as stated in the description, you must go through a "power off" or status
off, for this to work
Ie, once you reach "FSD OB LB", the shutoff (UPS poweroff) command must be
applied to the UPS.
once off, and the power is back, it will wait for battery.charge.restart
level to be reached before reapplying power to its output.
for manual / unit testing, you must issue an "upscmd ... load.off |
shutdown.return" or equivalent, to get the OFF ups.status

isn't 'upsdrvctl shutdown' called around the end of the halt script, once
HD are in RO mode, or just before?

hope it helps.
