Upgraded HA Core to 2026.5.0 this morning and it appears to have broken my Zigbee system. I rolled back to 2026.4.3 changing nothing else and it worked again.
Some specific symptoms I saw:
Failed setup, will retry: Invalid socker URI, expected both host and port: socket://192.168.1.51
The native Zigbee settings page appeared to break as well. The Options and Network Information submenus would not display anything. I have attached some screenshots.
My hardware is a SLZB-MR1U running 20250220 coordinator firmware in ethernet connection mode.
Seeing something similar on deconz USB, after restart, websocket is not possible, I need to restart the addon and reload integration, indeed, 2026.4.4 was working...
I had this exact error upgrading from 2026.4.4 -> 2026.5.x (I tried all 2026.5 releases). I fixed this by adding the port to my URI like this: socket://<your_lan_ip>:6638
Then clicked through to apply, everything migrated correctly, and now it's all working again.
