Note

When a user reports that a variable/command is not right then it will be highlighted by a red underline.

Bad values/ranges/etc… will get a red dashed outline or red solid left border.

The accompanying explaining comment - if provided - will be emphasized through a red dotted border on the left.

About this device

This device doesn’t report the correct output voltage when the voltage selector, the one under the device, is set to 220V. It keeps showing the outpout around 110V. The manufacturer won’t fix that because the place where the voltage is measured is before the switch in the circuit. Device dump generated by ./nut-ddl-dump.sh on Tue, 21 Jul 2026 14:07:02 -0300

Further system data or configuration examples:

Variables per upsrw tsshara@localhost listing
# TODO: Convert to RW:... and RO:... markup
:; upsrw tsshara@localhost
[driver.debug]
Current debug verbosity level of the driver program
Type: NUMBER
Value: 0

[driver.flag.allow_killpower]
Safety flip-switch to allow the driver daemon to send UPS shutdown command (accessible via driver.killpower)
Type: NUMBER
Value: 0

[ups.delay.shutdown]
Interval to wait after shutdown with delay command (seconds)
Type: RANGE NUMBER
Option: "12-600" SELECTED

[ups.delay.start]
Interval to wait before (re)starting the load (seconds)
Type: RANGE NUMBER
Option: "0-599940" SELECTED
Commands per upscmd -l tsshara@localhost listing
# TODO: Convert to CMD:... markup
:; upscmd -l tsshara@localhost
Instant commands supported on UPS [tsshara]:

beeper.toggle - Toggle the UPS beeper
driver.killpower - Tell the driver daemon to initiate UPS shutdown; should be unlocked with driver.flag.allow_killpower option or variable setting
driver.reload - Reload running driver configuration from the file system (only works for changes in some options)
driver.reload-or-error - Reload running driver configuration from the file system (only works for changes in some options); return an error if something changed and could not be applied live (so the caller can restart it with new options)
driver.reload-or-exit - Reload running driver configuration from the file system (only works for changes in some options); exit the running driver if something changed and could not be applied live (so service management framework can restart it with new options)
load.off - Turn off the load immediately
load.on - Turn on the load immediately
shutdown.default - Run the driver-defined UPS shutdown sequence (as opposed to user-configured 'sdcommands')
shutdown.return - Turn off the load and return when power is back
shutdown.stayoff - Turn off the load and remain off
shutdown.stop - Stop a shutdown in progress
test.battery.start - Start a battery test
test.battery.start.deep - Start a deep battery test
test.battery.start.quick - Start a quick battery test
test.battery.stop - Stop the battery test
