Problem
Absolute pressure does
not agree with official
reporting station
Rain gauge reports rain
when it is not raining
Data not reporting to
Wunderground.com
Solution
You may be viewing the relative pressure, not the
absolute pressure.
Select the absolute pressure. Make sure you
properly calibrate the sensor to an official local
weather station. Reference Section 6.6 for details.
An unstable mounting solution (sway in the
mounting pole) may result in the tipping bucket
incorrectly incrementing rainfall. Make sure you
have a stable, level mounting solution.
1. Confirm your password is correct. It is
the password you registered on
Wunderground.com. Your
Wunderground.com password cannot
begin with a non-alphanumeric character
(a limitation of Wundeground.com, not
the station). Example, $oewkrf is not a
valid password, but oewkrf$ is valid.
2. Confirm your station ID is correct. The
station ID is all caps, and the most
common issue is substituting an O for a 0
(or visa versa). Example,
KAZPHOEN11, not KAZPH0EN11
3. Make sure the date and time is correct on
the console. If incorrect, you may be
reporting old data, not real time data.
4. Make sure your time zone is set properly.
If incorrect, you may be reporting old
data, not real time data.
Check your router firewall settings. The
5.
console sends data via Port 80.
