Zigbee: The Wireless Mesh for Home Automation
Zigbee is a low-power, low-data-rate wireless mesh networking standard. Unlike Wi-Fi, it’s designed for tiny battery-powered devices like sensors and switches.
Why Zigbee in the Lab?
- Mesh Networking: Every mains-powered device (like a smart plug or light bulb) acts as a “router,” extending the network’s reach.
- Privacy First: It’s local only. No cloud required to turn on your lights.
- Battery Life: Sensors can last for years on a single button cell.
NetYeti’s Implementation Stack
- Coordinator: The “Brain.” I recommend the Sonoff ZBDongle-E or SkyConnect.
- Controller:
- Zigbee2MQTT: Highly flexible, supports the most devices.
- ZHA (Zigbee Home Automation): Built directly into Home Assistant for easy setup.
Best Practices
- Interference: Keep your Zigbee coordinator away from your Wi-Fi router (they both use 2.4GHz).
- Placement: Distribute mains-powered “routers” throughout your house to ensure a strong mesh.
Knowledge Check:
- Are your Zigbee and Wi-Fi channels overlapping? (Check the channel mapping!)
- Have you secured your Zigbee network with a custom key?
