Actually, Ninja Blocks' next iteration due toward the end of the year will have onboard RF433Mhz, which allows you to interface with a ton of things you might already have in your house (motion sensors, door bells, door sensors, etc). These devices are super cheap and use crazy small amounts of power.
We've tried to go to great lengths to make it possible for non-hackers to interface with us, for instance you can train the platform what devices are in your house, and then make rules that might trigger anything, such as RF devices like power sockets, Webhooks, SMS, and many more.
Right now we're focussed on getting the rest of our Kickstarter obligations out (we're currently waiting on RF433 dongle's, finally due next week), and are working hard on building a platform that other's can build apps on-top of.
Edit: Don't want to steal SmartThings' thunder here, it looks really cool and we welcome the competition. Just wanted to correct the inaccuracies of the above comment.
