I wrote a larger post which was instantly deleted by the group which I
don't feel like typing all out again.
Debian / weewx 3.9.1 with mqtt extension / belchertown / nginx / david
vantage pro2
Here is the issue in short:
MQTT appears to be working internally but the payload is rather large and
prevents the website from updating. A smaller fake payload used for
testing is successful. How do I truncate the data in the MQTT payload?
things like soil and leaf wetness are not required.

The site just shows "Connected. Waiting for data."

Using MQTT-admin I can see payload size errors:

Sending a smaller fake payload from the terminal successfully updates the
website:
