Direwolf 1.5 adding PHG5100327 to wx pckets

[jondkelley]

Issue noticed in Direwolf 1.5

I have a script that generates wxnow

# curl -s http://192.168.1.250:5000/wxnow.txt | tail -1
325/000g000t067r000p000P000h077b10118N5IPT Hi from Westwood in Kalamazoo, MI!*digi-gate*Direwolf on Rasp.Pi 1[2011]***see my weather station open source Python code @ https://github.com/jondkelley/eco_aprs_weather {ECOWITT}

I also have a beacon setup

PBEACON sendto=0 delay=0:30 every=17:17 power=30 height=25 gain=11 lat=42.303690 long=-85.628359 SYMBOL="weather station" COMMENTCMD="curl -s http://192.168.1.250:5000/wxnow.txt | tail -1"

For some reason my packets are showing up with a weird string PHG5100327

I think this string makes weather packet decode impossible on aprs websites.

Any idea what causes this?

[jondkelley]

I now suspect it is

power=30 height=25 gain=11

Please note that Direwolf v1.5 is very old. Please rebuild using the "dev" branch here in Github as it's effectively the upcoming 1.7 version which has a lot of bug fixes, improvements, etc.

Weather report with position can't have PHG. Here is an easy way to see if a packet is valid, and what it means.

echo 'aprspacket' | decode_aprs

example:

echo 'WESTWD>APDW15:!4218.22N/08537.70W_PHG5100325/000g000t067r000p000P000h077b10120N5IPT Hi from Westwood in Kalamazoo, MI!digi-gateDirewolf on Rasp.Pi 1[2011]***see my weather station open source Python code @ https://github.com/jondkelley/eco_aprs_weather {ECOWITT}' | decode_aprs

That was not recognized as a valid weather report. Now remove the PHG5100..

The weather was MOSTLY decoded properly.

Why was "7b10120" considered leftover? If we look at the WXNOW.TXT format https://cumuluswiki.org/a/Wxnow.txt "h" should be followed by only two digits. You have three and the barometric pressure was not decoded.

If we remove the extra '0', after the 'h', we get:

Humidity is now decoded properly.

This is now correct. you need to have only two digits for humidity.

Here's your problem:

fields.append("h%03d" % (int(humidity_outdoor)))

Humidity is TWO digits.
