Register your station on Weather Underground to obtain a station ID and station key/ password:
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:
Then you can enter this station ID and station key/password in your RainwiseNet settings page in the Weather Underground section (under Partner Services)
