Best Smart Thermostats for heat pump compatibility

#1 ecobee Smart Thermostat Enhanced
4.2

Heat pump support was described positively for standard heat pump systems, with the reviewer saying it should work fine for that use.

Pros: display readability, value for money

Pros: app usability, DIY installation ease

Cons: C-wire requirement flexibility, smart-home ecosystem compatibility

#3 Aqara Hub W200
2.0

Heat pump support drew the strongest compatibility criticism because compressor and auxiliary heat controls felt unclear or inadequate.

Pros: smart-home ecosystem compatibility, occupancy detection accuracy
