offdelay=num

Change shutdown delay time from 0 second default​.

Instant Commands

This driver supports the following Instant Commands​. (See upscmd(8))

All UPS units

shutdown​.return

Turn off the load possibly after a delay and return when power is back​.

shutdown​.stop

Writable Variables

See upsrw(8) to see what variables are writable for the UPS​.

Note

If your UPS supports writing battery​.runtime​.low, the new set value is to be entered in minutes (up to 99) but the reported value is reported in seconds (set value * 60)​.

Note

If your UPS supports input​.transfer​.low and input​.transfer​.high, those values are used to create an allowable output range​. The UPS will do what it can to keep the output voltage value within the defined range (for example: tap change or switch to inverter)​.
