Pytomation is an extensible automation system written in Python. It's uses
include home automation and lighting control but is certainly not limited to
those uses. 

It currently runs on Linux, however, it should run on anything Python is supported
for.  It runs well on any version of Raspberry Pi B, B+ or Pi2

Pytomation is well suited to automating your home without having to rely on

mobile apps and web pages.  Walk into a room, the light comes on, leave the
room and the light turns off, possibly after a set time.

Have a light such as the back door come on at 100% and then idle at 40%, after a delay.

Automate your garden as well with digital I/O to monitor moisture levels and

turn sprinklers on or off when appropriate.

Thermostat control is also included as well as almost anything you can communicate with

via a UNIX pipe command.
