This is an extension to weewx that emits data to a file in the format used by Cumulus wxnow.txt. The format for the wxnow.txt file is maintained at the Cumulus web site:

http://wiki.sandaysoft.com/a/Wxnow.txt

wget -O weewx-cwxn.zip https://github.com/matthewwall/weewx-cwxn/archive/master.zip

1. Run the extension installer:

weectl extension install weewx-cwxn.zip

2. Modify weewx.conf:

    [CumulusWXNow]
        filename = /var/tmp/wxnow.txt

3. Restart weewx

sudo systemctl stop weewx
sudo systemctl start weewx

The wxnow.txt file should be modified on each LOOP. For some stations the update will happen more often than others. For example, Vantage sensors update as often as every 2.5 seconds, whereas FineOffset stations never update more often than 48 seconds.
