Anyway to port a Smarthings or Hubitat plugin - Kevo Plus

Good morning all,
I have two Kevo smart locks on my home, along with the Kevo Plus gateway. I’ve been wanting to integrate with Vera for a number of years, however, Kevo’s API is closed, and I’ve never seen anything on this forum regarding integration.

I came across a thread on Hubitat’s community forum where someone had developed an unofficial app/plugin for Smarthings, and then someone else ported it to Hubitat.

SmartThings unofficial Kevo
Hubitat Kevo

I’ve never done any Vera plugin development. What would be involved in porting this app?
