Check the output of "upsrw <ups>" to see if that variable is supported with your combination of UPS and driver.<br>

[battery.charge.low]<br>
Remaining battery level when UPS switches to LB (percent)<br>
Type: STRING<br>
Value: 50<br>
<br>
[battery.charge.restart]<br>
Minimum battery level for restart after power off (percent)<br>
Type: STRING<br>
Value: 60<br></blockquote><div><br>as stated in the description, you must go through a "power off" or status off, for this to work<br>Ie, once you reach "FSD OB LB", the shutoff (UPS poweroff) command must be applied to the UPS.<br>
once off, and the power is back, it will wait for battery.charge.restart level to be reached before reapplying power to its output.<br>for manual / unit testing, you must issue an "upscmd ... load.off | shutdown.return" or equivalent, to get the OFF ups.status<br>

I have the following ups.conf entry..<br>

driver = newmge-shut<br>
port = /dev/cuau1<br>
ondelay = 190<br>
offdelay = 120<br>
<br>
The delay is because I am using FreeBSD and it does not remount the disks read only - the shutdown script calls 'upsdrvctl sutdown' when everything is still mounted read/write.<br></blockquote><div><br>isn't 'upsdrvctl shutdown' called around the end of the halt script, once HD are in RO mode, or just before?<br>
</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
I added some debugging to my shutdown script and upsdrvctl is exiting with a 0 code so I think it's doing the right thing.<br>
<br>
Unfortunately this UPS is remote so testing it is difficult :(<br>
<br>
Any suggestions welcome :)<br></blockquote></div><br>hope it helps.<br><br>cheers,<br clear="all">Arnaud<br>-- <br>Linux / Unix / Opensource Engineering Expert - Eaton - <a href="http://opensource.eaton.com" target="_blank">http://opensource.eaton.com</a><br>
