This document discusses using Home Assistant to build a smart home system. It introduces Home Assistant as an open-source platform that allows connecting various smart home devices and automating control of them. It describes how to set up Home Assistant on a Raspberry Pi, configure devices and sensors, and create automation rules. The document also covers integrating Home Assistant with other systems like Google Assistant and Amazon Alexa to control the smart home with voice commands.

13. ● Platforms
○ Types of devices (ex, lights, sensors)
● Components (> 1000)
○ Interact with an Internet-of-Things domain
■ MQTT, Zwave, Zigbee
■ Lights (Hue, Tradfri)
■ Sensors
○ Respond to events that happen within
Home Assistant
■ Small pieces of home automation logic or
involve services that do common tasks within
your house.
■ ex, device_sun_light_trigger component
