Relay connection to gpio - wifi75 - 2017 Sep 15
Hello, where is the guide for connection relay module directly to correct gpio pin ?
RE: Relay connection to gpio - dan - 2017 Sep 15
That would be the documentation for the relay_board plugin:

Very good
thank you!

May I rephrase the question possibly? I am seeking the same. However the documentation refers to old 26 pin header and GPIO,,,Most of my 40 pin headers are already reserved for other items, I need to find out where to CHANGE the hardcoding to point say Station 01 to GPIO 16 or whatever other I choose?

If you are using the relay_board plugin the pins are defined in SIP/plugins/relay_board.py line 55.
If you are using a shift register interface the pins are defined in SIP/gpio_pins.py starting on line 95.
You can get a large number of stations while using only a few GPIO pins with a shift register interface such as the one described in the SIP wiki:

This works best with high level trigger type relays.

Hi all,
Thank you for a great piece of software. Im having issues with making the relays work - they dont move at all. Using Pi3b+.
I am using an 1 Relay module, which works great if I trigger it from Terminal. It also turns on and off at starting or restarting SIP. However, when I click Run now or Run program now, it does not do anything. Ive tried all possible options at plugin settings and many different pins.
Could anyone tell me what am I missing here?
Thank you and have a great day.
EDIT: I also tried to run it from terminal and dont get any errors
EDIT2: Ive managed to solve the problem by changing the relay_16.py:
I had to comment out all the GPIO.output(relay_pins[i], GPIO.HIGH) (and LOW) and change them to GPIO.setup(relay_pins[i], GPIO.IN) (or OUT). Not the perfect way to do it, but the one that works. Could it be because of the RPi model?
