If you stop weewx, then delete the sqlite file, then you will start with a brand new database.
If you just want to delete rows, open the sqlite file on command line (sqlite3 weewx.sdb) or in a tool like DB Browser for SQLite <https://sqlitebrowser.org/> and find the dateTime you want to delete. Then run this SQLite command. Change 123456 with the correct dateTime delete from archive where dateTime = "123456" Disclaimer: have a backup of your database in case you want to undo what you did. You are responsible for any changes you make. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
