Please make sure to enter your station ID in all capital letters. (such as "KAZTUCSO5"). The station ID is almost always comprised of eight letters and one to three numbers. If you have an "O" or "I" as the last letter before the number(s), it is very easy to mistake it as a number.
The password for your weather station is no longer the same as the password for your wunderground.com account. It is now a separate key that is generated specifically for each Weather Underground station ID. You can find the station key/password associated with each weather station in your list of weather stations here:
The password is case sensitive ("myPassword" is not the same as "mypassword"). Try re-entering the login information in your station software and upload data once more.
Note that it may take up to a few hours for observations to appear on your station's history page. Personal weather stations that return to service after being offline take at least one day to re-appear on your city/ZIP local weather forecast page.
Please "Submit a Ticket" if you continue to have trouble.
