I am using that already, I may have missed some features but it didn't seem to support the more complex requirements I had for my heating. I use the helper to manage the overall heating, by giving it my calculated "average" as the target sensor, and I use the home/away/sleep values. The complexity in my setup is managing individual rooms which I control independently of the overall heating state; it's a fairly large home for the UK and an old one, some rooms come up to temperature much quicker than others and I want them at different temperatures too, so each room is switched as a separate zone using its TRV and sensor.
