One of these little sensors in the hallway (got more dotted around the house), and an OpenTherm shield hooked up to Home Assistant (via an ESP32) - It does much more than just acting like a thermostat. Times and temperature are all controlled by HA, and I get to log all the data in great detail. Unless you are technically minded, probably not for you.

A Hive or Nest thermostat would probably be cheaper, and much easier to set up.

We have a Hive but it isn't open therm. If I went combi and Veissmann I was wondering if it's worth swapping to one that supports it such as Nest.

I suspect you would be better off in the long term going for a Tado or Wiser - Hive (owned by British Gas) have history for discontinuing support for certain Hive products. Mind you, Nest (owned by Google) isn't much better... Personally. I prefer an open source solution so that I can have access to the code and make changes long after the original developers have given up on it.
