After the upgrade to 4.x my many many Aqara sensors are all marked with a nice looking but not nice-being red exclamation mark.
When looking into the device it’s shown as „device not available“ / timeout.
Funny thing: The devices and their flows seem to work plus in Apples Home App I can even see the correct status (eg door sensor open/close).
Restart App: Done
Any better idea here?
