What is ZigBee? The unsung hero of smart home systems and 5 key differences to Wi-Fi.

Have you purchased and installed a smart switch or smart plug for your home, only to find it stopped working after a while? Or did your entire home automation system cease to function when your internet connection was interrupted? The problem may not be with you, but rather with the communication protocol in use.

The answer to this question, which we frequently encounter in the smart home projects we carry out in Ankara, lies in one word:

In this article, the Enoras development team avoids complicated technical terms and explains what Zigbee is, why it is preferable to Wi-Fi, and how it transforms your home into a complete security fortress.

What is ZigBee? (Simply explained)

Technically, ZigBee uses the IEEE 802.15.4 standard, a low-power, short-range wireless communication language with a locking mechanism.

You can imagine it like this:

• Wi-Fi network

• Regarding the technology

The ultimate showdown: Zigbee or Wi-Fi?

This is one of the most frequently asked questions on Google: Why is ZigBee technology recommended over the widely used Wi-Fi when setting up a smart home? Here's a comparison based on Enora's experience:

Special feature	Smart devices with Wi-Fi technology	Smart devices with ZigBee technology
Energy consumption	Battery consumption is high (battery-powered devices discharge quickly).	Its capacity is extremely low (a single battery lasts a maximum of two years).
Network structure	The center (connected to the modem)	Networked system (devices are connected to each other)
Internet addiction	The system may stop working if the internet connection/modem fails.	It is still operational on the local network.
Coverage area	The limitation lies in the strength of the modem signal.	Each new device expands the coverage area.
Installation speed	A separate password must be entered for each device.	It is added via the dispenser within seconds.

ZigBee's superpower: Interlocking network technology

The biggest advantage of the ZigBee system lies in its network architecture. Every ZigBee device in your home (e.g., a smart plug or a smart switch) will also work.

For example, if your modem is in the living room but your smart lamp in the bedroom doesn't detect it, a Zigbee motion detector or a smart plug in the hallway will pick up the signal and relay it to the bedroom. Even if one device fails, the system automatically repairs itself and sends the signal via another device.

Opinion of the Inuras experts:

What is the purpose of a ZigBee hub (gateway)? And is it necessary?

Yes, you need a "hub" or "gateway" to use ZigBee devices. But why?

Your smartphone doesn't support the ZigBee protocol, only Wi-Fi. Your smart key, however, does support ZigBee. These two devices need a communication interface – and that's exactly where this product comes in.

This measure prevents 50 different devices from connecting to your modem, which slows down your internet speed. Only one router is connected.

The most important question: Will Zigbee still work if the internet fails?

Answer:

Unlike cloud-based Wi-Fi devices, most Zigbee automation processes are handled locally on the hub device.

For example, let's say you set up a scenario where a motion detector switches on a light when you are present. Even if your internet connection fails, the sensor sends a signal to the Zigbee router, which then switches on the light. Your security and comfort are not affected by the internet outage.

Which brands use ZigBee technology?

ZigBee is a global language. However, the following ecosystems are the most widely used in terms of compatibility:

• Tuya / Smart Life:

• Sonoff (Zigbee models):

• Phillips Hue:

• Samsung SmartThings:

At Enoras, we generally prefer the use of ZigBee-based industrial infrastructure.

In summary: The right decision for your home in Ankara

If you only need one or two smart plugs, Wi-Fi devices may suffice. However;

• Making the entire house smart,

• Heating, lighting and security management from a central point.

• If you want to build a system that remains unaffected by internet outages,
