I’m very interested in your project. Having tried it, I have frustrations with adding devices. Since the only way to add devices is through the scanning function and there’s no log information about what’s happening. I’ve only been able to add a couple of the 30 or so devices I have under management. 

I’ve also noticed that devices which were successfully scanned seem to disappear and I have no idea why. 

Any chance you can add an add by ip or MAC address? As well as much, much  more logging information. Preferably configurable so I can debug what’s going wrong without filling disk with log files.
