I came across an article recently on how to set up a simple Home Automation system using a Raspberry Pi with an RF transmitter attached to it, and node.js with Angular.js.

It’s fairly primitive in that it is mainly a web interface to some light switches, but has the potential to grow into a real automation system. Keep an eye out for new releases (the author, Dennis Schulte, has given it version number 1.0, since the system is in production! 🙂
