Rainrate error #31

Closed Russell797 closed 10 months ago

Russell797 commented 10 months ago

Using 0.6.3 rainrate produces output some 25 times the correct value in inches.

"rfall":"1.85","rrate":"18.00","rrateTM":"180.6", when the rate was 0.71 in/hr rainfall is correct Rainrate gauge reads 18.00 in/hr

Going to need a bit more information to track down the issue, the 25 factor suggests that somewhere a value in inches is being read as mm or vice versa. Can you please post some output:

  1. A copy of gauge-data.txt generated by the extension, doesn't need to be showing erroneous rain data but needs to be complete.
  2. A copy of a loop packet from your station, preferably close in time to the gauge-data.txt above. You can capture this from the console by running WeeWX directly.
  3. A copy of the [RealtimeGaugeData]' stanza fromweewx.conf`. The information should be benign but just check and obfuscate any sensitive info like API keys etc.

Thank you. I believe I have found and fixed the issue. Could you please:

  1. locate your existing rtgd.py (it may be in /home/weewx/bin/user or /usr/share/weewx/user depending on your WeeWX install type)
  2. download the updated rtgd.py using: 
    wget -P /var/tmp https://raw.githubusercontent.com/gjr80/weewx-realtime_gauge-data/master/bin/user/rtgd.py
  3. replace rtgd.py identified at 1. with the rtgd.py in /var/tmp downloaded at 2.
  4. restart WeeWX

Unfortunately you will need to wait until some more rain falls before being able to see it the issue if fixed. Please let me know the outcome.

Russell797 commented 10 months ago

Ok, it is raining and everything is working fine. Issue resolved.
