question

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.
Cerbo : https://youtu.be/L9BHSJEpTD8?t=158

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 !!

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

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

On Fcattaneo's screen shot for the EVSE it says "waiting for sun". Is it possible to setup rules for when to use the EVSE based on SoC or a minimum current from the PV array??

I do not have an OpenEVSE charger but an OpenWB wallbox.

It's easy to read the needed data using mqtt (only a few lines of code) - but I'm not an Python expert to merge these lines into your code.

This is the code to read from OpenWB:

import paho.mqtt.client as mqtt

def on_connect(client, userdata, flags, rc):
        if rc == 0:
            print("Connected to MQTT Broker!")
        else:
            print("Failed to connect, return code %d\n", rc)

def on_message(client, userdata, msg):
        if "openWB/lp/1/VPhase1" in (msg.topic):
             temp = float(msg.payload)
             print("L1 Power: ", temp)
        if "openWB/lp/1/VPhase2" in (msg.topic):
             temp = float(msg.payload)
             print("L2 Power: ", temp)
        if "openWB/lp/1/VPhase3" in (msg.topic):
             temp = float(msg.payload)
             print("L3 Power: ", temp)
        if "openWB/lp/1/kWhCounter" in (msg.topic):
             temp = float(msg.payload)
             print("Energy consumed by charger: ", temp)
        if "openWB/global/WAllChargePoints oder openWB/lp/1/W" in (msg.topic):
             temp = float(msg.payload)
             print("Total Power: ", temp)
        if "openWB/config/get/sofort/lp/1/current" in (msg.topic):
             temp = float(msg.payload)
             print("Charge Current: ", temp)
        if "openWB/lp/1/boolPlugStat" in (msg.topic):
             temp = float(msg.payload)
             print("Plugin Status: ", temp)
        if "openWB/lp/1/boolChargeStat" in (msg.topic):
             temp = float(msg.payload)
             print("Ladestatus: ", temp)

client = mqtt.Client()
client.on_message = on_message
client.on_connect = on_connect
client.connect("192.168.178.20", 1883)
client.subscribe("openWB/#")
client.loop_forever()

It would be great to get some help to adopt this script to work with an OpenWB.

@adahmen Where I can find openwb source code?

@ju@workshop Ju, what do you suggest to do before upgrade the Cerbo GX firmware ( when your application are installed ) ?

Thanks,

Fabrizio

Hello

And congrats, for the work, well done.

It's possible to no on VRM the statistics of charger sessions, to add?

Or depends from Victron..

Tks nice job

Hi All,
Im trying to use this code (actually the https://github.com/ayasystems/dbus-evsecharger version as I have wifi v5.02) and having some problems with it not working. Wondering how I can find the log files to troubleshoot.
Many thanks!

Mike.
