The hsm100 return four states, Temp, Light, Movement and its own battery level. In Homeseer these are seen as four separate devices. The idea was that I would use the light level and temperature to set the home cinema environmental and lighting levels.
The Nevo does not seem to have the requisite widgets to allow this and also only seems to see one device on pairing. I can now do this through Homeseer (thanks Eric) but it would have been nice to use the if..then options on the remote.
