Saw your other thread discussing HAL - is your current setup using NUT
to determine when to shut down, or is NUT just telling another
subsystem when the UPS is on battery power (which might just use a
timer, instead of waiting for a low battery condition)?

What about variables?


$ upsrw mge1200 at localhost

The "battery.charge.low" might be set to a high percentage.
