I have migrated my HA from RaspberryPi to Intel-NUC by restoring a backup. HA core works fine.
Only the add-ons behave strange. They all look inactive:
I vaguely recall something similar happening to me a while ago. I don’t know what caused it but I think I shutdown & rebooted my host computer to clear it.
I recently moved my HA install to a new machine and encountered the same issue after restoring the backup to the new machine. As @MaxK has said the solution for me was a full shutdown and restart of the computer. Just restating HA was not enough to get the addons to start and respond normally.
After doing a full reboot of the system all of the addons started as normal and everything was responding as expected.
