Hello @kremer ,

 

Thank you for posting to the PTC Community.

 

Can you kindly provide what version of ThingWorx Platform and ThingWorx Analytics you are using, so that we may better understand your problem?

 

Regards,

Re: Error in getting matching Analysis Events

Hey Neel,

I use the hosted evaluation server, so the version for both is 8.4. More Information: I send data via MQTT to the platform. The MQTT message is a json object, so I map the data with a subscription into another thing. The analysis event listen to one of the datachange events and the result is the error message.

@kremer ,

 

Thank you for providing that additional information.

 

Have you had the opportunity to review the HelpCenter Guide on Implementing Anomaly Detection?

 

When we see issues around SENSORVALUE!, it is usually due to configuration issues.

 

Please let me know if the guide helps resolve your issue.

Re: Error in getting matching Analysis Events

The tutorial helps me not, the sensorvalue is like a fliflop. Everytime the value changes the analysis event should run. The problem is, I change the value through a subscription and this causes the error. Is there any solution to trigger an analysis event with an property that changed through an subscription?

@kremer ,

 

Sorry for the delay, as I was Out Of Office this past week.

 

At this time, there is no method to trigger and Analysis Event with a property that changed though a subscription.

 

You could try updating the property and create an alert based off of the property.
