Tradfri OnOFF Switch - why 2 messages sent when clicked (?)

Hi, does anyone know why the server sends two messages when i press ON or OFF, this irritates Openhab a lot and i do not see the use for this…

I think it’s the same as with Xiaomi wireless switch. It’s “expected behavior” when home assistant integration is enabled. More information here:
