Smart Thermostats
Smart thermostats compared on the specs that actually decide it — C-wire requirement, heating and cooling stages, heat-pump and accessory terminals, remote sensors, and Matter support.
We compare 12 smart Thermostats from 6 brands — Google, ecobee, Amazon, Honeywell Home, Copeland, Mysa — priced from $79 to $259.99. Each one is scored across 8 categories (C-Wire Freedom, HVAC Coverage, Multi-Room Sensing and others), calculated from published specifications rather than opinion, which is what makes the 26 head-to-head comparisons below directly comparable.
