What Is Zigbee?
Zigbee is a wireless standard enabling low-power, secure connections between smart devices. Widely used in home automation for devices such as thermostats, sensors, and locks, its energy efficiency allows some devices to operate for years on a single coin cell battery.
One of Zigbee’s greatest advantages is its local nature – no need for cloud subscriptions or even an internet connection. Everything can remain within your home, ensuring high security and resilience against internet outages.
Top brands like IKEA, Philips Hue, Tuya, and Sonoff offer Zigbee-supported devices. This allows you to combine products from various manufacturers into one smart home setup, ensuring 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. Its robust security features, including encryption and key protection, safeguard your smart home and keep it under your control.
