Philips Hue lighting system allows you control lights wirelessly via the accompanying Hue app. You can not only switch lights on/off, but also change the color to suit your mood or the room color. You can also connect it to IFTTT to setup cool rules, for example change the Philips Hue bulb’s light shade to blue if temperature outside falls below 20°. There are multiple options available – you can buy either a starter kit or a standalone bulb. The kit comes with a bridge to connect to your Wi-Fi router and allows you to control the light even if you are away from home.
