Hi
I have a problem with Dimmer updated by “sensor” rotary encoder from Mysensors gateway.

Project:
The Rotary encoder updates the dimmer by a value in the domoticz, then by the script or group other dimmers are updated with the same value (rotary encoder).

What works:
Dimmer is successfully updated by (sensor) mysensors gateway, I see visually that value bar is moving and setup on correct value, but…

Does not works:
...that's it, nothing changes on other dimmers, like rotary was set up with value but not trigger, no actions are made. In the dimmer log tab, I can see when dimmer from the dashboard is setup (set up: specific value ) and linked dimmers are updated too, but when the main dimmer is updated by rotary encoder there is only “ON’ word and linked dimmers do not receive any data.

This is a bug? Wrong Arduino script? Or do I have to do additional actions in domoticz? :?
