Multiple, configurable pre-sets would be a huge improvement for my use case. I need different settings for different parts of the day. Pre-sets could include Boost, Night, Morning, Afternoon, Evening etc.
@irxy, closely related to underfloor heating with high thermal inertia are storage heaters. We have them, they are a nightmare to control because they only charge up over night irrespective of what the weather will be like the next day (so some days we roast, some days we shiver). If I could take inputs from weather forecasts as well as temperature ramps due to thermal inertia I could probably create a more optimised charging profile for the heaters.
I recommend you look at advanced control strategies such as PID - Proportional Integral Derivative. Very common closed loop feedback strategies. I have no idea how HA would implement such approaches though. There is a community discussion here.
