Nest Learning Thermostat (4th gen) vs Sensi Touch smart thermostat

The Nest Learning Thermostat (4th gen) is the stronger thermostat overall, with occupancy and ambient-light sensing, temperature alerts, a System Health Monitor, dual-band Wi-Fi, Matter and a bundled remote sensor. The Sensi Touch smart thermostat wins on price, owner rating, a 3-year warranty and Apple HomeKit support.

It comes down to intelligence and hardware. The Nest 4th gen learns your routine, senses occupancy and ships with a remote temperature sensor and trim plate, while the Sensi Touch smart thermostat is a simpler scheduled thermostat with a color touchscreen but no occupancy sensor, no included sensor, and 2.4GHz Wi-Fi only.

No. Only the Sensi Touch smart thermostat supports Apple HomeKit, along with Alexa, Google Home, SmartThings and Home Assistant. The Nest Learning Thermostat (4th gen) skips HomeKit but adds Matter and works with Google Home, Alexa and SmartThings.

The Nest Learning Thermostat (4th gen) includes a Nest temperature sensor and a trim plate in the box, so you can balance rooms out of the gate. The Sensi Touch smart thermostat ships with neither, and its trim plate is an extra-cost add-on.

Buyers who want an affordable, highly rated touchscreen thermostat with Apple HomeKit, on-device voice control and a long 3-year warranty, and who do not need occupancy sensing, learning or a bundled remote sensor.

Google-ecosystem households that want a self-learning schedule, occupancy and ambient-light sensing, HVAC health monitoring, Matter and an included remote sensor, and are willing to pay a premium for it.
