@fastfreight here’s a proposed solution…
1. You need to set up LAN with wifi. You don’t need internet for this. You need a wifi router that doesn’t require internet to be setup.
2. hardwire your Moon streamer to thus router
3. Connect your smartphone or tablet to this LAN wifi. You should now be able to control your streamer
4. your library on a hard drive - try copying this library onto an external usb drive that is NTFS formatted. Your moon should be able to read it if the USB port on it is configured to read external drives.
You should be all set.
