@Luciano-S. thanks, I have bookmarked that post. I haven't received the Omega2 and I wanted to make sure it was possible to install packages from source even if they are not in opkg list. After reviewing http://repo.onion.io/omega2/packages/ I realized not all packages on wireless---network category are on opkg. I think it should work based on the Octoprint 3D Printer Server Post
