Weather station CT1EIF-11 not appearing on aprs.fi

[Rui Ferreira (CT1EIF)]

Hello all,

I am the operator CT1EIF and have configured my weather station (PWS IMOURA16) to send data via APRS-IS. From my side, the system is fully functional and the packets are accepted by the server, but the station does not appear on the aprs.fi map.

Example lines from my local log:

Starting continuous upload of weather data to aprs.fi... Packet generated: !3807.68N/0727.15W_/t034h25r000s007d108 Login response: # aprsc 2.1.19-g730c5c0 Packet accepted by APRS-IS: !3807.68N/0727.15W_/t034h25r000s007d108

Configuration details:

• Callsign: CT1EIF-11

• Location: 38.1281N / 7.4525W (Moura, Beja, Portugal)

• Port: 14580 (APRS-IS)

• Passcode: verified successfully

I would like to confirm if there are any limitations, delays, or additional requirements for my weather station to appear correctly with the WX icon on aprs.fi.

Thank you very much for your support.

Best regards,

Rui
CT1EIF

Hi,

There are some problems with the packets you're sending, the errors will
be reported in the aprs.fi raw packets display:

https://aprs.fi/?c=raw&call=CT1EIF-11&limit=50&view=normal

- There are apparently two different stations sending position and weather
packets with different coordinates. Weather stations are not supposed to
be moving or jumping around. If you have two weather stations, they need
to use different SSIDs.

- Previously one station had coordinates incorrectly formatted, but that
seems to have been fixed.

Additionally, if you look at the decoded packets, only one of the station
gets the weather encoded correctly. The other one is not sending a
correctly formatted weather packet and aprs.fi is not decoding it. It's
probably the capital 'G' instead of 'g' for wind gust.

Here the data is correct

I changed SSID to -13 to do new test

Hello, Heikki Hannikainen

Thanks for your answer, but it is not easy for the station to send packages to APRS.fi, I am using a 7 -in -1 metereological station VEVOR  YT60234 connected to weather underground and an Raspberry Pi5 that collects the data and sends them (should send) to APRS. This is the script I'm using, I've made hundreds of changes but I haven't got it right yet, at the beginning still sent packages but the data were wrong, the current temperature in my city is 33ºC and APRS.fi appeared -2.2ºC

 Thanks

Hello,

Apparently you have a problem with the python script you're trying to use
to upload data to APRS-IS.

This is off-topic for this group, as the problem is not for aprs.fi
itself, but rather an APRS-IS client. Please look for a forum supporting
the weather software, or the source of the script you're using.

aprs.fi reports decoding problems in the raw packets view quite well,
that feature can be used to diagnose encoding problems.

73!

Hi,

CT1EIF-13 is sending regular packets (as just reviewed them on aprs.fi raw packets

on your python script you are not uploading the Temperature as Fahrenheit  (Celsius should be transformed to upload it)
