How did you delete the readings? Did you use a tool like DB Browser for sqlite? If so, when it deletes a value, unless you tell it otherwise, it inserts an empty string, instead of a "null" value, which will cause your problem.
The tool wee_database <http://weewx.com/docs/utilities.htm#wee_database_utility> can fix this. First run with the --check-strings <http://weewx.com/docs/utilities.htm#wee_database_utility_check_strings> option, then the --fix-strings <http://weewx.com/docs/utilities.htm#Action_--fix-strings> option. -tk On Mon, Nov 5, 2018 at 2:24 AM Richard Cain <richardtc...@gmail.com> wrote: > Hi > I recently had my usual problem with inaccurate rain readings so I had to > stop weewx, delete the wrong readings and restart.
