Isn’t it too early for copycat products? http://revolv.com/
The biggest negative right now: $299 for the hub. Compare with this SmartThings retail packages:
$199 = Hub + Multi + Presence + Motion
$299 = Hub + Outlet + 2x Multi + 2x Presence + Motion
The other question if of course the development interface. Will it be as powerful as SmartThings?
Definitely has Z-wave and as some network interface (can control Hue Hub). Not sure on Zigbee though they say they want to be compatible with all off the shelf products.
