Lights stopped working yesterday and all show up as offline. Everything else work including automations. Have rebooted router and hub. But google does not recognize them.

Try Reconnecting manufacturer's app to Google Home app in Settings. >. Works with Google.

Hi @Bobh2,

Thank you for posting in the community. I understand you're having issues because your smart lights are showing as offline and Google does not recognize them, even after you've rebooted your router and hub. I'm happy to assist you.

To better understand the cause of the issue, please provide the information requested below:

Have you contacted the manufacturer of the lights?
Is the Google Home app the only app you used to set up the lights, or do they have their own dedicated app?
- If they have their own app, are you able to set the lights up there successfully?
Do you have the latest version of the Google Home app installed?
Did you remove the lights from the Google Home app after they went offline?

@SmartHomeH-TAGS, thank you for your help on this thread.

Keep me posted.

Regards,

Anders

My light is offline as well - same problem. I have removed and reconnected the light and rebooted router but still shows light as offline in app and via voice commands.

Did you ever resolve this issue?
