Home Assistant automation to detect motion on an Arlo security camera and turn a light on and off

In this tutorial, I will be showing you how to create an automation in Home Assistant to detect motion on an Arlo Security Camera and to turn the front door light on when motion is detected and off when motion is inactive. You can also follow me more closely on this YouTube video where I demonstrated line by line how to code the automation.

To code this smart home automation, I am using the Arlo Camera Support Integration and the Appdaemon framework integration in Home Assistant. Go ahead and configure both of those integrations.

Part I

First, I need to register my Appdaemon App in Home Assistant, as described in the video. My Apps.yaml file is as follows:

Arlo Motion:
  module: arlo_motion
  class: ArloMotion

Part II

The code for the automation is as follows:

import appdaemon.plugins.hass.hassapi as hass
class ArloMotion(hass.Hass):
	def initialize(self):
			self.listen_state(self.on_motion_detected, "binary_sensor.aarlo_motion_front_door", attribute = "state", new = "on")
	def on_motion_detected(self, entity, attribute, old, new, kwargs):
		if new == "on":
			self.turn_on("light.front_door_light")
		if new == "off":
			self.turn_off("light.front_door_light")

To test the automation, you should activate motion on your Arlo Security Camera and then observe whether the automation actually turns your designated light on and off.
