Smart TRV's with boiler unit

Hi,

I currently have a home with 9 (dumb) TRV's combined with a Nest Thermostat and a Nest boiler unit. Since we have a baby now combined with a lot of working from home, I want to be able to control the temperature in each ream individually using Smart TRV's so I don't have to run around the house opening and closing volves wondering if a room will be hot/cold enough.

From what I have read online, this is only really worth it when combining this with a boiler unit (similar to what Nest has now). Reason being that I may want one room to be warmer than the rest of the house at times.

The question I have now is what option will be best for my use case. Some brands that seems interesting to me:

  1. Drayton Wiser, affordable, but UK only?
  2. Tado, expensive, but overall good reviews
  3. Honeywell EvoHome, reliable but expensive

Any other options I am missing? Any pitfalls to be weary of?

Integration with home assistant is a plus.

Thanks in advance for your help!
