MQTT things property cannot trigger subcription

Hi all,
I am using MQTT extension 3.0 to connect to my MQTT broker. When thing receives messages on the right topic, its properties can change but subscription for that data change is not triggered. I tried to change data by Composer UI then the subscription is triggered. I have set visibility to ThingworxPeristentProvider for System User by reading similar topics but the situation is not changed
Can someone help me?
Thanks

Hi @QU_9823297.

 

Make sure your subscription is enabled.  Also, have you checked the script logs for any errors?

 

Regards.

Re: MQTT things property cannot trigger subcription

I believe that if the property change happens via the MQTT Extension (ThingWorx 9.1), the DataChange event not raised.

 

If this is the case I would consider that a bug. I also think I have filed it a while ago.

 

Please open a ticket with Tech Support.
