V3.60~39 dbus mqtt devices not working - Scarthgap packages unavailable

Beta testing Venus OS beta testing

Great, we’re one step further. So for now, I did the following:

Change package repository to “Candidate”:

/opt/victronenergy/swupdate-scripts/set-feed.sh candidate

The Python tomllib needs to be added manually:

opkg install python3-tomllib

Installation of dbus-mqtt-devices:

Now, the installation is working fine but I’m running into the Paho MQTT version incompatibility:

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

As dbus-mqtt-devices is referring to the /opt/victronenergy/dbus-mqtt library, I’m not sure how and where to change the CallbackAPIVersion attribute so we’re not there yet. I think this is where the driver needs to be updated @freakent
