My good friend Tim Richardson has been experimenting with the Philips Hue range of connected lights. He’s got a set out in his shed Cabin and he wanted them to be controlled remotely from another Raspberry Pi (primarily so that people in the main house could ‘call him in’). He struck upon the idea of using a Pimoroni Touch pHat in the main house so that different colours were triggered in the Cabin when the buttons were pressed. This gives granularity over how urgent the ‘call’ is. He’s used and adapted the phue library and developed some custom scripts. All the instructions, and the code, are available on Github. You can get hold of Hues by doing a quick search on Amazon! They’re not cheap, but they’re great fun 🙂
