Thanks all.

I’ve edited my code to tidy it up ad make it a bit more structured.

#!/usr/bin/python import RPi.GPIO as GPIO import time import os # First button - Lights Toggle but1 = 4 led1 = 13 def ltoggle(): print('Button 1 Pressed - toggling the Lounge Lights') os.system('curl admin:admin@172.0.0.250:8080/api/device/LLM-01-50-C7-BF-43-0F-34/toggle') # Second button - Lights Dim but2 = 17 led2 = 26 def ldim(): print('Button 2 Pressed - dim the rear lights') os.system('curl admin:admin@172.0.0.250:8080/api/device/brightness-full/buttonPressed?buttonId=LightsDim') # Third button - Lights Full but3 = 27 led3 = 19 def lfull(): print('Button 3 Pressed - rear lights on full') os.system('curl admin:admin@172.0.0.250:8080/api/device/brightness-full/buttonPressed?buttonId=LightsFull') # Fourth button - TV Toggle but4 = 6 led4 = 5 def tvtoggle(): print('Button 4 Pressed - toggling the TV on and off') os.system('curl admin:admin@172.0.0.250:8080/api/device/LL-01-50-C7-BF-76-E5-FE/toggle') # Status LED StatLed = 21 # Define LED sequence def butled(led): GPIO.output(led, 1) time.sleep(3) GPIO.output(led, 0) # Define flash LED def flashled(led): GPIO.output(led, 1) time.sleep(0.4) GPIO.output(led, 0) time.sleep(0.4) GPIO.output(led, 1) time.sleep(0.4) GPIO.output(led, 0) time.sleep(0.4) GPIO.output(led, 1) time.sleep(0.4) GPIO.output(led, 0) time.sleep(0.4) GPIO.output(led, 1) time.sleep(2) GPIO.output(led, 0) # Define GPIO Pins GPIO.setwarnings(False) GPIO.setmode(GPIO.BCM) GPIO.setup(but1, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(but2, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(but3, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(but4, GPIO.IN, pull_up_down=GPIO.PUD_UP) GPIO.setup(led1, GPIO.OUT) GPIO.setup(led2, GPIO.OUT) GPIO.setup(led3, GPIO.OUT) GPIO.setup(led4, GPIO.OUT) GPIO.setup(StatLed, GPIO.OUT) # Main Loop try: while True: GPIO.output(StatLed, 1) input_state = GPIO.input(but1) if input_state == False: ltoggle() time.sleep(0.2) flashled(led1) input_state = GPIO.input(but2) if input_state == False: ldim() time.sleep(0.2) flashled(led2) input_state = GPIO.input(but3) if input_state == False: lfull() time.sleep(0.2) flashled(led3) input_state = GPIO.input(but4) if input_state == False: tvtoggle() time.sleep(0.2) flashled(led4) except KeyboardInterrupt: GPIO.cleanup() GPIO.cleanup()

The issue I have now is that python is maxing the CPU out waiting for a command. I did try briefly to use interrupts but I can’t seem to get it to run in a loop Can anyone help me with that please? As I said, I’m not a programmer.
