openWB Embedded software replacement
Replacement for the OpenWB software, when evcc runs directly on the OpenWB hardware. Currently supported Hardware is OpenWB Series2. mA control is used automatically if the EVSE firmware supports it.
Please be aware that installing evcc on the OpenWB Hardware will void your guarantee!
Installation without display:
- Install and configure Raspberry Pi OS Lite (64bit) image.
- Add the following at then end of
/boot/firmware/config.txt:[all] gpio=4,5,7,11,17,22,23,24,25,26,27=op,dl gpio=6,8,9,10,12,13,16,21=ip,pu - Install evcc according to the manual.
- Add the groups required for user evcc to access the hardware:
usermod -a -G gpio,dialout,input evcc - Configure evcc according to the manual. There are multiple distinct Hardware versions, which differ regarding the built-in modbus
adapters and charge meters.
- A single or multiple Modbus adapters are found at
/dev/ttyUSB0,/dev/ttyUSB1(some Duo) or/dev/ttyACM0. Some Duo's contain two Modbus adapters, some just one. - The EVSE for the first connector has always the ID 1, the one for the second ID 2.
- The different possible charge meters are:
- Bernecker Engineering MPM3PM (template: mpm3pm) with ID 5 or ID 6 for the Duo's second connector.
- SDM630/SDM72 (template: eastron) with ID 105 or ID 106 for the Duo's second connector.
- ABB B23 (template: abb-ab) with ID 201
- A single or multiple Modbus adapters are found at
Additional steps for showing evcc on the display (be careful, because this will allow anybody to enable charging!). User pi is just an example here, replace it with the user actually used:
apt install labwc wayfire seatd xdg-user-dirs firefox-esr swayidle wlopm- Create the file
/home/pi/.config/labwc/autostartwith the following contents:/usr/bin/firefox-esr --kiosk http://localhost:7070/ & /usr/bin/swayidle -w timeout 600 'wlopm --off \*' resume 'wlopm --on \*' & - Create file
/home/pi/.config/systemd/user/kiosk.servicewith the following content:[Unit] Description=Start Kiosk mode [Service] Type=simple ExecStart=/usr/bin/labwc [Install] WantedBy=default.target - Enable autostart of kiosk mode:
systemctl --user enable kiosk - As root: Enable start of systemd user units without the user having to log-in:
loginctl enable-linger pi
