Zigbee is a low-power, wireless mesh communication protocol used extensively in smart home devices. It enables reliable, local device-to-device communication without relying heavily on Wi-Fi or the cloud.
A Brief History
Zigbee was introduced in the early 2000s and is based on the IEEE 802.15.4 standard. It was designed to provide simple, low-power wireless connectivity for short-range communication — ideal for sensors, lights, and switches.
Over the years, Zigbee has been adopted by hundreds of companies, leading to the creation of the Zigbee Alliance (now called the Connectivity Standards Alliance, or CSA), which also oversees Matter.
Key Benefits of Zigbee
