dbus-open-evcc

Integrate EVCC charger into Victron Venus OS

Purpose

This script supports reading EV charger values from EVCC. Writing values is not supported right now

Install & Configuration

Get the code

Just grab a copy of the main branche and copy them to a folder under /data/ e.g. /data/dbus-evcc. After that call the install.sh script.

The following script should do everything for you:

wget https://github.com/SamuelBrucksch/dbus-evcc/archive/refs/heads/main.zip
unzip main.zip "dbus-evcc-main/*" -d /data
mv /data/dbus-evcc-main /data/dbus-evcc
chmod a+x /data/dbus-evcc/install.sh
/data/dbus-evcc/install.sh
rm main.zip

⚠️ Check configuration after that - because service is already installed and running and with wrong connection data (host) you will spam the log-file

Change config.ini

Within the project there is a file /data/dbus-evcc/config.ini - just change the values - most important is the deviceinstance under "DEFAULT" and host in section "ONPREMISE". More details below:

Section	Config vlaue	Explanation
DEFAULT	AccessType	Fixed value 'OnPremise'
DEFAULT	SignOfLifeLog	Time in minutes how often a status is added to the log-file current.log with log-level INFO
DEFAULT	Deviceinstance	Unique ID identifying the charger in Venus OS
ONPREMISE	Host	IP or hostname of EVCC
