Hello

i have a hue dimmer switch v2, a slzb 06, and zigbee2mqtt

when i bind the switch it’s working.

the on button works, the dimmer work, the hue button doesn’t do anything which is normal. But i can’t switch off the group of light. Only the ON works

i tried with legacy_action_sensor true and false but not working
