How to choose
Heat pump compatibility first
Heat pump use differs by model, so check it before anything else. The Nest, Honeywell, ecobee, Sensi and meross all work with heat pumps, but the Honeywell is for heat pumps with electric backup. The Honeywell and meross require a C wire, and the ecobee includes a Power Extender Kit for homes without one.
Schedules and sensors
A schedule sets heating and cooling by time of day. The Nest, Honeywell, ecobee, Sensi and meross all offer scheduling, with the meross using a 24/7 flexible schedule and the Honeywell using 7-day programming. Sensors add room-level comfort: the ecobee supports SmartSensors that detect occupied rooms, and its occupancy sensing preheats or precools before you arrive. Pick scheduling first, then add sensors if rooms differ in use.
Voice, apps and alerts
Voice and app control decide how you adjust temperature day to day. Alerts differ: the Nest sends HVAC monitoring alerts, and the meross sends filter life and system malfunction alerts. The ecobee app also shows system activity and energy use.
