The counters are cumulative, and that is inherent to the hardware. (It's a
security feature, I believe.)
The simplest solution is just to do the subtraction in your program. We
could also do it in OWFS.
Louis Swart's LCD has counters that are reset by reading, so there is a
stored cumulative property that gets updated every read and can be set with
a write. We could do something like that for the DS2423 if there is
sufficient interest.

Hi everyone,
I've got a DS2423 counter monitoring my electricity meter,
it counts the pulses that are captured by an IR
photo sensor directed at the rotating dial of the meter
(which is reflecting with one non-reflecting marker
per rotation).
I would like to reset the DS2423 counter to zero sometimes.
Is it possible to set its counters to 0 via the 1wire bus?
Changing the values in the pages of the chip (in the owhttpd web
frontend) does not change anything. Cutting power to the
chip is no good solution either.
Thanks,
Philipp
