I am starting to study and work on home automation using Xbee Zigbee modules and PIC microcontrollers. I’m very interested in a standards-based implementation, so I want to use the Home Automation profile. I also want to use PICs since I have years of experience with them and have all the development tools.
I don’t know much about the HA profile yet, so excuse my ignorance.
The hardware is simple. Just connect the PIC to the Xbee with the USART. Done that.
I would like to pull the HA profile code into my PIC project and add some (unknown at this point) interface code that ties the HA profile to the Xbee module (and hence the Zigbee stack) using the USART. Does this interface code exist? I’m not able to Google anything.
TIA,
BRW
HA (home automation) profile of ZigBee… isn’t that licensed by the ZigBee Alliance, copyright, blah blah?
Most all hobbyists don’t use ZigBee, just 802.15.4, since meshing is not needed, or static routing does fine among routers.

Zigbee and Zigbee HA require Zigbee Alliance membership to sell products using them, but are free for non-commercial use.
You say meshing is not needed. Perhaps. But I desire to have a self-healing redundant mesh wireless network (zigbee) for home automation. I want the increased network reliability and range that this provides. 802.15.4 only provides point-to-point or point-to-multipoint communication.

Great! Home-brew. You probably know that due to ZigBee being tardy, Zensys/Z-Wave dominates the home automation wireless mesh market. See Homeseer.com's forums on that.
But it would be great if a dozen or more hobbyists could build a good mesh, perhaps starting with 802.15.5 atop 802.15.4. The issue in such meshes is time-synching the routers that are battery powered. Zensys, Dust, Ember and others have proprietary methods to do this. The 802.15.5 standard is non-proprietary but has not been fully implemented. Another dimension to this problem is home automation controllers that are not UL certified, i.e., are home-made. If your house burns, the Insurance company may well have an out.
