Hey,
I have six ceiling spot lights (IKEA Tradfri GU10) in my bedroom. Whenever I occasionally check them when I come home I find three of them (they are indeed grouped) on. I have checked all automations, scripts and scenes if they are included somewhere but they are not. Also they are shown as off on the Dashboard when they are on. I can use them normally via the Dashboard.
I assume they are getting a wrong signal from the coordinator.
I use Zigbee2MQTT.
My question is, is there an option to check what gives them the command to turn on?
