Mi Casa Verde has had the Vera appliance for a number of years. Recently, they released the Vera 3, which controls practically any Z-wave device ever made (in fact many are guaranteed to work). The Vera 3 is also wireless (802.11), so you can place it practically anywhere in the home.
Now there’s Vera Light, which retails for $100 less, has a much smaller footprint and no 802.11 networking but otherwise it appears to have pretty much the same feature set. I’m sure it can’t control as many things concurrently, given the smaller footprint, but it looks to me like a great deal for those looking to get started with Z-Wave and home automation in general!
