as greg suggested, please check the raw output from rtl_433 to where the 24
is coming from.

its been awhile, but i'm pretty sure the 06045M reports a cumulative value
for strikes. i'm not sure when it wraps/resets.
the weewx-sdr driver will do delta calculations to convert a cumulative
value (count since last reset/wraparound) to a delta value (count since
last packet). the build-in definition looks like this:
[[deltas]]
rain: rain_total
strikes: strikes_total
so if you have this mapping:
[SDR]
...
[[sensor_map]]
...
strikes_total = strikes_total.00E7.AcuriteLightningPacket
then the observation 'strikes' will have the delta value and
'strikes_total' will have the cumulative value.
or you can do this:
[SDR]
...
[[deltas]]
lightning_strikes = lightning_strikes_total
if you prefer to use the name 'lightning_strikes' instead of 'strikes'
of course, all of that assumes the sensor is sending sane data, and that
rtl_433 is not doing any other manipulations.
