2026.4 update just broke all of my Inovelli White Series (Matter/Thread) Fans. Can’t turn them on/off anymore within HA getting error “Failed to perform the action fan/turn_on. No metabase for model unknown_65530”. Deleting and re-creating Matter pairing does not solve the problem.
Update: NOTHING works to repair the damage 2026.4 did to my Inovelli White Fan Switches (all 9 of them I had working). I did full restore back to 2026.3.4 including Matter & Thread restore. I factory reset and re-paired fan switches and now getting different error "Failed to perform the action fan/turn_on. Endpoint 1 on node 159 not found" even though all the endpoints show up under the node information in Matter server. Nothing working to repair the damage.
