pwm: 0 and invert_heater (NO valves)

[ZdenekM]

Hi,

I have normally open valves on my radiators, controlled by light dimmers so I'm using invert_heater: true, which used to work with on/off regulation. Now I tried to switch to pwm: 0 but it seems that the invert_heater: true gets ignored in this case. Is that so? Is it a bug, or it is not supposed to work like that?

I have a similar problem, did you manage to find a solution? @ZdenekM

Unfortunately, no, so I stuck to on/off control.

That's not possible for thé moment.
May you need to have 0 for opening valve and 100 to close it, you may use an input number like input_number.thermostat_output as heater entity receiving the output of the thermostat, and use an automation to take this value and compute the new value to be applied to the valve:

{{ abs(100 - (states("input_number.thermostat_output") | float(0))) }}

If it work, I'll add it to the code.
