One day, I’ll get round to writing this up in more detail. Frustrated at the lack of integration between existing products, I built my own home automation system.
It runs on a Raspberry Pi, using event-driven javascript (node.js) and wireless mesh networking (xbee) to link various bits of my house together, and connect them to the outside world.
I can, from any browser:
The system can log things like the doors opening or the power use/temperature into a database.
I open-sourced some of the node.js and xbee code, and it’s grown into a little project of its own.
