Aeotec Multipurpose Sensor vs Ecobee SmartSensor for Doors & Windows

The Aeotec Multipurpose Sensor is better overall. It is the more affordable option, carries a higher owner rating, and integrates with Google Home, Alexa, SmartThings and Home Assistant, while the Ecobee SmartSensor for Doors & Windows only works through an ecobee thermostat and gates most features behind a subscription.

Openness. The Aeotec Multipurpose Sensor is a Zigbee sensor that works across Google Home, Alexa, SmartThings and Home Assistant, while the Ecobee SmartSensor for Doors & Windows is built for the ecobee ecosystem, requires an ecobee thermostat, and reserves motion, arm/disarm and occupancy features for an ecobee Smart Security subscription.

The Ecobee SmartSensor for Doors & Windows does. Its CR2477 cell is rated around 3 years, compared with about 1 year for the Aeotec Multipurpose Sensor's CR2450. The Ecobee also carries a 3-year warranty, so it is the low-maintenance pick on power.

Buy the Ecobee sensor if you already own an ecobee thermostat and mainly want to pause heating or cooling when a door or window is left open, plus simple open/close alerts and long battery life. Just plan for the subscription needed to unlock its security and occupancy features.

Buy the Aeotec Multipurpose Sensor if you want a versatile, better-rated sensor with broad integrations and added temperature and vibration sensing, all without a subscription. It suits SmartThings, Hubitat and Home Assistant users who want flexible automations on a Zigbee hub.
