Last post of the day, I promise!
I think the node-red flow is working the way it should and reporting the
parsed message as in my last post.
weewx.conf configuration (changed topic to "mytopic" in the flow and in
weewx).

It seems that there is something wrong with the format coming into weewx
from the flow. It may be confused by the other two
elements "measurementId": 4100, and "type": "report_telemetry" which cause
the whole thing to fail. Is it possible to have weewx ignore these elements
and only process the "CO2_Value_PPM": 419 ? I'm not sure what "float" does
but mayve that's a problem...?
Thanks again and I'll have another look tomorrow.
Cheers,
Bob
