I’m only semi-computer literate - everything is trial and error and cut and paste and hours of google research… If the details include what software should be used and exactly what to type then I can usually muddle my way through. But when it comes to ‘just add a few lines of code in the xxx” I’m completely lost.
I have managed to burn an image to a sd card and install Venus Pi v2.60 large image on to a raspberryPi 3.
I have 1 Victron mppt 75/15 connected successfully to it vie ve-direct usb cable.
I have successfully got node-red running (and can even see it all via VRM Portal - including node-red which is amazing).
I’m still at beginnings of how node red works but can see its potential.
So far so good
But I’d really like to add more than 1 relay so I can control multiple external devices (like pumps, irrigation valves etc) and also control them through node red.
I’ve read the comments and half guides for adding extra relays - but they are incomplete or presume you know how to do certain un-explained steps. So I'm completely lost.
So - anyone have a step by step guide to add relays ? (and I’m on a Mac so Mac instructions would be great!)
Thanks in advance for all the amazing guides so far - and for the missing bits I hope someone will write soon…
I would like to install the ffmpeg package on venus OS with raspberry Pi.
This package is not included in the standard repository of Venus os, i tried:
opkg install ffmpeg
i also tried to find a correct package which has the .ipk archive, but no result.
Does anybody have succesfully installed ffmpeg package onto a raspberry Pi with Venus OS?
I have a Raspberry pi with Venus OS large and would like to write data to a USB stick plugged into the Pi using Node Red. Unfortunately I couldn't find out what the path of the USB stick is, and all Linux commands don't work to find it out. can someone help me?
Where might I find the Modbus registers for the Extra relays the Raspberry pi has? I have looked in the Excel Modbus-TCP register list, but can only find Relay 1 and 2.
I used the RpiGPioSetup add-on to assign the extra relays. I can see and control the extra relays using Remote Console.
I currently have NodeRed running on external device controlling Relay 1 and 2. I am looking to control the other relays (3-6). NodeRed is also pulling data from my BMV-712 / other Victron items.
Hallo Powerlovers ;) ,
komme leider nicht mehr weiter und hoffe hier ein paar Anregungen zu bekommen.
Hatte bisher folgendes Setup in meinem, in die Jahre gekommen Wohnmobil.
Raspberry Pi mit:
Nun hab ich mir den Victron SmartSolar Charger MPPT gegönnt und dachte ich könnte den problemlos über die USB Verbindung in Node-Red einbinden aber entweder finde ich nicht die passenden "Librarys“ um den Charger in Node-Red nutzen zu können oder es funktioniert nur über die Venus OS?
Nun habe ich Venus OS auf einer frische SD Karte installiert und der Charger wird sofort erkannt. Nun fehlen mir die folgenden Möglichkeiten die ich zuvor hatte.
Ist es möglich die folgenden Anwendungen in Venus OS zu realisieren?
Bin über jeden Hinweis Link usw. dankbar
Raspberry pi 3B+, VenusOS Large V280.11/20
I clicked "update to 1.4.2" by the victron energy nodes in the node-red palette. I currently have 1.4.1 installed and working. The installation failed with the following output in the event log:

When I ssh into the raspi and go to the node_modules directory I see that @victronenergy is not a directory but a file with 0 bytes. The file config.nodes.json file, however, seems to point to "/usr/lib/node_modules/@victronenergy/node-red-contrib-victron/src/nodes/config-client.js" so maybe that's why the update do not work.
My question is, how do I make it work without screwing something up? :)
Following the notes from here I've managed to get as many relays as I want configured on my RPi. These work on the GUI and in hardware.
The problem I'm having is that if I configure more than two relays, they stop apprearing as an option for me to control in Node-Red. Has anyone had a look at this or have a work around?
All of a sudden when I go to Venus.local:1880 a screen comes up requiring username and password
i don’t believe I did anything to set this up and I don’t know what the username and password is
is there a default or a way to stop this happening ?
I am looking for a Venus OS Raspberry image with integrated Node-Red in the latesed version Venus 2.60~16.
Is there someone working on it? I found an older Version from mpvader.
Thanks for your help!
