have been using HA for a few month with some good success this year but started playing up recenty again.
Zigbee devices become unavailable over time or don’t become available when HA rebooted. I have a few WARNING (MainThread) [zigpy.zcl] [0xb432:1:0xef00] Unknown cluster-specific command 36 in my logs
Sometimes HA reports devices as seen very recently in the settings but they don’t respond or show wrong status.
It’s in a different room to Wifi NW and hard wired. System is Pi4 with Samsung Pro Endurance SD Card and I switched to MariaDB after initial problems
