I am so excited about homekits, I was going to go for a control4 system to control some home automation in the future and have got myself a few bits to start with till I get the proper install. However I probably won't bother now because I don't think its kinda needed. At present I have sky bell installed, sonos installed in nearly every room and honeywell evohome (here and installation booked). I am looking at my next project to be rako light installation throughout the house. This system that Apple has announced can really move this market in a way that almost the iPad did for the tablet market. Skybell and Honeywell were on the list of companies on board but Hopefully sonos and Rako will also be added. Im sure lutron (light control) and others will follow. Which companies are you excited and hope will join?
