Thats a Z-wave 100 device: https://products.z-wavealliance.org/products/316
It does look like Hubitat added a dedicated driver for it back in 2020, it will probably work on a C5 hub, maybe a C7. If you cannot get it to pair with a C8 easily I would not put much effort into it, those old non-plus 100 devices are a pain even if you do get it paired.
Are you using the RF features of that switch at all or you just want the smart switch part to connect t Hubitat?
For a light switch with button/scene events I would check out the Zooz stuff:
[DRIVER] Zooz ZEN Switches Advanced (and Dimmers)
