I have installed Home assistant in my Raspberry pi 3 and have add on Node red.
then in the Manage pallet installed "node-red-node-pi-gpio"
but after that if i use Gpio Out or In, i always see them as "Not applicable" or "NA"
no matter which tutorial i follow from youtube, for them its shows as OK or 0 or 1 but for me it always shows as NA
GPIO pins dont work for me
but i tried installing pure Raspian and wrote a small python script which successfully invokes the GPIO and eventually triggers the relay board switch.
but in Node red none of the GPIO pins work
