2026 verdict
If a cold bedroom or an unpredictable schedule is the real problem, the Ecobee Smart Thermostat Enhanced is the smart thermostat to choose over the Sensi Smart thermostat.
It supports remote SmartSensors, detects occupancy and proximity, sends temperature alerts and pairs a 4 inch colour touchscreen with 5 GHz Wi-Fi and Bluetooth. The Sensi Smart thermostat is the simpler and cheaper wall unit, with a wide 5 inch monochrome display and physical buttons, and it matches the Ecobee on Google Home, Alexa, SmartThings and Home Assistant, humidity sensing, automatic scheduling and a three year warranty. Only the Ecobee works with Apple HomeKit, and neither supports Matter. Pick the Ecobee Smart Thermostat Enhanced for multi-room comfort and presence-based savings, and the Sensi Smart thermostat for a home that heats evenly and a plain, dependable unit.

What the differences mean
Room sensors and occupancy
The Ecobee Smart Thermostat Enhanced supports remote sensors and detects occupancy, so it can favour the room people are actually in. The Sensi Smart thermostat supports no external sensors and has no presence detection, so it heats to the reading at the wall.
Screen
A 4 inch colour touchscreen that shows the weather on the Ecobee, against a wider 5 inch monochrome display with physical controls on the Sensi Smart thermostat.
Wi-Fi and Bluetooth
The Ecobee joins 2.4 or 5 GHz networks and pairs over Bluetooth. The Sensi Smart thermostat is 2.4 GHz only, which matters on a router that hides the 2.4 GHz band behind one combined name.
Alerts
The Ecobee alerts you to sudden temperature drops and spikes while you are away. The Sensi Smart thermostat lists no temperature alerts.
Trim plate
A trim plate ships with the Ecobee Smart Thermostat Enhanced; the Sensi Smart thermostat does not include one.
Which one to buy if
- one room always runs colder than the rest
The Ecobee Smart Thermostat Enhanced supports remote sensors to heat that room.
- you want a plain thermostat for Google Home, Alexa, SmartThings or Home Assistant
The Sensi Smart thermostat matches the Ecobee on those platforms and on warranty for less.
- your router is 5 GHz only near the thermostat
Only the Ecobee joins 5 GHz Wi-Fi.
- you want an alert when the house gets too cold while you travel
Only the Ecobee sends temperature alerts.
- you would rather press buttons than tap a screen
The Sensi Smart thermostat uses physical controls and a wide monochrome display.

What owners say
Ecobee Smart Thermostat Enhanced owners praise a bright, responsive touchscreen and an app and web portal they call polished, with setup described as very Apple-like. Remote sensors are what they single out most, a must-have when the thermostat hangs in a rarely used hallway, and many report lower bills, sometimes helped by a utility rebate, plus energy reports that separate auxiliary heat on a heat pump. Sensi Smart thermostat owners describe a guided self-install that took minutes, physical buttons they prefer to a touchscreen, easy heat and cool schedules, geofencing and fan circulation settings. Their gripes are the Sensi app accepting US and Canadian addresses only, occasional Wi-Fi drops and the lack of any remote sensor support.
