Practical steps to upgrade from Weconnect-mqtt to CarConnectivity-mqtt?

[Domoberry]

Hi All,
I understand that as a (happy) user of Weconnect-mqtt, I need to upgrade to CarConnectivity-mqtt. I would appreciate some suggestions, experience, steps, etc. which I can use to perform this upgrade. Not being an expert, with the risk of asking something obvious, I would rather be safe than sorry :-)
On the current setup: I'm currently using a RPI4b running Pi OS Bullseye. Weconnect-mqtt was installed using pip3 (currently weconnect-mqtt 0.49.2 (using WeConnect-python 0.60.8)). NodeRed is used to 'convert' some VW ID3 WeConnect mqtt messages of interest to MQTT messages my home automation system (Domoticz) can easily digest. I'm not using Auto Discovery.
Thanks in advance!

If you already know Weconnect-mqtt it should be easy to change. Biggest change is probably that the arguments are passed in a config file instead of with parameters. Also the topics changed a bit, but when you look for the topics carconnectivity/testing/plugins/mqtt/topics and carconnectivity/testing/plugins/mqtt/writeable_topics you should find out the new topic names pretty easy.

Hi Domoberry,

I read that you use this plugin together with Domoticz. I do also! I can recommend you the small Domoticz hardware plugin 'MQTT Mapper' (https://github.com/FlyingDomotic/domoticz-mqttmapper-plugin ) where you can convert / digest MQTT messages for Domoticz very easy. And saves you the installation of NodeRed.
