Question

Setting property of a thing with value, time stamp and quality

I have different properties for several things which have a value, time stamp and quality. The value should be logged and I should be able to add an alert level. What is the best way to set up these properties?

Steven, what type of properties would they be? If the properties are going to be the same on multiple Things, you can set them on a ThingTemplate level or branch out to ThingShape levels, it would depend on your use case. Can you expand on your use case as well?

Hey,

I have added them on a ThingShape level so I can easily add them to different things. I'm actually looking for a property basetype like a VTQ where besides the value, I can also set the timestamp and quality.

I think I found a solution requiring a bit more properties but it is manageable. I also found that it also better to use a Stream in stead of a streamValue because then I can use my timestamp in stead of the system time. But when I run my code a couple of times, only a random amount of stream values are actually added.

Just so I understand, you run code to add/ update stream entries but not all entries are getting added/ updated?
