Product description

Key Features

Sends an instant alert to your phone the moment a door or window opens or closes, with both states synced so you can check remotely without walking over to look.

A 3 month history log lets you check back on activity rather than relying on catching every real-time notification. Works with Alexa and Google Home for voice control and smart routines, for example lighting a hallway automatically when the door opens.

  • Instant open/close alerts, 3 month history
  • CR2032 battery, ~24 months
  • Works with Alexa, Google Home
