Does your UPS not measure the volts and allow you to poll it for that
information?

You leave it plugged in, it counts the number of transients, and has
LEDs to indicate if the voltage has been out of range (mine's the old
240V +/- 6%, presume they are now calibrated for 230V +/- 10%)

Shouldn't be the spec never actually changed to +/- 10%. It's still
230 V +10% -6% (216 - 253 V).
