Bought Google Wifi a few months ago and has been working fine until other day. Internet and power went out due to storms but since then our internet service is back but there has been no Wifi signal. Tried factory reset on all devices and now Google Home App can’t find Google Wifi device to set it back up.
Sorry about the issues you're having with the Home app seeing your WiFi network. I imagine that's quite frustrating not to be able to access your data and settings. I'll be happy to work with you to get things back to normal. Have you tried clearing the cache from the Home app? If you haven't, I would give that a try first and see if it clears up the issue. If that doesn't work, try uninstalling the app and reinstalling it. Once you log in, your settings will still be intact, so you won't have to set your devices up again.
Once you have tried those two steps, if you're having issues still, please let me know and we can look at additional steps. I look forward to your response.
