Overview
The SNZB-04P is a Zigbee door and window sensor that tells you when an entry point opens or closes. Fit it to a door, window or any other opening to build automations, such as switching on a light when a door opens or sending yourself a notification.
It includes a tamper alert, so you know if someone interferes with the sensor, and the CR2477 battery is included in the box, so you can start using it straight away.
