Philips Hue Secure Contact Door & Window Sensor - White

The contact sensor uses a CR2 battery.

No, the Philips Hue Bridge is required for the contact sensor to function fully.

Carefully open the sensor housing and replace the old battery with a new CR2 battery, ensuring proper polarity.

While the sensor is designed to withstand a range of temperatures (-20 - 45 °C), it is not waterproof, and therefore, not recommended for outdoor use.

The Philips Hue Bridge supports multiple sensors, allowing you to secure various entry points in your home.

Remove the battery for a few seconds and then reinsert it. This should reset the sensor.

Ensure the sensor is within range of the Hue Bridge, check the battery, and try resetting the sensor by removing and reinserting the battery.

Verify that notifications are enabled in the Hue app settings, and that your smartphone has an active internet connection.

Double-check that the automation is correctly configured in the Hue app, and that the lights are linked to the sensor trigger.

Check the battery level and ensure the sensor is within range of the Hue Bridge and that the bridge is online.
