Turning on the Lights with a Clap Using Python and the Home Assistant API

After trying Google Home and Alexa, I wondered if I could turn on the lights by clapping. I already had Home Assistant running at home, so I wrote a program using its API. When I clap twice, the program checks whether the light is on or off and toggles it. You can also configure different actions for different numbers of claps.

Here's how the project describes Home Assistant: Home Assistant is an open-source home automation platform running on Python 3. Track and control all devices at home and automate control. Perfect to run on a Raspberry Pi. Official website: https://www.home-assistant.io/ GitHub page: https://github.com/KrunkZhou/PI-Clap Code:

import pyaudio import sys import threading import time from time import sleep from array import array import KRUNKHOMEAPI as kapi import homeassistant.remote as koapi #You will need to download homeassistant python api

def main(): kapi.api=koapi.API('sample.com', 'password','8123') # HA-API:domain, password, port check=kapi.apicheck() if check: start() kapi.endscript()

clap = 0 wait = 1 flag = 0 pin = 24 exitFlag = False

def toggleLight(c): domain = 'light' #domain switch_name = 'light.lamp' #switch name print (str(kapi.get_state(switch_name))) lamp=kapi.get_state(switch_name) if (lamp.state=='off'): kapi.turn_on(domain,switch_name) else: kapi.turn_off(domain,switch_name) sleep(1) print("Light toggled")

def waitForClaps(threadName): global clap global flag global wait global exitFlag global pin print ("Waiting for more claps") sleep(wait) if clap == 2: print ("Two claps") toggleLight(pin)

elif clap == 3:

print "Three claps"

#elif clap == 4: #exitFlag = True print ("Claping Ended") clap = 0 flag = 0

def start(): global clap global flag global pin
