Can anyone tell me if I can use the Cerbo GX USB port to communicate with Arduino Nano or any other models?
Or do I have to add the Node-RED user to the group that owns the USB port, as I have read somewhere else?
Thanks
Just did a small test with an ep32 using the serial in and out in node red. It works, I am going to experiment a bit more and see how far it goes
Thanks, It sounds promising, but why the EP32? Did you have to go through the MQTT broker?
When I test Node-Red on Arduino from my MAC it works fine, however, if I connect to Cerbo’s USB port it doesn’t even see Arduino.
I researched and it seems that Venus uses a propriety protocol so how would the EP32 come into play here?
I did it over usb. Just had to workout where it was, like /dev/ttyUSB0 and it worked. I do use other esp devices over mqtt. Edit: should note I logged into Venus os to check if it was recognised
I have no previous experience with logiin into venus, did you do this from the VRM portal?
I had enabled Superuser and enabled SSH on lan

Thanks for the tips, I didn’t need to use SSH however I’ve installed it for the furure.
It was me being silly not knowing the correct node-red port for arduino so I was testing the system with the Mac port [/dev/tty.usbserial-1420] but you gave it to me [/dev/ttyUSB0]
I works perfectly now so I can create multiple digital outputs and control relays and all sorts of other devices.
