Thing property values became empty and quality is showing unknown.

Thing properties became empty when I'm checking property vtq, it's showing unknown.

These properties are updating from last two weeks but from yesterday it's showing empty values.

Why values are getting empty and why the property quality is unknown?

On what basis property quality is calculated? Did anyone faced this issue? 

Can anyone help me with this issue?

 

Thanks,

Abhiram Kuncham

Did the Thing become disconnected or did you change the model and the values become null?

Thank you for your response PaiChung.

No, thing is having properties which inherit from thingshape and some of those properties are binded to remote thing. Properties which are binded are having proper values remaining property values became empty.

Model and all remains same, nothing was changed.

when I check property vtq, quality of some properties are showing UNKNOWN.

What is this unknown means and how the quality is checked.

Usually Unknown means the value is null, not received/outdated, or never set.

okay, any idea how existing values become null and are there any scenarios will cause this issue?

is the property you are looking at (which became null) Persisted ? if they dont have their aspect set as persisted then it will become null or initialized to their base data type when Thing restarts. Check those property definition on your thingshape and see if that solves your problem

okay. From your response it wasn't clear if the issue still exists or it got resolved after you changed to persisted ? can you confirm that ?

All properties were persisted before only, I don't think persisting properties was the issue.

 

Thanks,

It's in Thingworx 7.2.11 b17.

Some properties are bound to remote thing some are generic properties.
