Zigbee and Zigbee2MQTT: Integration with Home Assistant

Introduction to Zigbee

• Zigbee is a wireless communication standard used by many smart device companies (e.g., Philips Hue, Amazon, Acara, Sonoff).
• Example: Pressing a button on a Hue dimmer switch sends a Zigbee signal to the Philips Hue hub, which then sends a signal to the Hue light bulb to turn on.
• More detailed information on Zigbee: Check out the provided video link in the description.

Issue with Multiple Hubs

• Different manufacturers require separate hubs and ecosystems despite using the Zigbee standard.
• Often requires signing up for cloud accounts, giving companies access to your data.
• Solution: Use Home Assistant to centralize control over Zigbee devices.

What is Zigbee2MQTT?

• Software that lets you control Zigbee devices using MQTT (lightweight messaging protocol).
• Example: Temperature sensor sends readings to MQTT broker; other devices can subscribe to receive updates or request the latest reading.
• Advantage: Scalability and fast communication among numerous devices.
• Works seamlessly with Home Assistant.

Why Use Zigbee2MQTT?

• Zigbee2MQTT vs. Zigbee Home Automation (ZHA): Both integrate Zigbee devices into Home Assistant without needing multiple hubs.
• Zigbee2MQTT offers more flexibility and supports a wider variety of devices.
• Initial Recommendation: Start with ZHA due to ease of use and installation.

Required Components

• Working Home Assistant installation.
• USB Zigbee coordinator: Lists of supported USB adapters available on the Zigbee2MQTT website.
• Zigbee USB extension cable: Prevents electronic interference.
• Note: Coordinator firmware should be chosen over router firmware when buying the USB stick.

Installation Steps for Zigbee2MQTT

Pre-Installation

1. Insert USB Coordinator: Plug into a spare port on your Home Assistant server.
2. Install MQTT Broker: Recommended is 'Mosquitto'. (Refer to linked video for detailed steps).
