I have done this Manual setup Google Assistant - Home Assistant all the way until Enable local fulfillment
it was first done about 3 years ago. I have tested the local access and when the Internet was down it was still able to control my lights.
But really lately it’s become quite fragile , generally when I ask Google to do something it will say home assistant is not available the first one or two times.
And then I had a power outage for an hour and after getting everything back up and running via backups which took until the next afternoon, then the Google connection wasn’t working anymore
you could see in the Google Home app the devices were flashing between available and offline
I tried re linking the connection and it went to the home assistant login page and after that it said failed to connect. Coincidentally home system stopped working and then when I went into my synology virtual machine and pressed connect I saw that there was some code dump
it had been working until that time so I cannot say for sure but it seems like that connection killed
and then I slept on it and then in the morning the connection seems to be working again
machines are set up so that I have synology on 192.168.1.20 and HA VM on 192.168.1.21 and reverse proxy and pihole with cnames.
The Google homes are on the main wifi network with full access to these. What can I do to check if there are any connectivity issues?
