Working with classic AAA batteries, the sensor has low energy consumption and a battery life of up to 6 months.

After connecting to the Tellur Smart app, you will receive notifications directly on your smartphone when a door / window is opened / closed, the batteries are running low, and most importantly, when someone tries to destroy or disconnect the sensor.

The history record helps you track the days and hours when the door/window was opened/closed.

The WiFi Smart Door and Window Sensor is only compatible with 2.4GHz WiFi frequencies and can be activated by voice via Google Home and Amazon Alexa.
