Device didn´t work after re-integration

Hi,

I integrated a wall plug with deconz. I see it also in HA and can power on an off. Everything good.
Unfortunately I deleted it in deconz and integrate it new. Now I can see the plug in ha under devices, but I can´t plug on or off. The errormessage is: Error calling the service switch/turn_on. /lights/30 resource, /lights/30, not available.
I think the entity is the old entry and not the new one.
How can I change that?
