Zooz ZEN37 800LR won't create device

I am struggling with Minoston MR40Z (cousin device to the ZEN37).
C8 Pro migrated from C7
Platform 2.4.2.134

Tried smartstart (S2 and LR) first. It hung up for hours and I observed various hub messages about failing to include.

I tried the method above. It took hours, but indicates that it was included. I tested various drivers without any response to physical button presses (Generic Z-Wave Button Controller - standard and Plus, community Minoston Wallmote, community ZEN37). So, I excluded again.

I setup SmartStart Manager and disabled the device. Factory reset. Shutdown and restart hub. Re-enable. Here I am stuck at pending again.
