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.

What is the feature?

When a room is not used for some time, I would would like to regulate at the lowest possible temperature to save energy. But I do not want to risk to get mold. It would be grate if I could regulate my room at the lowest "mold safe" temperature.

Description

The lowest you risk getting mold when the coldest point in the room gets colder than the dew point. The Dew point can be calculated with the relative humidity and temperature. The temperature of the coldest spot in a room, can be estimates as: T_room - p * (T_room - T_outside) p is a parameter that has to be determined for each room by measuring the cold spot at a cold day.

An upper and lower limit for the temperature would be usefull.

Just use the mold indicator integration and build an automation with it?
