@lars I am new to the forums as many are on this thread and are experiencing the same issues. I am unable to fully unlink my account from google home control devices. It shows i have 19 after unlinking previously and have lost complete control from google home. Can you assist with unlinking my accounts?
It was not GH firmware. I received an email from both Google and SmartThings about an update that would require relinking devices. When I opened my Google Home app, it had āSmartThings (upgrade!)ā at the top. I went back to the ST email and it instructed me to unlink my ST and relink it. I did that and now I, like many others, are in this mess.
I guess it could have been GH firmware that triggered the ST upgrade request but since Iām already past that point, I donāt know if my firmware is new or not.
My firmware on one my GHs is:
1.27.97091
I havenāt heard from @Lars yet but itās the weekend.
I just tried unlinking again this morning and it worked. No idea why. Maybe they did some backend fixes. I added it back and it looks like itās only got one copy of each actual device. So, I guess itās fixed.
I have manged to unlink and link today too
My account as well please
I managed to unlink and relink, but I still have one light that will not respond. Itās my most used device and I keep being told it cannot find a device with that name when I can see it in the Google home control app.
Hi @Lars,
I am trying to link SmartThings and google home but after adding the device, It goes to the Authorize page where-in after authorizing I am getting following error "Something went wrong, please try again"
I tried all steps mentioned in this forum. Re-linking the account. Re-installing the app. Nothing seems to be working for me
Can you please assist?
Lars - thanks so much for all of your work on this. It appears they have corrected the unlinking issue and I also am good to go now. Have a great day!
Can you look at my Samsung smart things account with my issues with the connectivity issues with Google home?
How do I PM you?
@Lars Is there any other way to get you account info outside PMās? my account here is brand new and doesnāt allow PMāing yet 
Iām having the issue again after trying to fix some lights being in the wrong room
@Lars I just bought a second Google Home today and everything got all messed up. I now too am having the issue where I canāt unlink my ST account and nothing is working right.
Hey @Lars,
I too am experiencing this issue where I cannot unlink. Opened a ticket with Google Home support and posted a thread in their support forums. https://productforums.google.com/forum/#!topic/googlehome/F-l6Am2U5Ic;context-place=forum/googlehome
Iāve tried the usual of factory resetting the Google Homes, clearing cache/data of both apps, rebooting phone, and still not able to unlink. Any help or visibility on this matter would be most appreciated. Thanks in advance.
I also canāt unlink my ST account from Google Home. I keep getting a āsomething went wrongā error. I tried to limit the devices GH can access through the āGoogleā smart app in ST but GH continues to list all 34 of my devices as connected.
@Lars , I appreciate all you have done and are doing and would really appreciate it if you could take a look into my account as well. I donāt have any thermostats but I do have some custom device handlers. I would send you a PM but am unable to do so since I am a new member.
I have the issue where I cannot unlink smartthings in google home. Please fix this for my google account.
@Lars can you get my home control reset unlink smartthings in my GH?
Hi @Lars
Could you please help me? Iām not able to link Google Assistant and Smartthings (and not able to PM you). Could there be a problem with that Iām not in US? I am always sendt to: āhttps://graph.api.smartthings.com/ā instead of āhttps://graph-eu01-euwest1.api.smartthings.comā. Another SmartApp I had same trouble with was fixed by changing from US -> UK adress.
My wife is unable to unlink her SmartThings account, but mine is fine. This is tied to her Assistant account, not the Google Home hardware.
Lars I am having the same issue with not being able to unlink. How do I PM you?
