Z-Wave Devices w/ Missing or Incomplete Drivers

Sorry, new here (from smartthings), but I've got an issue with a "critical" zigbee device which has a functional driver for smartthings, but the attempted port to hubitat doesn't work.

Where would be the best place to attempt to beg for someone knowlegable to successfully convert please? For reference, thread is here (Drayton Wiser Heating - port from ST?)
