I'm currently running Weewx 4.9.1 and using WeeWX-MQTTSubscribe to capture
data from 2 separate RTL SDR's. One of the RTL-SDR devices is listening on
433.92 and is picking up weather data from a couple nearby weather
stations. One of the weather stations I'm listening to has a bad wind
sensor, so I do not want the wind data from that station, the other station
has good wind data so I do want that data. These two stations are from the
same manufacturer and fall under the same device decoding protocol ( [40]
Acurite 592TXR Temp/Humidity, 5n1 Weather Station, 6045 Lightning, 899
Rain, 3N1, Atlas).
The other RTL-SDR is listening on 915.00 in order to pick up pressure data
from another sensor.
When using
`rtl_433 -F json -M utc -R 40 | mosquitto_pub -t weather/radio -h localhost
-l`
I receive all packets from both stations and pass that to the
WeeWX-MQTTSubscribe driver where I have set up the various fields and map
them to weewx. For example, the wind data:
[[topics]]
unit_system = US
[[[weather/radio]]]
... snip ...
[[[[*wind_avg_km_h*]]]]
name = windSpeed
[[[[*wind_dir_deg*]]]]
name = windDir
... snip ...
since both stations emit, for example, 'wind_avg_km_h', I don't have a way
to filter out one of them (the bad one) so I end up getting some garbage
data in the mix with good data.
My question is this: since these two stations are the same 'device decoding
protocol' (40) is there a way to differentiate between the json data coming
from the one vs the other? The both have different [[[[id]]]] fields, the
one I want has an ID of 3522 and the one I don't want wind data from is ID
2849.
Essentially I want to keep data from both devices but exclude just the wind
data from one of them.
Thanks much for any help you all can provide.
