Now, when i push the 4th button on my pifacedigital2, it sends a web request that disables ad blocking for 5 minutes.

piholekiller.py

# idea from here https://www.reddit.com/r/pihole/comments/81z8jp/temporarily_disable_pihole_using_a_bookmarked_url/
import requests
import pifacedigitalio as p
import time


pd = p.PiFaceDigital()

def main():
    auth = 'PWHASH'
    while True:
        if pd.switches[3].value == 1:
            r = requests.get('http://pihole/admin/api.php?disable=300&auth={}'.format(auth)).json()
            try:
                if r['status'] ==  'disabled':
                    r = list(range(0, 8))
                    for x in r:
                        pd.leds[x].turn_on()
                        time.sleep(0.1)
                        pd.leds[x].turn_off()
            except:
                pd.leds[1].turn_on()
                pd.leds[1].turn_off()
                pd.leds[2].turn_on()
                pd.leds[2].turn_off()
                pd.leds[3].turn_on()
                pd.leds[3].turn_off()
