Remove/update archive (history) data

[Tomasz Lewicki]

Dear Weewx users.

My station was in "test mode" until midnight May 1. Now I want to remove all data before this date. SQLite database is modified and has only data after May 1, 00:00:00. But in my archive (history) data on website I see earlier months and max/min values too. How to get rid of them? I suppose some 'weectl database' command but which one?

OK, sorry for a noise. I found instructions on the wiki: https://github.com/weewx/weewx/wiki/Cleaning-up-old-'bad'-data

But it's strange that I see April's values in history section despite weewx.sdb oldest data is 2024-05-01 00:00:00.

Perhaps you're looking at an old HTML file? If you delete them all, weewx will regenerate at the next reporting cycle using the new data.
