connection error #249

I have logged in with this command
weconnect-mqtt --username [email protected] --password mysecretpas --mqttbroker 192.168.0.156 --prefix weconnect&

in MQTT there are first 6 or 7 messages at startup. One of them is weconnectconnected with payload true

Then at an interval of 5 minutes 2 error messages arrive
error/code with payload -6
error/message with payload "Retrieval error during update. Will try again after configured interval of 300s"

When retrieving the journalctl it looks like weConnect-mqtt stopped ?

pi@theone:~ $ journalctl -u weconnect-mqtt

I also tried to send a write message without result. And also no trace (that I know of) that is has been send to the server.

I also had the program running from systemd.
There it is active, but with the same error code and message in MQTT

Any ideas ?

is it always the case that no data is coming? Can you check with WeConnect-cli if data is coming?

yes, ping is working

I was running on python 3.7. I have upgrade to 3.11. But still the same issues

Can it maybe have to do something with my country setting ? When goint go www.myvolkswagen.net I need to select my country (BE-nl). But then everybody form outside Germany should have this problem...

Python 3.7 is a problem and your log indicates that you are still running on python 3.7, can you check that?

dwindey1 Sep 4, 2023

the strage thing is it should run on 3.11

pi@theone:~ $ python --version
Python 3.11.4

but some parts (or all) seem to run on 3.11

sorry, I mean some part (or all) seem to run on 3.7

Thanks fo looking into it.
And a special thanks for making this software !

I fixed the python issues.
weconnect-cli is throwing new issues, but similar to the first issues

ping heise.de works fine, so probably not a network problem

I reinstalled requests and urllib3 but with no succes.
When reinstalling urllib3 a waring came that requests for weconnect needed to be version 2.28.1. So I intalled that version.

What does WeConnect-cli —version give?

dwindey1 Sep 6, 2023

Indeed it was an older version...
It is working like a charm now !
The data coming out of the vehicle is amazing !
Thanks for the support .

You are welcome! I now understand what happened. When you had python 3.7 pip downloaded the last version that was available with 3.7 support. But that version is not working anymore with the VW servers.

I was sure I had done an upgrade when installing, so was surprised the version was not good.Good you have the insight in version management.MQTT control messages don't work with my car. But they do work with weconnect-cli. So not realy a problem.As a little positive feedback for what I am using your applications for. We have a solar and wind powered house. With the coming of an electric car and a heat pump energy management is very important. I build an home automation system in Node Red. Most electricity intense appliances are monitored and controlled so we can use as much electricity we produce ourselves.With weconnect-mqtt/cli the charging power for tje car can be changed or pauzed. So I don't need to install an expensive dynamic charging station.With a smart household we can make the world a bit better.Verzonden vanaf mijn Galaxy -------- Oorspronkelijk bericht --------Van: Till Steinbach ***@***.***> Datum: 6/09/2023 22:48 (GMT+01:00) Aan: tillsteinbach/WeConnect-mqtt ***@***.***> Cc: dwindey1 ***@***.***>, Author ***@***.***> Onderwerp: Re: [tillsteinbach/WeConnect-mqtt] connection error (Discussion #249) You are welcome!

Nice! Regarding control with MQTT, do you use the topics ending on _writetopic?
