Zigbee is generally a reliable wireless protocol for smart lighting. It operates on a self-healing mesh network where devices relay each other’s signals, ensuring a stable connection even in larger homes. How reliable Zigbee is in your situation depends on the number of devices, the layout of your home, and any potential sources of interference in the vicinity. In this article, we answer the most frequently asked questions about Zigbee, from range and interference to how it compares with other protocols.
How stable is a Zigbee connection in practice?
In practice, a Zigbee connection is very stable, especially when there are multiple Zigbee devices in the home. Zigbee operates via a mesh network: every device that is powered acts as a relay for signals from other devices. The more devices there are, the more robust the network becomes.
In an average household with a handful of smart bulbs, a Zigbee dimmer, and a central hub—such as a Zigbee coordinator—the connection works virtually without interruption. Devices typically respond to commands within a fraction of a second, making the experience smooth and responsive.
The network also automatically recovers if a device temporarily goes offline or is moved. Zigbee then independently finds an alternative route without you having to do anything. This makes the protocol particularly well-suited for everyday use in homes.
What are the most common causes of Zigbee malfunctions?
Zigbee malfunctions are most often caused by interference from other wireless networks, devices being too far apart, or a network that is too small with too few relay points. In most cases, these issues can be easily resolved by adjusting the placement of the devices.
Here are the most common causes:
- Wi-Fi Interference (2.4 GHz): Zigbee operates in the same frequency range as most Wi-Fi networks. A busy Wi-Fi channel may overlap with Zigbee channels and cause interference. It is best to choose a Zigbee channel that overlaps as little as possible with your Wi-Fi channel.
- Not enough devices on the network: With only one or two Zigbee devices, there is no mesh network. Signals must then travel directly to the hub, which can cause problems over longer distances.
- Physical obstacles: Thick concrete walls, metal structures, or underfloor heating can weaken the signal.
- Poorly placed hub: A Zigbee coordinator that is too far away from the devices or is located behind a metal cabinet will not work as well.
How far does a Zigbee signal reach inside a home?
In open space, a Zigbee device has a range of approximately ten to twenty meters. Inside a home, with walls and other obstacles, the effective range per device averages five to ten meters. Thanks to the mesh principle, the total range of a Zigbee network is, in practice, much greater than that of a single device.
In an average-sized townhouse or apartment, Zigbee’s range is usually more than sufficient. In a larger home or one with many load-bearing walls, it’s a good idea to strategically place Zigbee devices throughout the rooms. Any device that is permanently powered, such as a built-in dimmer or a smart switch, automatically boosts the network.
With a well-designed network and enough devices, Zigbee can easily cover multiple floors or a garden. This makes the protocol suitable for larger homes or buildings as well.
What is the difference between Zigbee, Z-Wave, and Wi-Fi for smart lighting?
Zigbee, Z-Wave, and Wi-Fi are all wireless protocols used for smart lighting, but they differ significantly in design, range, and energy consumption. The main difference is that Zigbee and Z-Wave operate via a mesh network and consume very little energy, while Wi-Fi connects directly to your router but requires more power.
An overview of the main differences:
- Zigbee: Mesh network, low power consumption, operates at 2.4 GHz, requires a hub or coordinator, widely supported by brands such as Philips Hue and IKEA.
- Z-Wave: Also a mesh network, it operates on a different frequency band (868 MHz in Europe), resulting in less interference with Wi-Fi, but the range of products is more limited than with Zigbee.
- Wi-Fi: No additional hub is required, but it puts a greater strain on your home network, consumes more energy per device, and is less suitable when many devices are connected at the same time.
For smart lighting, Zigbee is the most practical choice in most homes: it combines a wide range of products with a stable network and low power consumption per device.
Does Zigbee work with Philips Hue, Homey, and KlikAanKlikUit?
Yes, Zigbee is compatible with Philips Hue, Homey, and KlikAanKlikUit, because all of these platforms support the Zigbee protocol. This makes it easy to have devices from different brands work together within a single smart home system.
Philips Hue uses its own Zigbee implementation via the Hue Bridge, which can also control devices from other brands, provided they are Zigbee-compatible. Homey is a versatile hub that natively supports Zigbee and can therefore integrate a wide range of devices, regardless of brand. KlikAanKlikUit also offers Zigbee products that work with standard Zigbee hubs.
This is a major advantage of Zigbee: you’re not tied to a single brand or ecosystem. You can expand your existing setup with new products from other brands, as long as they all use Zigbee. This makes Zigbee a future-proof choice for anyone who wants to build a smart home system step by step.
When is Zigbee the right choice for your smart lighting?
Zigbee is the right choice if you want a reliable, energy-efficient, and scalable system that works with multiple devices and brands. It’s particularly well-suited if you already use Philips Hue, Homey, or KlikAanKlikUit, or if you want to control a large number of smart lights from a single central hub.
Zigbee is less suitable if you only want to control one or two individual lights without an additional hub. In that case, a simple Wi-Fi light or Bluetooth solution might be more practical. But as soon as you want to automate multiple rooms or integrate them with other smart devices, Zigbee clearly offers greater stability and flexibility.

Frequently Asked Questions
Do I need a hub to use Zigbee lighting?
Yes, for most Zigbee devices, you need a Zigbee coordinator or hub, such as a Philips Hue Bridge, Homey, or a standalone Zigbee coordinator (for example, one based on Zigbee2MQTT). Without a hub, Zigbee devices cannot connect to your smartphone or home network. An exception to this are some Bluetooth-controlled lights that also support Zigbee, but a hub is strongly recommended for a complete and stable network.
How do I fix a Zigbee device that loses connection or stops responding?
Start by checking the distance between the device and the nearest hub or another Zigbee device acting as a relay. If necessary, add an additional Zigbee device between the hub and the problematic device to strengthen the mesh network. Also check whether your Wi-Fi router is operating on a channel that overlaps with the Zigbee channel, and adjust this if possible. If the problem persists, it sometimes helps to remove the device from the network and pair it again.
Can I use Zigbee devices from different brands together in a single network?
In most cases, yes, but there are some nuances. Zigbee is an open standard, which means that devices from different brands are technically compatible. In practice, brands like Philips Hue, IKEA, and KlikAanKlikUit work well together via a universal hub like Homey or a Zigbee2MQTT setup. Please note that some brands, such as Philips Hue via its own Hue Bridge, impose restrictions on third-party devices. If you use an open platform like Homey, you’ll have the most flexibility.
What is the maximum number of Zigbee devices I can connect to a single network?
A Zigbee network can theoretically support up to 65,000 devices, but in practice, the limit is determined by the capacity of your hub or coordinator. Most consumer hubs, such as the Philips Hue Bridge, support between 50 and 100 devices. For an average home, this is more than enough. If you want to set up a larger system, an open Zigbee coordinator combined with Zigbee2MQTT offers greater scalability.
Is Zigbee secure enough for use in my home?
Yes, Zigbee uses AES-128 encryption for communication between devices, which provides a high level of security for home use. Messages transmitted via the mesh network remain encrypted, making interception by third parties virtually impossible. Just make sure your hub or coordinator is up to date with the latest firmware so that known security vulnerabilities are patched in a timely manner.
Will Zigbee still work if my internet goes down?
Yes, Zigbee works without an internet connection for its basic functions. Communication between Zigbee devices and the hub takes place locally, via your home network. This means you can still control lights and dimmers using an app on your local network or physical switches, even if your internet connection goes down. However, features that rely on cloud services—such as voice control via Google Assistant or Alexa—will not work in that case.
What is the difference between a Zigbee router and an end device?
Within a Zigbee network, there are three types of devices: the coordinator (the hub), router devices, and end devices. Router devices, such as built-in dimmers and smart switches that are always powered, relay signals to other devices, thereby strengthening the network. End devices, such as battery-powered sensors or remote controls, only send signals and do not act as relay points. For a strong mesh network, it is therefore a good idea to install enough devices with a permanent power connection, such as Zigbee dimmers, in your home.
