Fineoffset-WHx080 and SDR sensor_map

[Michael Jackson]

I'm having some trouble mapping the sensors from my FineOffset WH1081PC via rtl_433 and weewx.  I can get the humidity and temperature but can't seem to map wind, wind direction and rain.

This is the return from xxxxx:

[u'{"time" : "2020-02-29 06:46:12", "model" : "Fineoffset-WHx080", "subtype" : 0, "id" : 104, "battery_ok" : 1, "temperature_C" : 18.200, "humidity" : 63, "wind_dir_deg" : 203, "wind_avg_km_h" : 4.896, "wind_max_km_h" : 7.344, "rain_mm" : 924.300, "mic" : "CRC"}\n', u'{"time" : "2020-02-29 06:46:13", "model" : "Fineoffset-WHx080", "subtype" : 0, "id" : 104, "battery_ok" : 1, "temperature_C" : 18.200, "humidity" : 63, "wind_dir_deg" : 203, "wind_avg_km_h" : 4.896, "wind_max_km_h" : 7.344, "rain_mm" : 924.300, "mic" : "CRC"}\n']

and this is what I have mapped so far:

outTemp = temperature.*.FOWHx080Packet

windSpeed = wind_avg_km_h.*.FOWHx080Packet

windDir = wind_dir_deg.*.FOWHx080Packet

outHumidity = humidity.*.FOWHx080Packet

rain = rain_mm.*.FOWHx080Packet

Should I be editing sdr.py with the results from rtl_433 for the FOWHx080Packet?

it looks like you are getting a "new style" model key ("Fineoffset-WHx080") instead of the "old style" model key ("Fine Offset Electronics WH1080/WH3080 Weather Stations")

please post:

* the version/release/package of rtl_433 that you are using

* the command you use to invoke rtl_433

* the [SDR] section of your weewx configuration file

Output from rtl_433 -V:

        windSpeed = wind_speed.*.FOWHx080Packet

        windDir = wind_dir_deg.*.FOWHx080Packet

        outHumidity = humidity.*.FOWHx080Packet

        rain = rain.*.FOWHx080Packet

Thanks for looking into this Max.

thanks for that.  i will probably have to start supporting both new style and old style model strings.  sigh.

could you confirm by posting the output from running sdr.py directly?  (see the instructions in the weewx-sdr readme)

5-10 lines of sensor data should do

Well, the output of sdr.py using the string in the readme (sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/sdr.py --cmd="rtl_433 -M utc -F json") gives this

Thanks again for any insights.

OK, I have the syntax now for what's in sdr.py and mapping sensors to a particular model and have managed to get all the available sensors reporting to the database and html reports, happy days!
