ValueError: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md for details

Release 2.0.0 of the Paho Python MQTT includes breaking changes; this means that code written for v1.x will not work without some (minimal) modifications. As v2.0.0 was only released a few days ago (11th Feb 2024) most examples, including the one you reference, will not work.

The changes required are documented here (or here); in your case it's likely that the only change needed is add a single parameter changing:

client = mqtt_client.Client(client_id)

to:

client = mqtt_client.Client(mqtt_client.CallbackAPIVersion.VERSION1, client_id)

This will configure the library to use the v1 callback API (as used with older versions of the library). I would recommend reading the document linked above and planning to migrate to CallbackAPIVersion.API_VERSION2.

An alternative option would be to install a v1 release (v1.6.1 is the latest; pip install "paho-mqtt<2.0.0" will install this). V2 does include quite a few fixes/enhancements so it is worth considering using that version.

Die Software 2.x scheint mit meiner Hardware nicht klarzukommen (sieht EVSE und/oder Zähler nicht),

Install OpenWB on Rpi with Bullseye, step by step:

1. Write this official Bullseye image with BalenaEtcher on microSD
2. To activate ssh, Create an empty text file called ssh into the boot partition.
3. Insert the MicroSD card into Rpi and boot.
4. Login via SSH with Terminal or Putty

Code: Alles auswählen

user: pi
password: raspberry

4.1 in ssh run raspi-config

Code: Alles auswählen

sudo raspi-config

- set the hostname to openwb
- activate wait for network on boot
- extend the file system on microsd
- automatically boot on the desktop as pi user

->it needs (and ask for) a reboot

5. Run those commands via ssh, logged as pi user (not root):

Code: Alles auswählen

sudo apt update
suto apt upgrade -y -q
sudo apt-get autoremove -y
sudo apt-get autoclean -y
sudo restart

Code: Alles auswählen

sudo apt update
sudo apt upgrade -y -q
sudo apt-get autoremove -y
sudo apt-get autoclean -y
sudo reboot

wäre der funktionierende code

6. Create the script to install OpenWB (modified from the original)

Code: Alles auswählen

sudo nano /home/pi/openwb-install.sh

Paste the content of the attached openwb-install.sh.txt

openwb-install.sh.txt

Save with Ctrl+x

Hier sind etliche Fehler drinnen.
So sind viele Packages nicht erreichbar. Angefangen mit python-pip.
dafür gibt es die Lösung (gefunden auf https://www.askpython.com/python/exampl ... -candidate):
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then run it with sudo:
sudo python get-pip.py

Dann noch:
sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.0
sudo apt install php php-mysql php-curl php-json php-cgi libapache2-mod-php^C

hier hab ich jetzt mal ausgesetzt, weil es in meinen augen schon ziemlich krass viel nervkram ist. dafür bin ich auch nicht tief genug in dem thema drinnen. mit der stretch hat es ja halbwegs funktioniert, nun probiere ich noch bustian aus.


also... don´t do it xD
