Ecobee - Free SmartSensors for doors and windows 2-pack YMMV
Meet the contact and motion sensor that works with your ecobee Thermostat and the new ecobee Haven home monitoring service to notify you about entries, exits, and when motion is detected inside in your home while you are away.
Haven uses Wi-Fi and geofencing technology to automatically arm and disarm your home based on your presence, no keypads and codes required.
With Haven, SmartSensor adapts to your presence, so when you’re home it continues to monitor what is open and closed, but the motion detection turns off. You can also customize alerts for monitoring where and when you want them, like your front entryway after school.
For a limited time, get a 2-pack of sensors when you try ecobee Haven free for 1 month, no credit card required.*
