Hue Smart Plug Turn On/Off not working

I found my device on this list: Hue smart plug - deCONZ REST-API
and it also gets recognized, but I am not able to interact with the smart plug. I set up deCONZ today and it works great with my lights but I don’t see any option in the phoscon app to turn the plug on/off. When I press turn off all lights the plugs also stay on.
Any idea? Am I missing something? I didn’t find any solution online.
