Monitoring a UPS. I recently put a garage RaspberryPi on an APC UPS and was having trouble using the USB cable to monitor it. Fortunately I had some downtime where I could power off the Pi (I built a box with fans to house it) and after a "reboot" of the UPS the apcupsd software worked fine. The garage system is a Pi4 with a couple of external hard drives attached to be used as a backup system (drives are encrypted as well so if someone swipes the whole thing all they get is hardware...)     #>
