Harmony 890/890 Pro Z-Wave Intergration

I’m a huge fan of the old school Harmony 890 and 890 Pro remotes… and I’ve been looking for and integration or documentation on how to add it to my Home Assistant Z-Wave network and use it as a scene controller…and add z-wave functions to it’s activities.

Trying to add it as a Z-Wave device, it gets recognized, but never finishes loading the device profile.

Would love to see these remotes supported natively, as I think they are incredibly underrated.
