Is your reported cloud base a calculated value, or do you have a fancy
LIDAR or something to get that info?
And same for percentage of cloud cover, 19% seems very precise. Is that
just picked off the range of cloud cover or is there some way you can
measure that value?

What is the right unit for longitude and latitude?
They should be degrees, but other then for temperature or compass I
couldn't find any other ...

This is an awesome group!
Without your help of so many folks, I would not have achieved what
I have so far ...
Still need to do more to pass the coordinates to Belchertown skin
forecasts and weather warnings ...
But I am getting there now (I hope) ...
Thank you all again for your help!

She did a lot of work to use German weather data (DWD) with
the Belchertown skin.

Vince, thank you again for the scripts ... once I figured
out that my MQTT requires user & password, it works now ...
seems that I still have to do something with the units for
the GPS coordinates ...

Yes. ipv6 is an adventure. I tried to turn it on for
my home LAN and DNS was a big problem until I figured
out that I just needed to always use "hostname.local"
for the LAN DNS and it would work. Unfortunately it
also seemed to break my pihole ad-blocking so I turned
ipv6 back off here after a few day test.
I like the clock on your About page too!

Dear Vince,
thank you very much for providing the scripts! I
really do appreciate!
However, last Tuesday I changed my ISP. Good think
- it is 1 Gbps! And my challenge was that it is
IPv6 and I had to learn very quickly that port
forwarding with IPv6 is completely different to
IPv4, and even more particular DDNS with IPv6.
But I am happy to report that my server is back
online rv.sgplex.de <http://rv.sgplex.de> :)
As I will be on vacation in Spain the next few
weeks, I will place your scripts in action!
Thanks again for providing them!
Cheers

(sorry - ignore the earlier truncated post)
I cooked up a bash script that subscribes,
calls a python script to reformat, then
publishes. The bash script sleeps a second
between loops to not eat up your cpu. You
'should' be able to change the variables in
the bash script to match your configuration
pretty easily...
This subscribes to ORIGINAL_TOPIC and
publishes to FINAL_TOPIC in the bash script.
To test:
* open a bash window and subscribe to the
FINAL_TOPIC
* open a second window and run the bash
script which will listen/reformat/publish
* if you're not querying your gps currently,
open a third window and publish to the
ORIGINAL_TOPIC ala
mosquitto_pub -h 192.168.1.171 -t RV/original
-m
'[{"dateTime":"1693128700.0","gpsLat":"52.152435"},{"dateTime":"1693128700.0","gpsLong":"9.929356"}]'
What you should see in window1 that is
subscribing is output ala:
{"dateTime": "1693128700.0", "gpsLat":
"52.152435", "gpsLong": "9.929356"}
That kind of data should be ok to subscribe to
in weewx for your lat/lon data....
#---- reformat_mqtt.bash ----
#!/bin/bash
#
# ip address of MQTT broker

while true; do
# subscribe to a topic
# run the python script to reformat to stdout
# publish to a final topic
mosquitto_sub -C 1 -h ${BROKER} -t

done

I asked in the community forum for my
router and I was told that this is the
only way they can currently forward data
via MQTT.
A future firmware release shall allow more
formatting.
I might now play around with this
https://github.com/mrtncls/mqtt-translator
to get the MQTT payload from an array in
one single statement ...
Anybody used the MQTT Translator for this
purpose?

This is what I specified in the

We'd have to see your code to see
what you are publishing.
Your MQTT log looks very odd and
likely needs some tweaking
MQTT:
[{"dateTime":"1693128700.0","gpsLat":"52.152435"},{"dateTime":"1693128700.0","gpsLong":"9.929356"}]
I'd expect something like
{"dateTime":"1233456",
"gpsLat":"52.1234", "gpsLong":
"9.987"} for a more typical set of
JSON to publish. You want one
element (not in an array) with
three items therein -
dateTime/lat/lon.
