Can my new 250/60 Controller read by two systems at the same time, an RPI based Venus and a CerboGX?

Node-RED

I am using a VE direct to USB to feed the Cerbo as it only has 3 VE ports (really?) I am setting up an Raspberry based system to test Node Red and want it to also see at least my new solar controller, if not all the rest of the devices. Currently I am searching for a Y USB splitter with a single female and dual male type A connections. I do have a CAN waveshare device available that I was using with my battery pack till I found a better way to connect it.

Has anyone tried this? I never experiment with a production system, but having the real data on both would be beneficial to me. -Bill

You can run a seperate nodered instance on a standalone device. Does not need a direct device connection, it uses IP to the GX. Instructions are on the victron nodered page.

Thanks for that, but I do not want to do anything to the production device. Is what I am asking impossible? I was an IT guy for a long time. Testing stuff on a production systems was the quickest way to become unemployed.

Not sure what you mean, but the GX just runs as a gateway for the renote nodered device.
You can’t split vedirect devices across multiple venus setups and you don’t need another venus install if you only want to use nodered on another device.

Ok. So it cannot be done.
Not sure what that not sure what you mean statement? Testing on prod systems or becoming unemployed…

You need a USB hub for more devices

Most Y Usb splitter are used for powering devices (no logic)

Be careful I use always a isolated USB adapter

You can’t connect multiple GX devices to a single vedirect charger, using a splitter does not change that.

Oeps, I read the question wrong

true

let me compare your wish with a PC:

  • You could connect 2 monitors to 1 PC, use them the same time
  • you can´t connect 2 PC to one monitor, use the 2 PC the same time

Actually if using Display port you should be able to.

really? what will this look like? 2 Pictures behind each other? Like a Windows Desktop behind a half transparent Linux Desktop?

I guess you mean a monitur with 2 inputs - never saw one where both could be used the same time except fancy things like 32:9 Ultra-Wide

You can share the data with MQTT
