Desperately seeking help. Since mid December our google chromecasts, hub, speakers, tapo smart plugs and smart bulbs, which had been previously working very well, suddenly went 'offline' in the Google home app and although the will work individually (e.g. we can cast to chromecast from a smartphone). There is no control in the google home app and no interconnectivity between devices (e.g. we can no longer command a bulb to turn off, broadcast a message from one device to another). To try to rectify the problem we have tried hard resetting, deleting the app. We exhausted google's help with no resolution. To make matters worse, we rest the google wifi mesh network to try to resolve the problem, it hasn't and now we can't get it back online again, so we have very patchy Internet in some rooms of the house. The only device we have been able to get online is our nest doorbell. Our Internet into the house service seems fine. Any ideas welcome!
This sounds like a wifi issue, but I'm sorry I don't have any help to offer since I'm in essentially the same condition. Google Home appears to be far from ready for prime time since it has no way to check or modify wifi connectivity and/or parameters and no way (despite what online help articles say) to delete or check connectivity on individual devices in the app.
Thanks for posting and for being a step ahead of us.
I know how it feels when something isn’t working as it should. A few things: what is the exact message that you are getting from your Google Home app during setup? Is the distance during the setup at least within 15 feet? You can try using another phone to further isolate the issue.
Looking forward to your response.
For the speakers, hubs and chromecast - we can install them to google home the installation process goes through and they show up but then immediately state 'offline' in the google home app. We can use them as standalone units though, e.g. we can cast to the hub from a mobile, it will tell us the latest news when asked, it will search the internet, it will play netflix. Similarly, the chromcast can be cast to from our mobile devices from Netflix, Disney+ iplayer etc. The problem comes when a command involves more than 2 units e.g. asking it to broadcast to another room - the devices says okay broadcasting to 'The Room' but nothing happens at the other end (e.g. in the Room).
Our nest doorbell shows as online in google home - however it doesn't ring on any of the speakers/hubs and doesn't send push notifications to our mobiles - therefore we have no clue when the doorbell is rung.
For the google/Nest Wifi -The Google home app goes through the whole installation process looks like it is going to connect it... says gathering more information/data (or something like that), then says 'Something went wrong.'
All the problems are exactly the same using a different device and the distance during set up is less than 15 feet.
Chiming in — apologies for the late response. Thanks for the additional info. How many Google Wifi points you have at home?
Let's start from moving your points closer to the router to get a better signal. From your router, make sure to watch the signal of your connection keeping the Wi-Fi signal to 3 bars. Once you notice that the signal bars are decreasing, go back to the point where you get 3 signal bars as an indication that it gets a stable Wi-Fi connection from your router. Do the same on all Wi-Fi points and let's see if it improves your network connectivity.
Keep us posted.
