Hi,
this might be interesting to some of you. I wrote a simple service which polls data from the OpenEVSE (EV Charger, mqtt/json) and puts the data on dbus.
asked
EV Charger integration: OpenEVSE
Super!!! Am waiting for OpenEvse charger so I will try that service.
Thank you!
Very cool!!
I'm just 2 open evse working in my network and also a complete Victron PV system ( with Cerbo GX, batteris etc etc...
I'm inexperienced in Cerbo GX software ; how i can install this software ( i need root access?.. ssh access ?).
Ciao,
Fabrizio.
Yes, need root access and ssh active.

Putty ssh, install dbus-evsecharger:
wget https://github.com/JuWorkshop/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
Thanks of you i was able to install the script and work great!!
The only wrong info is the EVSE in shown in critical load side, but in real it is connected to ACin1 side.
Fantastic script !!
You can change the position by adding this around line 58 of dbus-evsecharger.py
self._dbusservice.add_path('/Position', 0) # normaly only needed for pvinverter
Tanks for your support.
If i append this line at the end of object definition ( as shown ) , my PV inverter ( in ACin ) stop to work and also the Open EVSE do not work.
self._dbusservice.add_path('/ProductId', 0xFFFF) #
self._dbusservice.add_path('/ProductName', productname)
self._dbusservice.add_path('/CustomName', productname)
self._dbusservice.add_path('/FirmwareVersion', int(data['divert_update']))
self._dbusservice.add_path('/HardwareVersion', 2)
self._dbusservice.add_path('/Serial', data['comm_success'])
self._dbusservice.add_path('/Connected', 1)
self._dbusservice.add_path('/UpdateIndex', 0)
self._dbusservice.add_path('/DeviceInstance', deviceinstance)
self._dbusservice.add_path('/Position', 0) # normaly only needed for pvinverter
Hmm, maybe this just works for Inverters then. I assumed it would work here too. There's are what the values ordinarily equate to.
- 0 = input
- 1 = output 1
- 2 = output 2
I've installed this on my system and can see the data - thanks. The only thing that I can change via the settings is the "Enable Charging". when I try to change the "Charging Current" it doesn't let me change it. Also, the "Position" is shown as "Unknown". If I Change this to "AC Output" and then levee the menu, when I come back it shows "Unknown" again.
Have I messed up the installation somehow?
Thanks
I fork it and made some changes in order to work with new openevse firmware
https://github.com/ayasystems/dbus-evsecharger/
Please check it, it works with ESP32 and firmware 4.1.x
