I installed my new Almond 2015 as a router and installed a GE Smart Switch (Zigbee) successfully.
I first installed the Almond connected via wifi to my main router.
I then installed the GE Smart Switch (45856GE with Zigbee $49 @ Lowes) and a GE Add-on switch (12723 Lowes $24).
The Almond didn't see the Smart Switch when "Add Device" on the touch screen and I went to "Zigbee"
I turned the breaker off to the light switch, counted to 10, turned power on and walked (quickly) to the Almond.
It was adding the device. voila' (wallah)
