HA Platform
The core of our HA installation is Misterhouse. For those not familiar with Misterhouse it is a mature, comprehensive and extensible solution written largely in Perl. There is an active global user community and helpful mailing list etc. The active development code is now on github.
We also use Heyu to interface to other RF devices such as power monitors, Oregon Temp/Humidity sensors.
