There is only one problem with it and that is when you edit the ozwcp Makefile, it’s currently setup for MAC and there are some lines you need to comment out and a couple you need to un-comment. They are documented in the file, and someone had a problem with it and the answer is in the comments down below.
I think it’s just part of the install now. No longer any need to shut down HA and start OZWCP. Just go to the zwave menu option in the menu on the left. Works great for me.
