Was this stick used previously (either by you or maybe a used purchase?). I had a backup zwave stick that I was playing around with today and it was giving me tons of trouble with inclusion failing until I factory reset the stick. It had a previous configuration on it from when I was messing around w/ it years ago. Once I removed all the associated nodes w/ a zwave config utility (z-wave pc controller that I found online), everything worked fine.
I don’t know if that’s your issue, but I had the exact same problems and the reset resolved everything for me.
hey @breakthestatic - thanks for your reply.
The stick was brand new. After a few more resets of the sticks and hard reboot of my pi, things seem to start working. How odd
I had exactly the same issue to start with. For me, it was an old stick but I had already factory reset it before using it with HA. I have HA OS running in a VirtualBox machine on a Mac and I tried to reboot the HA VM to try to fix the issue but then the VM wouldn’t boot. So I rebooted the Mac itself and that seemed to fix it. VM now boots and I successfully included a ZWave node. Very odd.
