EU/UK C5 Z-Wave Failing

[rebecca]

I've so far semi-followed this guide on Simplicity Studio 4

Need help with with Z-Wave problems on a C-5

I was thinking of updating to the C7, but I'm not sure whether to stay with Hubitat, I like everything in 1 place, if I could get calendar events notifications sorted, using my Caldav Calendar, and be able to talk to and send to google home, i would definitely stay with hubitat and upgrade, but at the moment I have to use RPi4 with node red, so do I use my RPi4 and install Home Assistance or upgrade to the C7. How would you do the Z-Wave secondary controller.
