Thanks for reaching out — let me help you out with this.
Was it working before? Make sure your devices are connected to the same network and within the same home structure.
Give these steps a try:
Step 1: Ensure the bulb is working on its own
Step 2: Power cycle the bulb. Turn the switch or plug off for 10 seconds, then turn it back on.
Step 3: Ensure the Google Home app is up-to-date. Reinstalling it might help.
Step 5: Reboot router. To reboot, unplug the Wi-Fi router and leave it unplugged for two minutes before plugging it back in.
Step 6: Reboot the Google Home device.
Step 7: Factory reset the bulb.
Step 8: Use the Cync app to see if the bulb can be found. Using the Cync app to see if the bulbs are visible will help determine whether the bulb is able to communicate via BLE or if there is a potential hardware issue with the bulb.
Note: Do not complete setup with the Cync app, seeing whether the bulb appears for setup is sufficient for this step.
Hope this helps.
Yes, I have tried the above and now the Nest Max at my girlfriend's house controls the lights at my house
My House: Multiple Google and Nest products (Mini, Max, Cameras), with light bulbs from Cync by GE all working correctly. Girlfriend is a family member and user on Nest Cameras in the application.
Girlfriend’s house: Nest Hub Max (serial number: 23021F4AB0WO53) and light bulbs from Cync by GE just setup after the holidays.
My phone: Android Pixel 5 all updates and Cync by GE and everything works fine
Girlfriend’s phone: iPhone 12 with all updates and Google Home that see’s the Nest Max at her house correctly. The Cync by GE was able to set up all of the light bulbs and that application works fine to control the lights. Nest application that sees her house and then the cameras that are located at my house.
I have 16 bulbs in my house that have been setup and working for over a year. This only started last week when I installed the new Nest HUB and four lights at her house. I don't think resetting my 16 bulbs is an ideal solution since they have all been working fine at my house for almost a year. What's the thought process behind resetting all of the bulbs at my house?
Apologies for the delayed response. May we know how your smart lights are going? Is the behavior still the same? We can try to reset just one of your lights and test it out to isolate your concern. Follow the steps above on how to reset your light bulb.
Looking forward to your responses.
