This is a simple python script that collects data from dbus on your Victron CCGX or Venus-GX, and posts it to pvoutput.org. This is mostly a proof of concept designed to work on my particular single-phase setup. Extending for other systems is left as an exercise to the user.
- Assumes single phase system
- Assumes no PV inverters
- Assumes there is a grid meter
- Should also work for off-grid systems without a grid meter.
- On pvoutput, battery charge and discharge shows up as export and import.
- It uses the timezone information from the CCGX settings, not the system timezone.
- You have to add your APIKEY and SYSTEMID in the config.ini
- If you want to enable weather information, register on openweathermap.org then add apikey and cityid in config.ini
- Use dbus-pvoutput.py prior Venus 2.80
- Use dbus-pvoutput-p3.py VenusOS 2.80 and later
- Copy the 2 files, config.ini and dbus-pvoutput.py or dbus-pvoutput-p3.py depending on your VenusOS to you GX Device, with scp.
- Make sure you modify the config.ini with your correct settings.
- Login to your GX Device and then you run the script: python bus-pvoutput-p3.py
- To be able to run the script and logout out you can use this: "nohup python dbus-pvoutput-p3.py &" NOTE: if GX reboots you need to run the script again or you need to add the script so that it runs on reboot as well.
- FIX permissions of script : chmod ug+x /data/home/root/dbus-pvoutput/dbus-pvoutput-p3.py
- Config.ini NEEDS to have proper permissions to avoid errors. i had to chmod 777 in order to stop the nosection found error....
- Add to /data/rc.local so it runs on every boot this : su root -c "screen -dm -S pvoutput python /data/home/root/dbus-pvoutput/dbus-pvoutput-p3.py"
