dbus-open-evse

Integrate Open_EVSE charger into Victron Energies Venus OS. Original code could be found here -> https://github.com/JuWorkshop/dbus-evsecharger This modification allow use with new version of Openevse firmare (ESP32 4.1.x)

Minimal firmware to use this driver should be 4.1.x

Purpose

This script supports reading EV charger values from openEVSE base charger. Writing values is supported for "Enable charging"and "Charging current"

Install & Configuration

Get the code

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

The following script should do everything for you:

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

⚠️ Check configuration after that - because service is already installed an 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-evsecharger/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 EvCharger
DEFAULT	position	0 OUT / 1 IN
ONPREMISE	Host	IP or hostname of on-premise OpenEVSE (note use user password if it is needed
