weewx-sdr not storing data packets of WH1080

[Andrea Cecilia]

Hi there,

I'm having troubles with weewx-sdr and Fine Offset WH1080. The problem is very simple: It finds the packets coming from the sensors, but weewx is not creating data packets to store in its database. Here is what I see:

Sep 30 15:27:56 provaSDR weewx[4964]: sdr: MainThread: lines=[]
Sep 30 15:27:59 provaSDR weewx[4964]: sdr: MainThread: lines=[]

Sep 30 15:28:25 provaSDR weewx[4964]: sdr: MainThread: lines=[]

Sep 30 15:28:40 provaSDR weewx[4964]: sdr: MainThread: lines=[]

as you can see, after finding the data packet, it does not create a packet to be stored. What I'm expecting is a string like

packet={'outHumidity': 69.0, 'outTemp': 20.7, ...}

which is not coming out.

my [SDR] section is:

[SDR]

#   This section is for the software-defined radio driver.
    # The driver to use  
        driver = user.sdr
        cmd = rtl_433 -F json -f 868.25M -M utc -G -s 1024k
        path = /usr/local/bin/
        ld_library_ path = /usr/local/lib
       [[sensor_map]]
        windGust = wind_gust.243.FOWH1080Packet
        outBatteryStatus = battery.243.FOWH1080Packet
        rain_total = rain_total.243.FOWH1080Packet
        windSpeed = wind_speed.243.FOWH1080Packet
        windDir = wind_dir.243.FOWH1080Packet
        outHumidity = humidity.243.FOWH1080Packet
        outTemp = temperature.243.FOWH1080Packet

I think there is something wrong in the sensor map, but I can't find what is.

Can you help me?

Thank you

The indentation looks off.

I found these lines from the sdr rpi recipe really helpful:

# see how the sensor data from rtl_433 are mapped to fully-qualified names
sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/sdr.py --cmd="rtl_433 -M utc -F json -G"

# in particular, look at the 'out' and 'parsed' lines like this:
out: ['{"time" : "2019-01-16 11:45:33", "model" : "Acurite tower sensor", "id" : 2453, "sensor_id" : 2453, "channel" : "A", "temperature_C" : 16.700, "humidity" : 31, "battery_low" : 0}\n']
parsed: {'temperature.0995.AcuriteTowerPacket': 16.7, 'dateTime': 1547639133, 'humidity.0995.AcuriteTowerPacket': 31.0, 'status.0995.AcuriteTowerPacket': None, 'battery.0995.AcuriteTowerPacket': 0, 'channel.0995.AcuriteTowerPacket': u'A', 'usUnits': 16}

Can you run the first highlighted command (with the rtl_433 portion reflecting your setup) and see if you get the out: and parsed: lines for the WH1080 device?

your rtl_433 is emitting the format for FOWHx080Packet, not FOWH1080Packet

in your sensor map, change FOWH1080Packet to FOWHx080Packet 

sorry for the confusion - since rtl_433 begain, there have been at least 4 or 5 different formats for the fine offset 1080/2080/3080 data

at some point we should remove the old ones from weewx-sdr, or consolidate them so that they automatically detect the variations
