Nut upsuser - Feb 2014 - How do I initiate a shutdown sequence immediately after losing line power?

Hi! 

Is there a way to tell upsd to initiate a shutdown sequence (i.e. run
SHUTDOWNCMD) immediately after losing line power and switching the state
to OB? 

I'm using an old battery and by the time it reaches LB state, it's
already too late for a clean shutdown. 

Another solution would be to change the LB percentage. It currently
reads (upsc): 

battery.charge.low: 10 

Is there a way to raise that to, say, 40 or 50 percent? 

The goal is to initiate she shutdown procedure as soon after losing line
power as possible. 

Thanks!

A generic way would be to have upsmon signal upssched, and run the shutdown
command when upssched gets the OB signal:

You may want to look at the timers in upssched; otherwise, you may get false
positives if your UPS briefly transitions to OB during a power
glitch.

Hard to say without knowing what driver you are using (and even then, it depends
on the UPS firmware). But if that variable shows up in the list when you run
upsrw, then you should be able to adjust it.

Using the upsrw command I was able to change the value of
battery.charge.low from 10 to 40, so my problem is solved for now (at
least temporarily, until I get my battery replaced). 

Thanks a lot for your help and have a nice day!
