the weewx-sdr extension maps 'raincounter_raw' to 'rain_counter'. but the
'rain_counter' is a raw value - it has not been converted to the correct
units (in this case, cm since the usUnits is METRIC).
so the sensor map should contain:
rain_total = rain_total.xxxx.Acurite5n1Packet
where xxxx is the sensor identifier (a hex string in the case of acurite
5n1 instruments)
when i first wrote the weewx-sdr driver, the names reported by rtl433 were
all over the place, and most of the sensors had no json output. thus my
attempt to normalize them to something more standard. now that rtl433 has
much more consistent output, it probably makes sense to make weewx-sdr get
out of the way and let the sensor_map do more of the work. maybe that is a
refactoring task to prepare weewx-sdr for a 1.0 release...
for example:
rain_total - total rain count since some reset, in some unit system
(depends on hardware, typically counter wraparound, power cycle, or
daily/monthly/yearly reset)
rain - delta value between two times, typically either loop period or
archive interval
rain_counter - arbitrary counter as number of bucket tips or raindrop
events (depends on hardware)
the raw labels vary a lot, from 'rfa' (HTTP output from LW30x) to
'raincounter_raw' (JSON output from recent rtl433 for acurite 5n1) to
binary values in specific locations (most other hardware).
charlie, sorry that this has been such a goose chase. there are so many
different types of sensors and many of their interfaces have changed over
the past 10 years, so i sometimes get confused between interceptor and sdr
and some of the low-level protocol naming conventions. when in doubt, look
at the code! :)
if you could post the output from running weewx-sdr directly, that would
clarify a lot.
sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/sdr.py
--cmd="rtl_433 -M UTC -F json -G -vv"
note that the 'cmd' should match whatever you have in your weewx
configuration file, otherwise you are testing apples while running oranges.
