Nest Learning Thermostat vs Honeywell Home T5 Smart Thermostat

Nest Learning Thermostat, thanks to its self-learning schedule, occupancy and humidity sensing, remote sensor support, dual-band Wi-Fi and Matter compatibility. Honeywell Home T5 Smart Thermostat wins on price, on-device voice control and its system health monitor with filter reminders.

Nest Learning Thermostat watches how you adjust the temperature and builds its own schedule around your routine, then uses occupancy and geofencing to drop it when the house empties. Honeywell Home T5 Smart Thermostat holds a 7-day schedule you define, with geofenced Auto Home and Away, but it never learns.

Honeywell Home T5 Smart Thermostat does, alongside Alexa and Google Assistant. Nest Learning Thermostat has no Apple HomeKit support at all, covering Google Home, Alexa, SmartThings, IFTTT and Matter, with only partial Home Assistant integration.

Nest Learning Thermostat supports remote temperature sensors, selected by time of day, so it can favour a bedroom at night. Honeywell Home T5 Smart Thermostat supports no external sensors, so it measures only where it is mounted.

Nest Learning Thermostat uses a 2 inch high-resolution colour LCD at 480 x 480 controlled by a dial, showing temperature, time and weather. Honeywell Home T5 Smart Thermostat has a much larger 4.95 inch monochrome touchscreen showing temperature and time, without weather.

Buyers who want Apple HomeKit support, a big readable touchscreen and HVAC maintenance reminders at a lower price, and who are happy setting their own schedule. If you would rather the thermostat learn your habits and use room sensors, Nest Learning Thermostat is the better fit.
