MQTT-Client script stopped sending Units

[gasblaser]

Hi,

I have LM5Lp2 with BluHome-Addon for three FreeAir 100 ventilation devices. I used the Client-Script https://kb.logicmachine.net/integration/mqtt-client/, my configuration as attachement. Initially, MQTT sent units with the measurements, but since some days units are missing. I would like to have the units send again, what have I to do? Thanks!

Modified example that will publish value + units:

Code:

Thanks for the quick reply. I changed the script an restarted it. Now the broker gets no data at all, the log shows:

* arg: 1
  * string: mqtt connect status
* arg: 2
  * bool: true
* arg: 3
  * number: 0
* arg: 4
  * string: connection accepted
* arg: 5
  * number: 0
* arg: 6
  * nil

Did I forget anything?

Values are published only on change. Change any object with mqtt-control tag and the new value will be published.
