Finally received the Digi USB stick. mapped my zigbee mesh finally and found 8 unresponsive device (routers) . All 8 are GE OUTLINK OUTLET. To the garbage they go I guess.
It's so nice having the tool to map both zigbee and zwave mesh. Finally figured out which devices problematic.
It's the only reason why I still have Wink 2 hub around. I have pretty much my whole house full of GE outlink outlets and can't justify trashing them out. No problem on Wink 2 at all.
