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/tm-107/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/uninstall.sh /data/dbus-evcc/restart.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 value	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
DEFAULT	LoadpointInstance	Read readme.md first! Default = 0. Count up for every additional loadpoint
DEFAULT	AcPosition	Charger AC-Position: 0 = AC out, 1 = AC in
ONPREMISE	Host	IP or hostname of EVCC

If you have two or more load points in EVCC

1. Follow the installation instructions above, but change the commands as follows:

   wget https://github.com/tm-107/dbus-evcc/archive/refs/heads/main.zip
   unzip main.zip "dbus-evcc-main/*" -d /data
   mv /data/dbus-evcc-main /data/dbus-evcc-1
   chmod a+x /data/dbus-evcc-1/install.sh
   /data/dbus-evcc-1/install.sh
   rm main.zip
   

   (Count up dbus-evcc-1 for each loadpoint)
2. Update the dbus-evcc-1/config.ini:
   • The deviceinstance should be different for each loadpoint: Use 43 for the first. Use 44 for the second loadpoint...
   • Change LoadpointInstance according to your evcc-configuration

If you have more than two loadpoints, the procedure is the same, but the index should be counted up.
