Back in January, a smart home device called Ninja Sphere made over $650,000 on Kickstarter. Now, its creators (Ninjablocks) has started accepting its first pre-orders outside the crowdfunding website for $329 per unit. But, what can a Ninja Sphere do in the first place? Well, this gesture-controlled device can monitor temperature, lighting and even energy usage, but that's just one of the things it's capable of. Ninjablocks touts it as a veritable multi-tasker that sends alerts if you've left appliances running when you go out and let you turn them off using your phone. With the proper IFTT recipes in place, it also lets you switch on the heater or AC before you get home, or switch on the lights at a set time using a phone or even a smartwatch.
