Jennic now offers a reduced-complexity network stack called Jen-Net, which has about a third of the memory overhead of Zigbee. Their microcontrollers and modules have both stacks in ROM, and applications can run either. This is something I need to study carefully for the aiosphere, which Jennic looks good for anyway. Here is a cursory overview of Zigbee dev kits, which favors Jennic’s offering. Reading their support forums, though, sugests that all will not be smooth sailing if I select this platform for development. Next stop, Ember.
