Looking for collaborators for Victron -> Grafana project

Hello! I am currently playing around with an off grid system for collecting victron data to display on grafana (with no internet). The system uses an influxdb server. At the moment it kind of works, but it is very hacky. It collects data via a cron job to query the dbus on the color control gx. Looking into mqtt now, and I was wondering if anyone wants to help out. I am not experienced in this field so it is a learning process for me. I want to end up with a guide for others to use that has the same or similar goals. Anyone interested?

Hey @Drogos! Nice project. You'll probably be quite happy to see this:

https://github.com/victronenergy/venus-docker-grafana

It has all you need, including influxdb & Grafana.

Got it installed! It works great! Thank you so much for the link, was unable to find this one in all my searching. Would you happen to know how this image talks to the mqtt to populate the db? Personally I want to set this up without using docker, and to learn, and know how every part of the system works. I can probably find that out from this great package, but a hint in the correct direction is nice if someone has it :)


btw, it worked amazingly well! Just clicked autoconfig, and it detected and set everything up perfectly. I strongly recommend this to anyone else reading this post that is not obsessed by setting up everything manually.

It works by using telegraf’s mqtt plugin.

It is much easier/cleaner/more complete to set that up than to do it manually with dbus and a cron job — just a few lines of configuration, and you need a mechanism to make sure Venus’s MQTT keeps alive.

Good luck!

Are you sure? I have been looking over all the sources I could find, and I could not find anything related to the telegraf plugin. Did manage to set it up with telegraf, but not well. To me it looks like it is using node.js to do the job. Anyone able to point me in the right direction for where this happens?

I solved this problem without docker and without VenusOS. Here are all the details: https://masterov.blogspot.com/2020/03/connect-vedirect-to-raspberry-pi.html

Let me know if you have any questions.
