Problems with SDR driver failure to start process.

[weather list]

Running RTL_433 manually outputs:

time      : 2020-06-11 14:09:10

model     : Ambient Weather F007TH Thermo-Hygrometer                         House Code: 175           Channel   : 1             Battery   : OK            Temperature: 89.3 F

Humidity  : 41 %         Integrity : CRC

Running  sudo PYTHONPATH=bin python bin/user/sdr.py the F007TH is not parsed:

out:[u'{"time" : "2020-06-11 18:16:14", "model" : "Ambient Weather F007TH Thermo-Hygrometer", "device" : 175, "channel" : 1, "battery" : "OK", "temperature_F" : 89.300, "humidity" : 41, "mic" : "CRC"}\n']

sdr.py has a parser for the AmbientF007TH:

class AmbientF007THPacket(Packet):

    # 2017-01-21 18:17:16 : Ambient Weather F007TH Thermo-Hygrometer

    # House Code: 80

    # Channel: 1

    # Temperature: 61.8

    # Humidity: 13 %

#    IDENTIFIER = "Ambient Weather F007TH Thermo-Hygrometer"

    IDENTIFIER = "Ambientweather-F007TH"

    PARSEINFO = {

        'House Code': ['house_code', None, lambda x: int(x)],

        'Channel': ['channel', None, lambda x: int(x)],

        'Temperature': [

            'temperature', re.compile('([\d.-]+) F'), lambda x: float(x)],

        'Humidity': ['humidity', re.compile('([\d.]+) %'), lambda x: float(x)]}

    @staticmethod

    def parse_text(ts, payload, lines):

        pkt = dict()

        pkt['dateTime'] = ts

        pkt['usUnits'] = weewx.METRIC

        pkt.update(Packet.parse_lines(lines, AmbientF007THPacket.PARSEINFO))

        house_code = pkt.pop('house_code', 0)

        channel = pkt.pop('channel', 0)

        sensor_id = "%s:%s" % (channel, house_code)

        pkt = Packet.add_identifiers(

            pkt, sensor_id, AmbientF007THPacket.__name__)

        return pkt

    # {"time" : "2017-01-21 13:01:30", "model" : "Ambient Weather F007TH Thermo-Hygrometer", "device" : 80, "channel" : 1, "temperature_F" : 61.800, "humidity" : 10}

    # as of 06feb2020:

    # {"time" : "2020-02-05 19:33:11", "model" : "Ambientweather-F007TH", "id" : 201, "channel" : 5, "battery_ok" : 1, "temperature_F" : 39.400, "humidity" : 60, "mic" : "CRC"}

    @staticmethod

    def parse_json(obj):

        pkt = dict()

        pkt['dateTime'] = Packet.parse_time(obj.get('time'))

        pkt['usUnits'] = weewx.US

        house_code = obj.get('device', 0)

        channel = obj.get('channel')

        pkt['temperature'] = Packet.get_float(obj, 'temperature_F')

        pkt['humidity'] = Packet.get_float(obj, 'humidity')

        sensor_id = "%s:%s" % (channel, house_code)

        pkt = Packet.add_identifiers(

            pkt, sensor_id, AmbientF007THPacket.__name__)

        return pkt

My sdr.conf section for SDR:

[SDR]

    # This section is for the software-defined radio driver.

   

    # The driver to use

    driver = user.sdr

#    path = /usr/local/bin/rtl_433

#    log_unknown_sensors = False

#    log_unmapped_sensors = True

    [[sensor_map]]

        extraTemp2 = temperature.*.AmbientF007THPacket            # pool temperature

When run under weeex-multi using:

sudo /etc/init.d/weewx start sdr

I find this in the log; I think this must be the problem but I have not been able to figure out how to fix it:

import of driver failed: failed to start process 'rtl_433 -M utc -F json': [Errno 2] No such file or directory (<class 'weewx.WeeWxIOError'>)

I'm having a similar problen with a RPI3 with buster (debian 10)

i have the logs
