The Sonoff ZBDongle-P is a Zigbee 3.0 USB dongle designed to act as a central hub for your smart home network. Built around the Texas Instruments CC2652P chipset and utilizing a CP2102(N) USB-to-serial chip, it comes pre-flashed with Z-Stack 3.x.0 coordinator firmware to get you started quickly. The device features an RF output gain of +20dBm and an external SMA interface antenna, which helps maintain a stable connection across your devices. To ensure reliable performance, the internal components are housed in an aluminum alloy case that reduces signal interference. This compact unit measures 4.37 x 1.61 x 0.75 inches and weighs approximately 37g, making it unobtrusive when plugged into your hardware. Depending on your needs, you can switch the device between coordinator and router modes to better manage your network topology. This dongle is a practical choice for users running Home Assistant (ZHA), Zigbee2MQTT, or Jeedom. It allows you to integrate a wide variety of Zigbee sensors and switches into a single, unified system, providing a flexible foundation for those who prefer to manage their home automation locally.
