I have a Google Home with multiple speakers, one Roborock and a Philips Hue light network set up.
Whenever I ask Google to sync my devices, I always get the answer "...one or more devices are not available". I tried to remove and re-initiate the connections to Roborock and Hue services already. I checked my routines for unknown things. I also plugged off and on all the devices and restarted my router already. Without success so far.
Actually, all other commands work fine and I can start/stop and turn on/off everything without problem. As long as I do not change anything. But when e.g. I rename a lamp in Hue, the trouble starts until I dis- and reconnect the whole Hue service again.
So how can I finally check, which devices Google is missing? In the past I had also connected other things (like Dyson fan, baking oven, etc.) but removed already.
Thanks for reaching out — let's get this sorted.
Please check if you are getting the same response from all your Google Home and Nest devices. If you are, try doing a sequential reboot of your entire network by unplugging and replugging it for five minutes. Try to sync your smart devices again once your network is up and running.
Let me know how it goes.
Tried to ask each one of my 3 speakers and each one responded with the same error.
After that, I unplugged all speakers, the Philips Hue bridge, the Roborock base station and finally the router - waited 5 min - and replugged them again and waited all the devices to finish the reboot.
Again I asked each speaker and got the response with the same error.
What can I do next to catch the problem?
All the devices are turned on by „main switch“. However, in the past I had devices (1 additional Hue light bulb and 1 LifX bulb) which were connected in the past but are removed from the system already. Could they be still a problem?
Connected phones/tablets: No tablet, but phones yes. Old and new iPhones had/have Google Home app.
Thanks for the information. It is possible that your speaker is still detecting those old devices. Let's check if you can still find them from the Assistant Settings. Are you using the public preview version of the Google Home app? If so, follow these steps below:
Also, check your linked devices on your account and see if you can remove it from there. Click here to see all your devices.

I don’t use the public beta. Just the regular Google Home app from the iOS App Store. But anyway, I found the devices under the assistance setting. It shows my 3 speakers only. But no other device: no Philips Hue nor the Roborock. And also no unknown device.
From the linked devices in my account, I now have removed any link to all computers/tablets/phones (indeed there was my tablet, whose link I did not know), except the iPhone that I’m using right now and my speakers.
I still have the same error as before.
That's weird! Please create a new home structure on the Google Home app. Once done, move all your devices from the old one to the new one then immediately remove the old home structure. Check if you still get the same response when syncing your devices.
