I have no clue! I had no intention of using their Nexia service, instead using my Vera Lite from Mi Casa Verde as my Z-Wave hub. It's far more powerful and has a pretty active online community, including professional home automation installers.

I've been spending the whole day wiring in the second batch of ZWave wall switches. I now have almost one entire floor outfitted with ZWave control. There's a couple more lights on the main floor I want to add, then about four in our basement and 6-8 on the second floor. I already have over a dozen lamp modules, so I'm pretty set there.
