Almost a year later and I'm still plagued with this every time I do an update with Hubitat. We basically can't use any of the google minis (voice commands) to control Hubitat devices for 1-2 days after the updates. It's so frustrating, and I would really like a solution. Same errors I've reported previously. It's like the link between google and Hubitat will temporarily break after the Hubitat updates. If there is even a way for me to manually fix this link after every Hubitat update, I'm fine with that. Else I'm going to have to put my energy into a different smart home solution other than Hubitat.
Some of this seems to be what I'm experiencing. Hubitat updates are a nightmare for Linked w/Google Home
All my google mini's and my Hubitat has a dhcp reservation on my home network and Hubitat is set to dhcp.
