Hi David, Thanks for getting back to me and sorry for keeping you waiting! I have now sent my logs through the app like in the article you described. I also entered the message "replyId=1655944 from the EN forum" in the email body so maybe you can search for that in your CRM-system. :)

Restarting the whole mesh network has done absolutely nothing. I've read other topics where people have gotten their offline clients showing again by just rebooting the whole network, but it does absolutely nothing for me. Resetting the network would be A LOT of work as I use quite a lot of different wifi-plugs offline (through home assistant OS) that have reserved adresses because otherwise the connection to HAOS breaks. And I guess resetting the network actually removes all settings and goes back to factory defaults?

Edit: Do you want to know something funny??! Nothing I've tried doing since the beginning of december has helped... But somehow sending the logs to you made the network refresh and got all my clients back! This HAS to be some kind of bug somewhere. But at least now I know how to get them back. Let me know if you need something more from me and I'll gladly try helping you pinpoint the problem in the application. At least now we've got a clue as to what is happenin.
