Anyway to auto-delete devices??

So, im using an app called DarwiinRemote that lets me control my Mac with the Nintendo Wii remote. Its great, but for some reason after I exit the app & then try to re-sync it, it doesnt work. I have to manually go to my bluetooth preferences & delete the Wii remote from my device panel, which is starting to be a pain. And I cant just leave the app running because then the Wii remote stays powered on & never sleeps, which kills the battery.

I know this is something that the app developers need to fix, but is there a way to auto-delete items in the device panel afterwards??

Im sure there is a terminal command or script that will do this, but I suck at those 2 things.
