Automate more than 2 relays using Node-Red on RPi

Hi

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.

https://community.victronenergy.com/questions/34195/make-more-than-two-relays-visible-on-rpi-rpi.html

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?


Thanks,


Dan

Node red login

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 ?

Add Relays - Does anyone have a an ‘idiots guide' on how to add more Relays to a VenusPi set up?

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…
