I want to use the GPIO pins of my Raspberry Pi to send simple HIGH/LOW signals to the digital pins on my Arduino so i can run a script and do a digitalread etc etc.
So when i put the component into my config file,
switch:
platform: rpi_gpio
ports:
11: Fan Office
invert_logic: false
i got the follow in my log
16-08-08 16:27:58 homeassistant.components.switch: Error while setting up platform rpi_gpio
Traceback (most recent call last):

for port, name in ports.items():
AttributeError: 'NoneType' object has no attribute 'items'
So this worked for getting rid of the error in my log file, but on the front end i still dont have a simple toggle that i thought that would give me to be able to trigger. Any suggestions?
You said in my config file i should refer to it under the ports: section as what it says under the BCM column when i do gpio readall, even though its named “gpio.7” and its physica number is “7”.
So why do i have to refer to it as its BCM number in the config file?
You do not refer to it as BCM in config.
The correct number is shown under BCM column when type “GPIO read all” in command line.
Your config was correct, just number was wrong. Maybe indent was wrong but I cannot confirm that.
So wait, in my config file under ports: i put “4” to refer to the circled GPIO pin (as shown in screenshot below).
Should it be refered to as “7” instead under ports:?
i tested it out by switching it on and off from the front end and then running “gpio readall” again and i can see it switch from “0” to “1” in the V column. so i know that by putting “4” in the config file, it switches the GPIO.7 pin high/low
