Trying to add Simon 100 Devices

Hi, just moved to a new home and the builder put a bunch of Simon 100 switches.
Mostly light switches, Blind up/down and a couple of Hub Pros.
The Simon App is kinda crappy and slow, and it seems like the hubs dont cover the entire house properly.

I am pretty new to smart home things and trying to learn…

I have Home Assistant yellow POE with CM4 8gb RAM and 32gb flash storage.
My main systems at home are Apple HomeKit, since I already had many of apple devices in the house.
I also have an Habitat C8pro but I haven’t used it yet, was thinking to use it as some kind of bridge or antenna as I’ve seen many people saying it has a strong Z-Wave antennas, since SimonIO uses Z-wave plus, I thought it might be handy… but I am open to get something better if needed.

The end goal is to make a nice dashboard using the existing Simon tech and slowly add sensors and other stuff like Unify protect, Aqara sensors(open to suggestions) etc.

Thank you for your time and help <3
