Control lights using Google Home

We're aware of an issue where after using a voice command to control a connected device (lights, plugs, thermometers), all following voice commands produce the message "Something went wrong...". 
We're actively working on a permanent fix. In the meantime, the following may fix the issue:
  • Mute/unmute Google Home by tapping the microphone mute button on the back of Google Home.

Can't pair Philips Hue bridge with Google Home

  1. Check the following items on your Philips Hue bridge:
    1. Is your Philips Hue bridge powered up?
    2. Have you plugged your bridge into your Wi-Fi router?
    3. Are all the lights on the top of the bridge illuminated?
  2. Make sure your Google Home and Philips Hue bridge are on the same Wi-Fi network and connected to the same router. 
  3. Reboot Google Home and the Philips Hue bridge.
Google Assistant can't control lights
If your Google Assistant is you having trouble controlling your lights, choose the scenario below that matches your current naming scheme and try renaming your device in the Google Home app.  
  1. If you're controlling lights that are connected to plugs or switches, add the word <light> to the name of the device.
  2. If your device name includes a room name (i.e. Kitchen light,) try removing the room name from the device by renaming the device.
  3. If your device name includes numbers or special characters (i.e. The #1 Lights,) try renaming the device and removing numbers and special characters.
  4. If you have two devices with the same name (i.e. Table light up and Table light down,) try renaming one of the devices.
