Moving to Hassio supervisor - supporting LiFePo4wered/Pi+ UPS

I am currently running “Home Assistant Supervised” on a Raspbian powered Pi 3B+. I have stayed using this approach because all my critical PI’s have a LiFePO4wered/Pi+ UPS to protect them from power problems. The UPS is brilliant, but it needs a system daemon to monitor it and perform an orderly shutdown if the battery gets low (or however you have configured the UPS). The daemon is written in c++ and c, so I’ve left it as-is.

It’s clear that “HA Supervised” is discouraged so I want to move to Home Assistant. BUT…

Given that “Home Assistant” runs on Alpine, is anybody else using this UPS, and have they successfully migrated the daemon?
