[Feature] Add fan/ventilation percentage to MQTT itho/ithostatus messages #218

Closed FrankvdAa closed 6 months ago

FrankvdAa commented 6 months ago

At the moment only the Fan setpoint (rpm) and Fan speed (rpm) are in the MQTT status messages, but it would also be nice to see the fan percentage (0-100%).

There's already a Ventilation setpoint (%), so maybe adding Ventilation speed (%)?

I'm able to calculate percentage through itho/state, but that is only sent when speed is changed.

The info available on the MQTT topic is based on available information from within (with 2 exceptions) the itho firmware. Try enabling some of the I2C commands found behind the "System settings" menu of the add-on. I have "Speed status" and "ExhFanSpeed (%)" available which both seem to be % values of the actual fan speed.

Sorry, didn't know that. After enabling Fan system status (31D9) I get the additional Speed status.

Thanks!
