Hi Roger et.al, The shutdown /reset of UPS is near instantaneous after rpi reboots or switches off. FWIW -- It looks like something is off with Ubuntu 20.04 -- I tried with raspbian and arch linux using the same nut configuration on the same hardware and the UPS does not reset.
I have repurposed an old rpi2 to act as a nut server. Thanks Roger.
