Cool, that's what I was wondering, without being bothered to test my theory
I know there are some peculiarities in the way devices are exposed to / accepted by GH, which in part justifies the need for a Community App to shoe-horn some device-types into what GH is prepared to accept.
For the time being that may be where you need to look @waterboysh, the Community solution until something can be done for these activators... No promises (from me) that is will work, but worth a look....
