WH3085 weewx-sdr

[Mark Fraser]

I've recently purchased a WH3085 to replace my ageing WH1080 (was a
WH3080 until the transmitter broke). In weewx-sdr I've copied the lines
referring to UV and luminosity from WH3080 over to WHx080.
IDENTIFIER = "Fineoffset-WHx080"

@staticmethod
def parse_json(obj):
pkt = dict()
pkt['dateTime'] = Packet.parse_time(obj.get('time'))
pkt['usUnits'] = weewx.METRIC
# older versions of rlt_433 user 'station_id'
if 'station_id' in obj:
pkt['station_id'] = obj.get('station_id')
# but some newer versions of rtl_433 seem to use 'id'
if 'id' in obj:
pkt['station_id'] = obj.get('id')
if 'uv_sensor_id' in obj:
pkt['station_id'] = obj.get('uv_sensor_id')
pkt['msg_type'] = Packet.get_int(obj, 'msg_type')
pkt['msg_type'] = Packet.get_int(obj, 'subtype')
pkt['temperature'] = Packet.get_float(obj, 'temperature_C')
pkt['humidity'] = Packet.get_float(obj, 'humidity')
pkt['wind_dir'] = Packet.get_float(obj, 'wind_dir_deg')
pkt['wind_speed'] = Packet.get_float(obj, 'wind_avg_km_h')
pkt['wind_gust'] = Packet.get_float(obj, 'wind_max_km_h')
pkt['uv_index'] = Packet.get_float(obj, 'uv_index')
pkt['luminosity'] = Packet.get_float(obj, 'lux')
pkt['radiation'] = Packet.get_float(obj, 'wm')
pkt['uv_status'] = 0 if obj.get('uv_status') == 'OK' else 1
rain_total = Packet.get_float(obj, 'rain_mm')
if rain_total is not None:
pkt['rain_total'] = rain_total / 10.0 # convert to cm
pkt['battery'] = 0 if obj.get('battery_ok') == 1 else 1
pkt['signal_type'] = 1 if obj.get('signal_type') == 'WWVB /
MSF' else 0
pkt['hours'] = Packet.get_int(obj, 'hours')
pkt['minutes'] = Packet.get_int(obj, 'minutes')
pkt['seconds'] = Packet.get_int(obj, 'seconds')
pkt['year'] = Packet.get_int(obj, 'year')
pkt['month'] = Packet.get_int(obj, 'month')
pkt['day'] = Packet.get_int(obj, 'day')
return FOWHx080Packet.insert_ids(pkt)

This is because both transmissions identify themselves as
Fineoffset-WHx080 except that the subtype changes from 0 to 2:

out: ['{"time" : "2022-11-01 18:23:01", "model" : "Fineoffset-WHx080",
"subtype" : 2, "uv_sensor_id" : 113, "uv_status" : "OK", "uv_index" : 0,
"lux" : 0.000, "wm" : 0.000, "mic" : "CRC"}\n', '{"time" : "2022-11-01
18:23:01", "model" : "Fineoffset-WHx080", "subtype" : 2, "uv_sensor_id"
: 113, "uv_status" : "OK", "uv_index" : 0, "lux" : 0.000, "wm" : 0.000,
"mic" : "CRC"}\n', '{"time" : "2022-11-01 18:23:04", "model" :
"Fineoffset-WHx080", "subtype" : 0, "id" : 240, "battery_ok" : 1,
"temperature_C" : 10.100, "humidity" : 74, "wind_dir_deg" : 270,
"wind_avg_km_h" : 3.672, "wind_max_km_h" : 4.896, "rain_mm" : 635.400,
"mic" : "CRC"}\n']

Could the subtype be used to switch between the 2 different types of
packet so that weewx only decodes the ones it needs?
