[Mill] Setting heater power level

I’m currently using the Mill integration, and it works pretty well.

However, the only feature i seem to be missing is being able to set power-levels of my gen3 heater itself.

According to the app (and from the buttons on the device itself) I can set three heat-levels; Low, Mid, and High.

I’d like to be able to set these via a service for the mill integration, so I can possibly adjust the heater level programmatically or myself from home assistant, so I don’t need to go back and forth to the app to do it.

(One such integration is to have the heater go into different power level modes depending on how far behind the current sensed temperature is compared to the desired temperature)

I have the same problem with a 1000w mill heater gen3. I can turn on/off and set the temperature of the electric heater but, it’s no possible to set the signal control to fix the maximum power (eg. Signal c. 60% = 600w max). In mill app is possible and it will be a good thing to have in homeassistant.
I run a homeassistant supervised 2024.1.3.
Thanks.

Indeed it would be nice it this API feature could be added to the Mill integration:

@Danielhiversen Is this something that can be picked up or do you need additional help for this feature?
