Hi all

 

I'm create a Things based on MQTT Subcriber  and connect to MQTT broker. i'm using subcription on this Things with datachange events. 
When i'm change properties value with mqtt broker, the subcription is not triggered.  But when i'm use UI change value, the subcription still work.
I'm changed Properties Data Change Type from Value to Alway. And  I have set visibility to ThingworxPeristentProvider for System User by reading similar topics but the situation is not changed.

 

P/S: I'm create a Things based on MQTT (combine connection and subcriber), it's still work.


Please support me, thanks.

    Yep, i already read and do same way. But i can't find document for Subcription MQTT.  The problem is Subcription still work with MQTT type, but don't work with MQTT Subcriber
