Hi all, this is a repost from "configuration" group.
Everything has gone to sh*t and I REALLY need help.

Couple of days ago I migrated my ZHA network to newly bought ZBT-2 stick. Went extremaly well, with just minor hickups. Eventually all devices stabilized to new Zigbee controller.

2hours ago I wanted to add Zigbee2MQTT (additional to existing ZHA) to test and see how it works. I installed the addon, connected my old Phoscon Conbee 2 stick and Z2M started without issues.
HOWEVER almost all my Zigbee devices connected to ZHA/ZBT-2 went offline and now I can't control anything! I've tried restarting HA, rebooting my Pi4, then I stopped and uninstalled Z2M, unplugged Conbee2, now I've even restored from the backup... NOTHING WORKED! All devices are still offline and I've GOT ABSOLUTELY NO CLUE how to restore them.

PLEASE HELP!
Thanks

Apparently all of my devices have disappeared from ZHA and now I need to reconnect them one by one. Anybody has any idea on why that might've happened, and how can I make sure that next time I add Z2M I won't have the same problem all over?

I'd stick to z2m instead of zha but yeah I got nothing, sorry.

Good luck
