Python plugin: Wallbox EV charger

[Lokonli]

I've created a plugin for integration of the Wallbox EV charger into Domoticz.

The plugin uses the Wallbox API.

Cewl.
Happy with this charger ??
I'm looking at the 'Copper SB' as the others seem to have wifi range issues.

Thanks, great plugin .

Just installed it without too much problems, and seems to work great!
Minor comment which I just noticed, The device "Charging current" should be power in kW instead of current in Ampere; at least the metric corresponds to that in the Wallbox app.

Works like a charm with Walbox Copper.

Anyone successful with integrating Walbox with OCCP 1.6 in Node-Red for example?

Updated the plugin a bit:

Found this trick.
https://github.com/jagheterfredrik/wallbox-pwn

together with:
https://github.com/jagheterfredrik/wallbox-mqtt-bridge

It allows you to obtain full control and all data locally from the Wallbox without breaking the Cloud functionality.
It publishes data to MQTT every second.

We could add this to a separate plugin or use something like a ShellyTeacher4Domo kinda approach to automatically create these devices in Domoticz.

Or use the mqttmapper plugin. I think this would be the easiest way.

Again, your knowledge (walking wiki) always seems to amaze me. Thanks for the tip!!

Hello,

Interesting topic. I've looked at the two versions of the plugin mentioned in this topic:

https://github.com/lokonli/domoticz-wallbox
https://github.com/sincze/domoticz-wallbox

Which one should I use? I've just tried installing them both (to folders wallbox and wallbox1) and I can't see work out what the differences are!
Thanks

Hi tarmacalastair
https://github.com/lokonli/domoticz-wallbox is leading.
I forked it (to create pull requests for improvements) and if agreed upon lokonli merges them in his release.

Ah great, thanks for explaining.

I started using this plugin earlier this week.
Was very excited at first but over first days it broke on me and I cannot find the reason for it.
The domoticz log says:

2024-06-21 20:27:52.257 Error: wallbox: (Wallbox) failed to load 'plugin.py', Python Path used was '/opt/domoticz/userdata/plugins/wallbox/:/usr/lib/python39.zip:/usr/lib/python3.9:/usr/lib/python3.9/lib-dynload:/usr/local/lib/python3.9/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.9/dist-packages'.

2024-06-21 20:27:52.269 Error: wallbox: ModuleNotFoundError: No module named 'wallbox'

I cannot find any errors in the plugin.py file from the original. Any suggestions?

Running domoticz 2024.4 in docker.

[sincze]

It seems docker does not know wallbox.
Probably the docker was renewed??

How did you install the plugin in the docker?

[edwinh81]

I cannot really reproduce how I did it.
I adapted the installation like described on github a little.

I kicked the pip install line again with a commandline and it works again for now.

Do you have any advice on what would be a proper way to do it in docker?

[sincze]

I created a customstart.sh. So everytime my Domoticz container is re-created the wallbox is re-installed.
https://www.domoticz.com/wiki/Docker#cu ... _container

The plugin itself is maintained as this is mounted into the docker.

Code: Select all

#!/bin/bash

if [ -f /opt/domoticz/FIRSTRUN ]; then true
else
echo 'Installing Wallbox'
pip install -r /opt/domoticz/userdata/plugins/wallbox/requirements.txt
echo 'Creating FIRSTRUN file so script can check on next run'
touch /opt/domoticz/FIRSTRUN
cd /opt/domoticz || return
fi

Thank you!
Far as I can see now this did the trick for me.
