2026 verdict
French doors that should pause the heat are the job for the Ecobee SmartSensor for Doors & Windows, not the Centralite Micro Door Sensor.
It pairs with an ecobee thermostat over 2.4 GHz Wi-Fi, can hold HVAC when the door stays open, lists occupancy as well as contact, keeps a history, and is rated for 3 years on a CR2477 with a 3 year warranty. Motion alerts need an ecobee subscription. Home Assistant, SmartThings and Matter are not supported. Google Home, Alexa and Apple Home need the thermostat. The Centralite Micro Door Sensor is the small Zigbee body, 33 x 15 x 44 mm, for SmartThings or Home Assistant, and it is the more affordable. Its battery life is not published. Choose the Ecobee sensor when the French door should talk to the thermostat. Choose the Centralite sensor when the door only needs Zigbee open and close.

What the differences mean
Thermostat or Zigbee hub
The Ecobee SmartSensor for Doors & Windows is built to pair with an ecobee thermostat over 2.4 GHz Wi-Fi, with no separate hub, and it can pause HVAC. The Centralite Micro Door Sensor needs a Zigbee hub and does not speak Wi-Fi. It will not pause an ecobee system by itself.
Occupancy
The Ecobee SmartSensor for Doors & Windows lists occupancy as well as door and window contact. Motion alerts need a subscription. It does not list a separate motion sensor, and it does not measure temperature. The Centralite Micro Door Sensor lists contact only. Its temperature sensing is not published.
Platforms

The Ecobee SmartSensor for Doors & Windows reaches Google Home, Alexa and Apple Home only through the thermostat, and it does not support SmartThings, Home Assistant or Matter.
Size and warranty
The Centralite Micro Door Sensor measures 33 x 15 x 44 mm and weighs 1.28 oz, on a CR2450 with no published life and no published warranty. The Ecobee SmartSensor for Doors & Windows measures 60 x 29 x 21 mm, weighs 38 g, uses a CR2477 rated for 3 years, and carries a 3 year warranty. It is the larger body and the longer documented warranty.

What owners say
Owners of the Ecobee SmartSensor for Doors & Windows keep coming back to one automation: the ecobee thermostat pauses heating or cooling when the door or window stays open. They also like a small body, fast open and close notices on a garage or entry, and a battery status that is easy to see. The complaint that dominates is the subscription. Without ecobee Smart Security they feel stuck with basic notices, and they mention a high price per sensor, thin Alexa and Google routine control, and no temperature reading, which surprises people who know the brand's room sensors.
