What Is Zigbee?
Zigbee is a wireless standard enabling low-power, secure connections between smart devices. Widely used in home automation for devices like thermostats, sensors, and locks, its energy efficiency allows some devices to run for years on a single coin cell battery.
The standout feature of Zigbee is its local operation – no cloud subscriptions or internet connections are required. Everything stays within your home, making it highly secure and resilient against internet outages.
Major brands such as IKEA, Philips Hue, Tuya, and Sonoff support Zigbee devices, allowing you to integrate products from various manufacturers into one system. This ensures you’re not locked into a single vendor – brilliant!
With an indoor range of 10–100 metres and extended outdoor coverage, Zigbee’s mesh networking ensures reliable communication, even if some devices go offline. Robust security features, including encryption and key protection, safeguard your smart home and keep it under your control.
