I was trying to make my own cape for a Pi which could connect to the Multiplus-II, and while the hardware for VE.Bus (as seen in the nanopi GX for eg) is quite trivial, I found out mk2-dbus is closed source as also the settings file (eg /data/var/lib/mk2-dbus/mkxport-ttyS3.settings).
Is there any plans to change this to allow for further integration of custom solutions?
