SmartLife App DocsHow many sub-devices can I connect to a Bluetooth gateway/Zigbee gateway?
Learn about the maximum number of sub-devices that can be connected to Bluetooth and Zigbee gateways.
Understanding the device connection limits for your smart home gateways is essential for planning your network topology.
Bluetooth Gateway Capacity
In theory, up to 128 sub-devices can run stably under the Bluetooth gateway at present, but due to the mutual interference between Bluetooth devices and the limitation of the connection distance (within 5 meters), the theoretical value of 128 may not be reached.
Practical Considerations: The actual number of devices you can connect may be lower than the theoretical maximum due to environmental factors such as interference and distance limitations.
Zigbee Gateway Capacity
The capacity of Zigbee gateways varies depending on the gateway type:
- Wired Zigbee Gateway: In theory, up to 128 sub-devices can be stably operated under the wired Zigbee gateway.
- Wireless Zigbee Gateway: Up to 50 sub-devices can be stably operated under the wireless Zigbee gateway.
Important: The maximum number of connected devices may be affected by network conditions, device types, and environmental factors. For optimal performance, it's recommended to stay within these limits.
