Hi, I'd like to ask your advice. My situation is as follows:
I have a hot water tank - in it a thermometer and a heating coil. The heating coil is connected via Shelly to the HA. In the HA I have created a "Generic thermostat" from this thermometer and a switch from Shelly.
But the problem is that the Generic Thermostat apparently doesn't have the ability to control the HVAC action attribute of an entity (such as the MQTT thermostat). When the thermostat is on, it is always heating.
My spiral has "its own built-in logic (based on its own thermometer)", so not always when Shelly is on (Thermostat ON --> HVAC-Action = Heating) there is actually heating.
Is it possible to somehow adjust the HVAC-action based on e.g. the measured power input of the spiral (I have this available).
So turning on the thermostat would turn on the switch (Shelly --> spiral), the entity state would be heat, but the hvac_action would be idle until the power was e.g. > 20W? And then hvac_action will be heating.
A shortcut to make the hvac_action attribute be heating only if heating is actually occurring.
I couldn't find anything like that..
Thanks a lot!
