I didn’t find you until now and I’ve already started on a sensor project based on the programmable XBee Pro from Digi. Mostly door temperature, door, and light sensors for now. I’d love to fold it under SmartThings umbrella since Z-wave has some great GE items and I’d love to focus on HW (I do SW at work and that’s enough). So I’ve been browsing around the site but I can’t find the DevKit link or even the ZigBee frame definition. Are you under HA or something else?
