Question

Value Stream doesn't log values through API calls

Hi guys,

 

I'm facing trouble using Value Stream in association with Thing.

Following the guide https://developer.thingworx.com/en/resources/guides/data-storage-methods/dsm-value-streams I'm only able to feed the Value Stream by updating the property through the Composer.

Instead, trying to update the same property with a PUT (as described in API reference) I get a 200 OK HTTP response (infactThing's property is correctly updated) however its corresponding Value Stream's property is not logged.

Please, is there someone who can explain me why?

 

Thank in advance for any suggestion

Alvaro

The value stream should be working, in fact your behavior is like using a remote device to change the binded property, and remote properties can always be logged. 

 

Just check if the property is in logged and persistence status.
