagrams to more distinctly show the data and application layers within a ThingWorx environment. Our team has also added a new section on what you’ll need to deploy ThingWorx on Microsoft Azure, PTC’s preferred cloud platform.   Check it out here or in the attachment section on the right.   Stay connected, Kaya

Hi, ThingWorx users! We’re excited to share that we have partnered with InfluxData to make time series analysis in ThingWorx even easier. InfluxDB is a database by InfluxData that is “built specifically for metrics and events that empower developers to build next-generation IIoT, analytics and monitoring applications.”   Why InfluxData?  Today, application developers expect robust querying capabilities, fast response time, easy ways of aggregating and pivoting on data and leveraging results for reporting and visualization. IT and devops administrators also expect cost-effective storage and easy ways of aging data through archiving and the ability to keep large amounts of historical data to satisfy analysis requirements.   That’s why we’ve partnered with InfluxData to make it easier for developers to store, analyze and act on IIoT data in real-time. With InfluxData, developers can build connected IIoT applications more quickly while still incorporating the following capabilities: monitoring real-time alerting predictive maintenance streaming data anomaly and event detection visual and report-based analysis   We considered a few technologies for the purpose of improving ThingWorx time series analysis. Here are a few reasons we chose InfluxData: high compression of data ~45x ability to handle millions of writes per second* ability to read around thousands of rows in milliseconds* supports the standard time series functions of sampling, interpolation, time bucketing, aggregation, selector, transformation, predictor, etc.  * Query and write times will vary based on an individual ThingWorx application’s implementation with Influx. For example, as the number of concurrent reads increases, the query speed decreases. With the upcoming 8.4 release, the ThingWorx Sizing Guide will be updated to reflect representative performance for ThingWorx developers.   In addition to improved query capability, ThingWorx time series with Influx can now use less memory and CPU, giving your platform servers a bit of a break.   To start strategizing on how InfluxData can help you in your ThingWorx journey, here is a sneak preview of what it will look like:   New Features The new ThingWorx Influx Persistence Provider will make query services like ValueStream Thing QueryPropertyHistory, Stream Thing QueryStreamData and QueryStreamEntries even better. Simply create a new instance of the persistence provider, configure it to use your InfluxDB instance, create a new value stream (or stream) from the new persistence provider, and you’ll be writing, reading and analyzing your time series data like never before.   We’re also introducing a new enhancement to improve InfoTable support with time series data, including providing the ability to use a driver property. The driver property can be specified with the QueryPropertyHistoryWithDriverProperty service for time alignment and filling backward/forward in your stream queries.   Let’s walk through a driver property example where you have the properties of temperature, speed and battery level. Timestamp Temperature Speed Battery Level 1480589076592000000 80.003 5012 79 1480589077537000000 80.010 5011 79 1480589077550000000 80.010 5009 79 1480589077562000000 80.030 5011 78   Let’s say temperature is the key driver for your analysis. In other words, you are not concerned if speed or battery level changes—you only care about when temperature changes. We can specify temperature to be the driver property for that particular time and only return stream values for temperature, speed and battery level when temperature changes. If speed or battery level changes (but temperature does not change), the rows associated with those changes would not be included in the results set because neither speed nor battery level is a driver property. See chart below.  Timestamp Temperature (driver) Speed Battery Level 1480589076592000000 80.003 5012 79 1480589077537000000 80.010 5011 79 1480589077562000000 80.030 5011 78  Note that only three of the four rows are returned above because one entry in the original table did not have a change in temperature.    Stay Tuned Look out for these time series improvements and InfluxData integration in our upcoming 8.4 release. I’ll be sure to keep you updated on additional new features coming in our next release (like Orchestration and Mashup Builder 2.0), so check back shortly or subscribe to this Community so we can stay in touch.
