I got the reply from APC support in germany
"Power Chute Software does not offer this option and there is no
support for third party software."
(who would have thought otherwise :-)
So it seems the solution is either to set the battery.charge.low each
time (no problem), and/or to override the setting as you suggested (no
Your suggestion made me actually read
again, and I think I was under the wrong impression that it is the UPS
which powers down when reaching battery.charge.low.
Instead it is the NUT tools in some way or other which finally executes
"upsdrvctl shutdown" in /etc/init.d/nut-server. Though I don't fully
understand how the 'poweroff' branch in these scripts is reached
(since I thought they were all called with either 'start' or 'stop'
from 'init'), but as "it works" I probably don't need to care :-)
Case closed, thanks!
