LIFX bulbs are great, but when you just need to turn them on, off or just change brightness, it can be not very comfortable, to do this simple task by app. So I decided to create much simpler way to do this. And then I came across NodeMCU, small development board similar to Arduino with integrated Wi-Fi, with cost of about $5.
