Philips Hue Secure Contact Sensor Not Working? Here’s How to Fix It

Step-by-step fix guide | Philips Hue Secure

Try this first — Check you have a Philips Hue Bridge set up. Hue says the Secure contact sensor “requires a Hue Bridge-controlled Hue setup, as well as the Hue app.”

This guide is for anyone whose Hue Secure contact sensor isn’t reacting when a door or window opens, or won’t connect. The steps come from Hue’s UK page for the Secure contact sensor and Hue’s setup guide for the sensor.

What This Problem Means

The Secure contact sensor has a magnet, which is the smaller piece, and Hue recommends putting the magnet on the part of the door or window that moves. The sensor needs a Hue Bridge: Hue says “For a Secure contact sensor a Bridge is required”. It runs on a CR2 battery.

Common Symptoms

  • Your lights don’t react when the door or window opens
  • The sensor won’t add to the Philips Hue app
  • The sensor is fitted on a steel or magnetic surface
  • The sensor is fitted outdoors

Safe Checks You Can Try

1. Check you have a Hue Bridge

Hue says “For a Secure contact sensor a Bridge is required”, and that it “requires a Hue Bridge-controlled Hue setup, as well as the Hue app.”

2. Check where the sensor and magnet are fitted

Hue recommends placing the magnet, the smaller piece of the sensor, on the part of the door or window that moves.

Hue doesn’t recommend installing it on steel or magnetic surfaces.

3. Use it indoors only

Hue says: “The Secure contact sensor is designed for indoor use only.”

4. Test it before you fix it in place

Hue recommends testing the sensor before you mount it permanently.

5. Note the battery type and lifetime

The sensor uses a CR2 battery, and Hue gives its battery lifetime as 2 years.

6. Reset the sensor in the app

To reset it, Hue says to “navigate to the edit screen of your device and tap on the Reset button”.

7. Add it to the Philips Hue app again

Hue says to add it by “going to the Hue App > Settings > Devices and tapping on the + button”. If your product doesn’t have a QR code, “tap No QR code to add it by searching or using its serial number.”

Hue’s setup guide also adds it from the Home tab: tap the three dots icon, then tap Add devices, and “Choose a Room to add the Secure contact sensor to.”
