KartoffelToby / better_thermostat

This custom component for Home Assistant will add crucial features to your climate-controlling TRV (Thermostatic Radiator Valves) to save you the work of creating automations to make it smart. It combines a room-temperature sensor, window/door sensors, weather forecasts, or an ambient temperature probe to decide when it should call for heat and automatically calibrate your TRVs to fix the imprecise measurements taken in the radiator's vicinity.

Please add a max temp setting, so that we can control ACs for heating #1129

Currently we can select AC entities as thermostats with no problem, but when activating BT selects high temperatures above 26° which is fine for a radiator but way too much for an AC. Please add this as an additional setting.

In the latest version it seems we could select an AC but only additional to a thermostat which isn't helpful if you only use the AC for heating and cooling.

I really would use BT to control my ACs

To add some more background: ACs get more and more popular as a cheap alternative to normal heatpumps. They have often the problem, that their build in temp sensor works great for cooling but when heating it is not reliable at all. This actually led me to get started with HA at all as I want to connect external temp sensors and control the ACs

i would be too interested in exact the same thing

Me too

Same here - running Daikin air-to-air heat pumps for AC / cooling in summer and also as a hybrid heating system in combination with PV. I think the usage of AC for heating and hybrid systems are becoming much more popular so that would be a great feature to have.

You need to add the climate as an heater too, then it shoud Work

Schm1tz1 commented 9 months ago

I see that it does work in general .The only issue is that it will only allow heat/cool automatic mode and have BT decide. In a split-setup you run into conflicting settings when at the threshold such that the AC unit will lock each other. Also you might want to decide on external parameters or integrate into automations. I think there's already another issue/feature request on that topic.

@escamoteur - just wondering if one could separate AC / heating by using 2 different BT entities. That way you can also handle potential different offsets and offset behaviour. For me I see that AC setpoint is more or less 1-2 degrees higher because of some overshoot in cooling but for heating it's the other way around. Also for AC / air-to-air heatpumps that are mounted on inner walls (which is quire common, e.g. above doors) the offset should be more stable as there is no influence on the measured temperature from the outside walls. I have that case and you only need to estimated the correct offset once for heat/cool and adapt your setpoint accordingly. Nothing needs to be adapted, no matter if it's -10ºC or 10ºC outside.
