Node-RED Addon not detecting is a Raspberry system

Third party integrations Node-RED

Hello guys.

I have read on this forum about some issue when trying start Node-RED Addon with RPi.GPIO library.
But not have success.

My Rpi4 System:

~# uname -a
Linux FIFUrpi 5.10.0-9-arm64 #1 SMP Debian 5.10.70-1 (2021-09-30) aarch64 GNU/Linux

~# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:        11
Codename:       bullseye

I have rpi-gpio packets installed… :\

should be an Addon/Core issue, or a RPi.GPIO library issue?

2

I am having this same problem on a system that is not a raspberry-pi, and I didn’t added such library. Seems it is there by default. Is a bug?

3

Can I say. If I disable gpio pallet nodes (node-red-node-pi-gpio 2.0.1) from Pallet. Of corse will not return any error

Try adding it to your config on the addon page

npm_packages:
  - node-red-node-pi-gpio

Thank you for your answer.

Where I should run the suggested commands? :expressionless:

After some searching, gpio does not work with the addon. Gpio’s have to be set up through home assistant, then you can use service calls from nodered to control them.

Thank you for answer, but i am a newbie on this, how can i do that? some tips?

Dependent on which device you would look for it by name either in integrations or the forum.

Like one wire sensors or i2c sensors. It’s kinda limited.

If you dont find a match, esphome is the do it yourself platform in HA. It runs on cheap esp micro controllers ~$5 and supports a wide range of sensors.

Understand. enabling I2C. I have enabled before.

~# i2cdetect -l
i2c-3   i2c             bcm2835 (i2c@7e804000)                  I2C adapter
i2c-1   i2c             Broadcom STB :                          I2C adapter
