What the differences mean

How it connects

The Ecobee SmartSensor for Doors & Windows joins an ecobee thermostat over 2.4 GHz Wi-Fi and does nothing without one. The Eve Door & Window uses Thread and Matter, so it needs a Thread border router such as an Apple TV, a HomePod or another Matter hub, but no Eve hub.

Platforms

The Eve Door & Window works natively with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. The Ecobee SmartSensor for Doors & Windows reaches Google Home, Alexa and Apple Home only through the ecobee thermostat, and not Home Assistant or SmartThings.

Battery

The ecobee sensor is rated for 3 years on a CR2477 coin cell. The Eve Door & Window is rated for 11 months on a half-AA ER14250 cell, so expect roughly a yearly battery change against one every few years.

Occupancy

The Ecobee SmartSensor for Doors & Windows adds occupancy detection with a 120 degree view and a 16 ft range, which ecobee uses for its heating and security modes. The Eve Door & Window only reports open and closed.

Warranty

Ecobee covers its sensor for 3 years and Eve for 1 year.

What owners say

Ecobee SmartSensor for Doors & Windows owners single out the thermostat pausing heating or cooling when a door is open, and many feel caught out by the ecobee Smart Security subscription that motion, arming and occupancy alerts need, and by Alexa and Google support that stops at arming. Eve Door & Window owners talk about reliability, calling it rock solid on Thread where cheaper sensors dropped off, and about pairing it to Apple Home and Home Assistant at the same time; their warnings are the Thread border router it needs, a QR code that changes after the Matter upgrade, and a body a little chunky for inset sliding doors.
