This 'bug' has been around for a while so I thought I would bring it up; not really bad just misdirecting.
I often get unrelated pistons, like the one below, saying it is in use buy a clearly incorrect piston.
My car beacon certainly doesn't use my blinds. 
I often get my Blink camera routines also listed for an unrelated device.
I can cure this by deleting the piston or device and re-adding it but that's a pain.
I think these are vestiges of a prior life and the code that creates these lists doesn't clear/cull the non-related devices.
