I am seeing a sync issue with an intermatic relay power switch. I am able to include the device by the manual z-stick button include process. It shows at address 34. When I try to sync to the device called Air Compressor I get a fail. I am doubtful its an out of range issue. This device was functioning correctly with my old Z-Stick Gen 5, I upgraded to the Z-Stick Gen 5 plus and am unable to sync with the new stick. I was able to remove and sync every other Z-Wave device without issue.
