Can't get Versatile Thermostat to work on my AC

[JochenV1976]

I'm afraid I can't get it to work.

Let me try to sketch it out.

• I'm using an LG air conditioner as a heating source
• A Shelly BLU HT as a sensor in the room
• A Versatile Thermostat that uses over_climate
  And that's how I get overshoot, or I don't get warm enough.

If I understand the "Use internal temperature of the underlying" option correctly, it should set the air conditioner to a setting based on the internal temperature of the air conditioner?
But by enabling this option, I get a serious overshoot, up to 1.7°C.
If I disable this feature, then it don't get warm enough.

Another strange thing:
When the set temperature is 20°C, and the temperature in the room is 17,9°C, shouldn't it start to heat?

And why does the AC start in cooling mode if I toggle the versatile thermostat? The airco was heating when I toggled it to off, so I would expect that a new toggle should start with heating again?

Can anyone point me in the right direction? Or share his working settings?

I maybe also have to mention that is have set the "self-regulation" to light....

Hello

Yes this option is very often a bad idea. The internal is too wrong to be usable.

The only think that will work is to use the "self-regulation" as describe here: https://github.com/jmcollin78/versatile_thermostat/blob/main/documentation/en/self-regulation.md

Another strange thing
If you have the "follow underlying temp change" checked you can try to deactivate it. Else it will reflect your underlying device state which seems strange from what I'm able to see.
