Currently I am only observing the beta stream. Unfortunately I have too less time to actively test new features. Therefore my proposal bases on assumptions.
It sounds that the new feature only supports rules that support heating in case of low temperatures. However, in all of my applictions I suffer more by too high temperatures than by too low ones.
Therefore I would see also a benefit, if once the feature would support a cooling case for the scenario of high temperatures.
This mod uses the existing relay temperature rules where you can set the activation temperature higher than the deactivation temperature so the relay controls a cooling fan. The mod is bringing the battery temperature into those available for temperature control.
