Im trying to get my neopixel to work but I keep getting the error: node-red:rpi-gpio.status.not-available.
I'm using a raspberry pi 4 with a fresh install of the default os.

Does anyone know how I can fix this or what could be the cause?

There is a bit more stuff you have to do in the RasPi setup.

Alas that machine is now offline and I can't boot it. Sorry.

This may help - I hope:

Last post.

It seems that you need these 4 lines:

hdmi_force_hotplug=1
hdmi_force_edid_audio = 1
hdmi_group=2
hdmi_mode=39

I was recently (as in very) messing around and the LEDs stopped working again.
This is/was because I use VNC and had changed the resolution of the screen to better fit the monitor.
When I looked at the /boot/config.txt the hdmi_mode and hdmi_group were set to something else.
Putting them to what is shown, the LED's started to work again.

Did you install the Pre-requisit?
