Hi, any chance to add MIB for Moxa EDS-4012 Series switches?
Software Package for EDS-4000 and EDS-G4000 Series (MIB):

I think you and I are the only LibreNMS Moxa users on the planet 
I’ve added a few over the past while and made some general improvements, but I’m definitely not an expert at it: Pull requests · librenms/librenms · GitHub
I don’t know how to do it reliably without having the device physically available on the network, if you could get it on the Internet and responding to SNMP, I could probably get it added. Each Moxa model (not just family, every model in that family too) has a different MIB, but it’s fairly straight forward to update the relevant files to add new models.
Alternatively if you can generate the test data for it, I know how to use that to test against - but you’d need a development environment of sorts to do that I think, and we’d have to back and forward a bit to update the test data once we have the device detecting fully - would be a little bumpy, but possible if you’re motivated to get them added - what’s your capability to do some mild development work and learn the process with me?
