Vince is right that you need V4.5. But, your command is also wrong. Review the docs for wee_database <http://www.weewx.com/docs/utilities.htm#wee_database_utility>.
The --config option selects a *configuration file*, such as weewx.conf, not a database. The --binding option selects the *binding*. By default, it uses the binding wx_binding. So, if you want to use a second database, such as envoy.sdb, it must first be listed as a binding. For example, [DataBindings] [[envoy_binding]] # The database must match one of the sections in [Databases]. # This is likely to be the only option you would want to change. database = envoy_sqlite # The name of the table within the database table_name = archive # The manager handles aggregation of data for historical summaries manager = weewx.wxmanager.WXDaySummaryManager # The schema defines the structure of the database. # It is *only* used when the database is created. schema = schemas.wview_extended.schema [Databases] # A SQLite database is simply a single file [[envoy_sqlite]] database_name = envoy.sdb database_type = SQLite This sets up a new binding envoy_binding, which uses envoy.sdb. Now you can add a new column to the new binding: *wee_database --add-column=mynewcolumn --binding=envoy_binding* On Mon, Apr 19, 2021 at 12:57 PM vince <vinceska...@gmail.com> wrote: > Your weewx is too old.
