What is zigbee and why it is best for smart home devices

If you use a smart home technology in your home, then this technology is likely to use the zigbee protocol. Zigbee is a wireless communication protocol, a low-power local area network protocol based on the IEEE820.15.4 standard. Regulated in accordance with international standards, zigbee technology is a short-range, low-power wireless communication technology that supports a variety of smart home devices, from thermostats to refrigerator light bulbs.

What is Zigbee?

If you use a smart home technology in your home, then this technology is likely to use the zigbee protocol. Zigbee is a wireless communication protocol, a low-power local area network protocol based on the IEEE820.15.4 standard. Regulated in accordance with international standards, zigbee technology is a short-range, low-power wireless communication technology that supports a variety of smart home devices, from thermostats to refrigerator light bulbs.

Zigbee is set by the zigbee alliance, which includes Amazon, Samsung, Huawei, Qualcomm and Toshiba. What’s more, it is rapidly becoming the wireless protocol standard used by smart home devices to communicate.

How does Zigbee work?

Smart devices require wireless communication to receive commands from smart home hubs and associated apps, and pass information back to those hubs and apps. These devices might be able to use Wi-Fi, and some do, but it’s far from ideal.

There are several reasons for this: First, Wi-Fi consumes a lot of power, which is not good for low-power devices such as battery-powered or light bulbs; second, with too many devices on a home network, performance Not stable enough; again, range can also be an issue in larger homes.

And Zigbee has several advantages in this regard: first, it consumes less power than Wi-Fi; second, it is designed to support hundreds of devices on the network, although a single center may support far fewer devices than this ; On top of that, Zigbee uses a different kind of network called a mesh network. Each Zigbee device can be connected through another Zigbee device, rather than connecting directly to a hub like Wi-Fi, which transmits packets back and forth between the two. With Zigbee, these packets can be relayed by multiple devices in transit.

This mesh structure means that as long as different devices remain within range and connected to each other, they can communicate with the hub even when placed far away from the hub. If the grid is in the middle, you can have Zigbee devices scattered all over the house, or even in the garden, and if one device fails or loses power, it doesn’t matter because other nearby Zigbee devices can fill in the missing link.

Why is Zigbee important?

Zigbee is useful because it’s designed for interoperability, so one manufacturer’s light bulb or thermostat can still communicate and operate with another manufacturer’s device. It also means that one manufacturer’s switches or motion sensors should work with another manufacturer’s light bulbs or security cameras. But why do you say “should”? This is because some zigbee devices are still not very compatible with other zigbee devices, which is a point that needs to be improved now.

Another interesting thing about Zigbee is that you can use a variety of different devices from different manufacturers without requiring each device to have a specific hub, but if they all operate on the same 2.4GHz band, Problems will arise.

For example, some Zigbee bulbs and thermostats will connect directly to Samsung’s SmartThings hub, while many bulbs and hubs built into the Amazon Echo Plus or second-generation Echo Show will also connect directly to Samsung’s SmartThings hub. This makes the Echo Plus or SmartThings a nice, affordable way to get smart home tech compared to a separate hub.

Is Zigbee the only option?

The answer is no, some manufacturers use Wi-Fi because it works directly with the router and doesn’t require a special hub. While there is a competitor wireless protocol – Z-Wave that does the same thing, but operates on a different frequency band, it cannot interfere with Wi-Fi (although in practice, this is not an issue for wireless personal area networks). Samsung’s SmartThings hub will support both protocols, and some expect Bluetooth Low Energy to take over in the future, as mesh networking is part of its specification, but for now, it’s “Zigbee.”
