OK, in that case in order to have the UI update and the Rule triggered, you need to publish to both topics from your main OH. To do that you need one Channel with the stat Channel configured for the commandTopic and another Channel with the cmd topic configured for the commandTopic. Have one of them subscribed to the stat topic as well. Then link both Channels to the same Item but link the Channel that is not subscribed to the stat topic second and set up a follow profile. This will forward any command you send to both Channels and therefore to both topics. That should update the LCD and trigger the Rule.

Finally I could test this. I added:

In Paper UI

Channel HeatingMode
MQTT State topic: hestia/local/stat/heatingmode
MQTT Command topic: hestia/local/cmnd/heatingmode

Channel HeatingModeFollow
MQTT Command topic: hestia/local/stat/heatingmode

In .things file

String HeatingMode { channel="mqtt:topic:21501fcc:heatingmode", autoupdate="true", channel="mqtt:topic:21501fcc:heatingmodefollow" [profile="follow"] }

After saving, I click in the UI (a desktop one) OFF, it works, but when I select Auto ON back, it starts switching endless in the main OH between ON and OFF

Anyway, if I change the channels:

Channel HeatingMode
MQTT State topic: hestia/local/stat/heatingmode
MQTT Command topic: hestia/local/stat/heatingmode

Channel HeatingModeFollow
MQTT Command topic: hestia/local/cmnd/heatingmode

This configuration seems to work in all the cases but one: if I change HeatingMode in HestiaPi’s OH, the main OH does not get updated. This is because in that case, the change is published to hestia/local/cmnd/heatingmode, but hestia/local/stat/heatingmode does not get updated

I am wondering, wouldn’t be easier to use one channel only?
