I have a Toshiba heat pump and got the extension working great in HA. However the temperature sensor on the heat pump is awful and there is no calibration setting. Usually it maintaints roughly the same temperature in the room, but it can vary by as much as 4c.
I have an external temperature sensor in the room also connected to HA and it is very reliable. How do I best write an automation that keeps the room at the same temp?
I tried to make one from scratch where I raised and lowered the set temperature based on number of seconds it had been outside the desired range, but I failed and it never worked. Anyone got this to work?
