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

Unfortunately it doesn't appear to have any effect, ie..
Aug 02 11:34:04 ups1 at localhost upslog[1524] load: 18 temp: NA voltage: 0.0 recharge: 65 frequency: 0.0 status: OB DISCHRG
Aug 02 11:39:04 ups1 at localhost upslog[1524] load: 18 temp: NA voltage: 0.0 recharge: 50 frequency: 0.0 status: OB DISCHRG
Aug 02 11:39:14 ups1 at localhost upslog[1524] load: 18 temp: NA voltage: 0.0 recharge: 50 frequency: 0.0 status: FSD OB DISCHRG LB
Aug 02 11:53:01 ups1 at localhost upslog[1524] load: 17 temp: NA voltage: 225.0 recharge: 8 frequency: 49.0 status: OL CHRG
Aug 02 11:58:01 ups1 at localhost upslog[1524] load: 18 temp: NA voltage: 225.0 recharge: 11 frequency: 50.0 status: OL CHRG

[battery.charge.low]
Remaining battery level when UPS switches to LB (percent)
Type: STRING
Value: 50

[battery.charge.restart]
Minimum battery level for restart after power off (percent)
Type: STRING
Value: 60

[ups.start.auto]
UPS starts when mains is (re)applied
Type: STRING
Value: yes

[ups.start.battery]
Allow to start UPS from battery
Type: STRING
Value: no

[ups.start.reboot]
UPS reboots when power returns during shutdown delay
Type: STRING
Value: no

I have the following ups.conf entry..
[ups1]
        driver = newmge-shut
        port = /dev/cuau1
        ondelay = 190
        offdelay = 120

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.

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.

Unfortunately this UPS is remote so testing it is difficult :(

Any suggestions welcome :)
