I have just been trying to get as much as I can back up and running then reintroduce each bit by bit.
The Modbus going down is typical, I have only just added that a few weeks ago to monitor my solar system as I am having issues with grid line voltages…
For future reference, before upgrading Home Assistant, check the Breaking Changes section of the release notes for anything related to your configuration. It can help to avoid unexpected failures.
For example, the change to Modbus was listed in 2021.7’s Breaking Changes.
Yeah, I usually do check that quite well (I got burnt before) and knew that the Modbus would need changing, it was the other errors that threw me off track. I did have the changes to the Modbus part just sitting there in Visual Code, thats how I fixed it so fast once we mentioned that the Modbus was the start f the issues.
Now just need to figure out what has changed in MQTT covers that broke my garage door opener…
