In case somebody is looking for DIY inspiration
I have lately spending my free time on developing a few interfaces using Arduino to communicate with Zipato. I know, Raspberry Pi would be "easier" but I think it is too expensive for what I want to achieve.
While I get my Z-Uno (arduino with Z-wave chip), I have been playing with with my YUN and UNO + Xbee SB6 Wifi shield, and while looking for references I found this YouTube Channel and web pages, this guy is a master in electronics and he has built is home automation system entirely using OpenHab and POE arduinos, if someone is looking for some DYI inspiration and reference take a look below, he not just sells the boards and electronics but he shares the electronic and PCB design in case you want to build your own. He got to the extreme of self-implanting an RF-ID device on his arm in order to use his arm in his home automation system
I think is well worth to share;
