ID values for sensor_map for rtl_sdr

[Richard Horobin]

I'm confused by the ids for my Acurite 5n1 and AmbientWeather WH31E sensors. SDR.PY has found the ID of both devices. For the Acurite, it generated the hex value of ID, but for the Ambient, it didn't.

Question: should I continue with the decimal value of ID for the Ambient device?

I did:

PYTHONPATH=. python3 user/sdr.py --cmd="rtl_433 -C si -M time:utc -F json -G 4" --debug

Sensor: Acurite 5n1

out: ID = 1030

parsed: ID = 0406

Sensor: AmbientWeather WH31E

out: ID = 148

parsed: ID = 148

Here are the corresponding rows of output:

I believe the ID for your Acurite will be 0406, you will use an entry like this in your sensor map: 

windSpeed =  wind_speed.0406.Acurite5n1PacketV2

...and your WH31E will be 148, so again the sensor map entry will be:

inHumidity = humidity.148.AmbientWH31EPacket
