Hello,
I just bought a Iluminize 511.012 https://www.iluminize.com/de/shop/led-steuerung/led-controller/product/520-511-012-zigbee-controller-8a.html
The controller has the ability, to connect to a momentary switch. When the switch is pressed, the controller does not report its state. That is a normal behaviour.
The manufacturer said to me, that the bridge is constantly asking for the state every 30 seconds. So latest after 30 seconds, the bridge knows the state.
But how can HASS ask for the state?
I use zigbee2mqtt.
