I have 12 of these paired and integrated, so they definitely work. They were also on hub v1 and I moved them to hub v2 without issue. I also paired many of them pretty far away from the hub, but my mesh is large.
Repairing your zwave network doesn’t do anything for you, so let’s check a few things. Please confirm your exclusion/inclusion process:
First put the hub in exclude mode, and then you slid out the battery compartment, and then slid it back while pressing and holding down the Test button until you heard a beep? When you excluded the device, did the app confirm “a device was excluded”?
After successfully excluding the device, you went back to the app and went to include the device via Connect New Device (verify the hub is in include mode by visibly looking for the blinking green light), and while holding down the Test button you slid the battery compartment back in until you heard a beep?
