Homematic IP Wired Setup and Switch Compatibility

Hi everyone, I’m in the process of setting up my new home and have been working closely with an electrician to ensure everything is properly wired. For each sensor and switch, I’ve installed a 2x2x0.8 EIB cable. Initially, I was leaning towards KNX, but now I’m more inclined towards Homematic IP wired. I need to make a final decision soon.

With a 4-wire EIB line, I can control up to 3 switches. I came across these switches on Voltus.de and am wondering if they are compatible with my setup: Jung Ls403tsaww. I also found these modules: Jung 4212 TSM.

I know about the 6-fach SPS switch blog from smartfabrik and assume that I don’t need the 6er IO module for these switches. Is that correct? My goal is to control lights and blinds with these switches. My trusted electrician is stepping back due to his lack of expertise with KNX and SPS, so I’m on the hunt for someone who can help me set up Homematic IP or KNX.

I prefer not to use wireless switches and have experience with Haus-Bus switches, but I’m leaning towards the Jung program for better compatibility. Any advice or experiences would be greatly appreciated!

Thanks for your help and best regards, Matthias
