PiRelay Power Relay Module for Raspberry Pi, 4 Channel Relay

I am using this with a 3b+ with Hoobs and a garage door Homebridge Plugin. Works really well.
I wrote a python script that you can copy/paste and run that tests each relay.
Keep in mind that typically apps on the RPi will use GPIO assignment numbers and not physical pins. So this python uses the physical pin number only. Copy everything below.

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)

GPIO.setup(7,GPIO.OUT)
GPIO.output(7,GPIO.LOW)

GPIO.setup(11,GPIO.OUT)
GPIO.output(11,GPIO.LOW)

GPIO.setup(13,GPIO.OUT)
GPIO.output(13,GPIO.LOW)

GPIO.setup(15,GPIO.OUT)
GPIO.output(15,GPIO.LOW)

try:
GPIO.output (7,GPIO.HIGH)
print (“First Relay ON”)
time.sleep(2)
GPIO.output (7,GPIO.LOW)
print (“First Relay OFF”)
time.sleep(2)
GPIO.output (11,GPIO.HIGH)
print (“Second Relay ON”)
time.sleep(2)
GPIO.output (11,GPIO.LOW)
print (“second Relay OFF”)
time.sleep(2)
GPIO.output (13,GPIO.HIGH)
print (“Third Relay ON”)
time.sleep(2)
GPIO.output (13,GPIO.LOW)
print (“Third Relay OFF”)
time.sleep(2)
GPIO.output (15,GPIO.HIGH)
print (“Forth Relay ON”)
time.sleep(2)
GPIO.output (15,GPIO.LOW)
print (“Forth Relay OFF”)
time.sleep(5)
GPIO.cleanup()
print(“ALL OFF….. Good Bye !!!!”)
except KeyboardInterrupt:
print(“QUIT”)
GPIO.cleanup()
