Any ideas please where I can get help with Home Assistant? I have 2 Sonoff Zigbee buttons; one a simple button, the other a 4 button. They were working, but somewhere down the line their button press events disappeared & they're only showing stuff like battery level change events, not button press events. As far as I can see my Home Assistant Green is fully up-to-date, as are the button firmware. Any idea where to go so that I can use a button press to do things again?
