I need your help.
I’m using Ubuntu Core and running it on a Raspberry Pi 3 B+ machine. I have installed on it the snaps Openhab-ondra and Nodered.
I would like to control the GPIOs of my Raspberry using Nodered but I can’t figured it out how to do. I installed even the snap pigpio and the classic mode with RPi.Gpio and WiringPi but still can’t manage to get work my GPIOs via Nodered.
As you can see this image below from my Nodered, both Gpio nodes in input and output are grey and not available. In this way unfortunately I can’t control them and I’m totally stuck.
Instead, I can control the GPIOs from the terminal connecting one of them to the snap pigpio and give them the impulse with the http command (I followed this guide: http://www.om26er.com/2019/01/control-gpio-pins-on-raspberrypi-3.html)
It’s a start but what I need to do is to control them with Nodered.
I hope some of you can help me.
Thanks for your help,
