Well, a guy named Jerome on another thread in RTL_433 figured out the lightning bits - https://groups.google.com/forum/#!topic/rtl_433/gvTUFWJlFxE so I am not so sure it isn't NOT understood anymore. This was all within the last month or so.
The problem is that the Acurite equipment keeps transmitting the same last value for lightning, both strikes and distance....same as it does, essentially for rain (Atlas & 5n1). The rain and strikes are easy enough to calculate using options within the WEEWX.CONFIG file under the deltas section of the SDR configuration. The lightning distance isn't so easy... that is why I am saying we need something equivalent, but obviously not a delta calculation. I see your point about using null instead of zero....zero could mean that the storm is literally right on top of me. :-) In any case, it would be nice if we could get that into either the logic for the "ACURITE.C" for RTL_433 file or into "SDY.PY" file for weewx-sdr. :-) On Saturday, April 25, 2020 at 12:31:29 PM UTC-4, Greg Troxel wrote: > > Chris Morris <[email protected] <javascript:>> writes: > > > So, lemme take a stab at explaining in a somewhat Boolean way... > > > > If strike_count_total_current = strike_count_total_last, then set > > strike_distance = 0, else strike_distance = INTEGER (actual value > > reported by Atlas or 6045). > > Really if the current/last counts are equal, strike_distance should be > omitted, or it should be set to some sort of nil or undefined value. > It is not actually 0 either. > > Then, the bits output by the acurite for distance, are not actually km > or miles.
