I have not had any issue with Smartthings, Google home, and everything I have linked up to it. From day 1 I have had my Schlage Camelot Zwave door lock, 4 lutron zwave light switches, my Rachio Sprinkler, etc all linked up. I recently upgraded my router to a mesh network and has some issues probably unrelated but basically factory reset my hub, then had to relink all my devices. I got that done with little issue.
All 11 devices I have show up and work just fine from the Smartthings app, and all 11 devices show up on the smartthings online hub menu. When I link my devices to google home first off it says 14 which is odd since there are only 11 but then when I go to add them to different rooms which is the next step in the process it only shows 10. The door lock is not one of them. I know for a fact this door lock works as I have been using this for at least 3 years with smartthings and ever since I got google home I have been able to voice unlock. So it won’t even show up now. I have told google home to Update Device and it claims it is resyncing with Smartthings. I have gone into the smartthings app > automation > Smart Apps > Google > unchecked allow google assistant to access all device and routines. Checked everything on the list for switches, and made sure under lock my door lock was checked. I then hit save
Go back to google home, tell it to up date, nothing. I remove and read smartthings, still nothing. WTH how do I get my lock back on to Google Assistant?
