WLK importer

This extension imports WLK files into WeeWX by emulating a driver. This has the advantage of subjecting the imported data to the same processing pipeline as real data, including any extensions.

Prerequisites

• Python 3.7+
• WeeWX V4.6+

Installing the extension

Copy your configuration file

This extension requires modifying your weewx.conf file. Rather tha modify your only copy of the file, it's safer to make a copy, then use that. For example:

cd ~/weewx-data
cp weewx.conf weewx-import.conf 

Run the installer

The extension is installed like any other WeeWX extension, except that you should use the config file created above:

weectl extension --config=~/weewx-data/weewx-import.conf install https://github.com/tkeffer/weewx-wlk/archive/refs/heads/master.zip 

Configure the extension

1. Stop weewxd.

2. Edit the copy of weewx.conf to set the driver to the WLK importer. Under the [Station] stanza, change the line station_type so it reads:

   station_type = WLK
   

3. In the [WLK] stanza, set option wlk_files to the pathway to the WLK file(s) that you intend to import. Wildcards can be used. The tilde symbol (~) can also be used. For example:

   [WLK]
       wlk_files = ~/Downloads/2018-??.wlk
   

   In this example, all WLK files with 2018 dates would be imported. Substitute as necessary.

4. Run weewxd directly from the command line, using the config file that you created. Typically, this looks like:

   weewxd --config=~/weewx-data/weewx-import.conf
   

   Monitor the output to make sure that the import is successful. When the import is complete, it will end with a not-implemented error that looks like this:

   NotImplementedError: WLK import complete. Ignore this exception.
   

   This is the normal end of the import process.

5. Restart weewxd.
