Philips Hue Bridge Lights Explained: What Each Light Means

Step-by-step fix guide | Philips Hue

Try this first — Read the Philips Hue Bridge’s three lights from left to right: power, network, then Hue internet services. If only the third light is off, update the Bridge software in the Philips Hue app.

This guide is for anyone who wants to know what the lights on a Hue Bridge mean, and what to do when one stays off. The meanings and steps come from Hue’s guide to the Bridge lights and Hue’s other support pages.

What This Problem Means

The Hue Bridge has three lights and a round light around the button. Hue says the left light shows the Bridge is connected to power, the middle light shows it is connected to the network through a router or modem, and the right light shows it is connected to the Hue internet services. The round light around the button shows the Bridge is producing a Zigbee signal.

Common Symptoms

  • The left light on the Bridge is off
  • The middle light is off
  • The third (right) light won’t come on
  • The lights started blinking after you pressed the reset button
  • You’re not sure whether a reset has finished

Safe Checks You Can Try

1. Left light off: check the power

The left light shows the Bridge is connected to power. Hue says: “Make sure the Bridge is connected to both power and to your router.”

2. Middle light off: check the router connection

The middle light shows the Bridge is connected to the network, through a router or modem. Check the Bridge is connected to your router, then wait until the first and second lights come on.

3. Right light off: update the Bridge software

Hue says the third light “will not turn on if the Bridge is not running the latest software version.”

In the Philips Hue app, go to Settings > Software update and follow the app’s instructions to update the Bridge’s software. Hue says you may have to repeat this step. Once the Bridge has been updated, the third light should turn on.

4. Still off? Check Hue’s service status

If the third light is still off after updating, check Hue’s service status page, which shows the status of Hue services, including the Hue cloud. When everything is working, it says “All Philips Hue services are up and running”.

5. Reading the lights during a reset

If you reset the Bridge, Hue’s US Bridge reset guide says the lights on the front “will start blinking, confirming the reset process has begun.” The reset is complete, and the Bridge is ready for setup, once the first three lights are “solid blue”.
