I know I'm dragging up an old thread but it's pretty on-target with what I'm working on. I also figured that anybody searching for keywords in this thread would appreciate knowing more about this:
I bought the Lutron "Connected Bulb Remote" today at Home Depot (
http://www.homedepot.com/p/Lutron-Connected-Bulb-Remote-LZL-4B-WH-L01/206196450), which appears to be a version of the Pico style remote, but with Zigbee support included in the device. It has the same form factor as the other Picos, which would make this remote very convenient for installing into standard decora-style switch cover locations (with the available adapter, etc).
It was easily able to pair the remote with the A+, however my hub (which is on r80 currently) reports that the connected device has as status of "Unsupported Device!"
I'm hopeful that this device is on the radar of Securifi's development team, as it has a super handy form-factor and is of reasonable cost/availability (~$30 at time of this post).
Thanks for all of your hard work - I'll hang-up and listen!
