Here's where the MoPi2 hot-swap power supply hat really shines. It takes two 6-30VDC inputs, plus a charge input. Normally, your primary power goes into port 1 and your backup battery goes to port 2.

Pardon my ignorance. You have a local network within your house with just your stuff on it. You have the Macs in your shack and the RPi in the garage. The Macs are on Ethernet and the RPi is wireless.
