Ecobee Smart Thermostat Enhanced vs Honeywell Home T9 Smart Thermostat

Ecobee Smart Thermostat Enhanced, on price, integrations (HomeKit, Google, Alexa, SmartThings, Home Assistant and IFTTT), dual-band Wi-Fi with Bluetooth and a 3 year warranty. Honeywell Home T9 Smart Thermostat wins on its included room sensor, built-in speaker with voice control and system health monitoring.

Yes. Honeywell Home T9 Smart Thermostat includes one Smart Room Sensor with up to 200 ft range and occupancy detection. Ecobee Smart Thermostat Enhanced supports remote sensors and selects them by presence, though the sensor itself is a separate purchase on this model.

Ecobee Smart Thermostat Enhanced, with a 4 inch colour touchscreen at 540 x 540 showing temperature, time and weather. Honeywell Home T9 Smart Thermostat also has a touchscreen showing time and weather, but it is monochrome rather than colour.

Honeywell Home T9 Smart Thermostat includes a C wire power adapter and often fits the existing wall plate when replacing an older Honeywell. Ecobee Smart Thermostat Enhanced includes a trim plate and a power adapter, but installation without a C wire can still be fiddly.

No. Neither Ecobee Smart Thermostat Enhanced nor Honeywell Home T9 Smart Thermostat supports Matter. Both do cover Apple HomeKit, Google and Alexa natively, so most households will not notice the gap in daily use.

Anyone who wants a room sensor included from day one, occupancy-following heating, filter and maintenance reminders and on-device voice control through a built-in speaker. For a colour screen, dual-band Wi-Fi, more integrations and a longer warranty, Ecobee Smart Thermostat Enhanced is the better buy.
