#!/usr/bin/python

import bluetooth
import time
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)
RELAY = 23
GPIO.setup(RELAY, GPIO.OUT)

while True:
    print "Checking " + time.strftime("%a, %d %b %Y %H:%M:%S", time.gmtime())
    result = bluetooth.lookup_name('78:7F:70:38:51:1B', timeout=5)
    if (result != None):
        print "User present"
        GPIO.output(RELAY,1)
    else:
        print "User out of range"
        GPIO.output(RELAY,0)

    time.sleep(10)

HI! Thanks for this idea! How would you add more than one phone that triggers the relais?
Thanks!

Is it possible to convert this to MicroPython to work on the ESP32?
Thanks.
