Note that only a handful variables (mostly related to critical
ups.status flags) will be polled every 'pollinterval' (default: 2)
seconds (for the mge-hid subdriver) and the remainder of the variables
only once every 'pollfreq' (default: 30) seconds. See 'man 5 ups.conf'
and 'man 8 usbhid-ups' respectively. So with the 'pollonly' flag set,
the OL/OB/LB and *.timer variables will be updated every 2 seconds and
the remainder every 30 seconds.
Best regards, Arjen
