I've been tinkering with my new house for 3 years now. I've got a load of LightwaveRF dimmers and switches all over the house. And I custom (over) installed my own DSC Power Series alarm system. I've added an underground irrigation system, HD IP CCTV cameras and a Nest thermostat. So now I'm in the process of getting all this stuff working together. That is when I stumbled upon openHAB!
