Nest vs Hive

Hi Guys

What’s peoples opinions on nest vs hive in regards to hassio. Can you use hassio to set the thermostat temperature?

My intention is to upgrade my TRV’s to eurotronic-spirit-smart-radiator-thermostats and *install either a nest or hive thermostat to control the boiler.

My understanding is that the eurotronic-spirit TRV will post the room temperature to hassio.

Therefore as an example if my kids room got too cold in the night I should in theory be able to detect it and send an instruction to override the thermostat (nest/hive) temperature to turn on the boiler which will then heat up that individual room or any room’s TRV that hasn’t reach it set temperature?
