hello Sathish, I would suggest you read the weewx manual first (link at the bottom). All the questions you've asked are explained there in an easy-to-follow manner. Including the required skills anybody wanting to use weewx needs to have, quote:
You should have the following skills: - The patience to read and follow this guide; - Willingness and ability to edit a configuration file; - Some familiarity with Linux or other Unix derivatives; - Ability to do simple Unix tasks such as changing file permissions and running commands; - No programming experience is necessary unless you wish to extend weewx. In this case, you should have some familiarity with Python http://weewx.com/docs/usersguide.htm -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
