all added via zigbee2mqtt, all on current firmware, and all are set to do basic on/off controls via bind for a bulb (or group) in the room they are in.
i have found that 2 of the switches (bedroom and livingroom), when turning on or off light, don’t update the HA overview/dashboard screen to show that the light has changed state, the other 3 don’t have this issue.
this means that we have a light on (triggered via the dimmer switch) but the HA dashboard says it’s off (and vice versa). all the bulbs and switches have been set up identical so no idea why 2 are behaving like this.
ok well either way the state is not being updated when i use the dimmer switches.
the state gets updated when other methods are used - ie direct from dashboard or via HomeKit.
i’ve moved the switches over to being configured with “switch manager integration” which seems to have resolved the problem, still not sure what caused the original issue though.
