I cannot see RAIN RATE in the settings ....
I have a Davis Vantage pro2 and Davis Vantage Vue weather station with data logger.
I report to weather underground which is now getting worse by the day and to PWS.
Make the site as sexy as possible without too much clutter.
Yes I will be willing to offer your station data to anyone else (not only windy.com) as open data.
