Wouldn’t your problem look like this now:
Small clarification:
When I manipulate the Switches on the [Zigbee2MQTT] interface, all functions work, and all status returns on the Gladys dashboard are correct.
So the problem:
When you manipulate switch L1 on Gladys, lamp L1 turns on and status return on [Zigbee2MQTT] is OK.
When you manipulate switch L2 on Gladys, the switch returns to the Off position and sends button L1 to ON, lamp L1 turns on and the status return [Zigbee2MQTT] acts on L1.
When you act on the Interlock switch on Gladys, it returns to Off and sends button L1 to ON, L1 turns on and the status return [Zigbee2MQTT] acts on L1
Here you go if it can help
