Built for a More Flexible Smart Home The SONOFF Dongle Plus MG24 is designed for users who want to bring compatible Zigbee devices from different manufacturers into one smart home environment. Instead of purchasing separate hubs for different Zigbee brands, the MG24 can act as a central Zigbee coordinator for supported open-source platforms. This makes it easier to build a customised system around your preferred software, devices and automation routines. Whether you are adding smart lights, sensors, switches, plugs or other compatible Zigbee products, the MG24 gives your setup a flexible foundation for future expansion. Powerful EFR32MG24 Performance At the centre of the MG24 is the Silicon Labs EFR32MG24 chipset with 1536KB Flash and 256KB RAM. SONOFF states that the MG24 provides 100% more Flash and 300% more RAM than its EFR32MG21 comparison, giving the device greater resources for demanding firmware and smart home applications. This additional processing capability is designed to support faster automation processing and quicker communication with Zigbee sub-devices, making it a strong choice for growing smart home networks. Enhanced Antenna for Reliable Connectivity The MG24 features an adjustable external antenna designed to improve wireless communication. The antenna provides 3dBi gain by default and can reach up to 4.5dBi when optimised by angle and channel. SONOFF lists a signal range of up to 200 metres in free line of sight, while actual indoor range will depend on walls, interference, building materials and network conditions. The adjustable antenna also allows you to direct the antenna towards connected devices for improved positioning and potentially more stable communication. Universal Zigbee USB Coordinator The SONOFF Zigbee USB Dongle Plus MG24 is designed to work as a universal coordinator for supported open-source smart home platforms. Compatible environments include: Home Assistant Zigbee2MQTT openHAB Other compatible open-source Zigbee platforms This gives you the freedom to create a multi-brand Zigbee ecosystem instead of being restricted to one manufacturer's hub. Flexible Firmware for Advanced Smart Home Setups The MG24 is not limited to one fixed operating role. Using the SONOFF Dongle Flasher, supported firmware can be installed to use the hardware for different applications. Depending on the selected firmware and configuration, the MG24 can function as a Zigbee Coordinator, Zigbee Router, OpenThread RCP or MultiPAN RCP. For advanced smart home users, this flexibility means the same hardware can adapt as your automation requirements develop. Zigbee and Thread Flexibility The MG24 supports Zigbee 3.0 and can also be configured for Thread-related applications using compatible firmware. SONOFF documents OpenThread functionality and configurations for connecting with a Thread Border Router and supporting Matter over Thread devices. It also documents a Zigbee and OpenThread two-in-one configuration for users who want to manage both technologies with compatible firmware and software. This makes the MG24 an appealing option for users who want flexibility as smart home standards continue to develop. Included 1m USB Extension Cable The included 1 metre USB extension cable gives you greater freedom when installing the coordinator. Rather than keeping the dongle directly beside a computer, Raspberry Pi or home automation server, you can position it further away from potential sources of electromagnetic interference. This can also make it easier to place the external antenna in a more suitable position for your Zigbee network. Durable Aluminium Alloy Housing The MG24 features an aluminium alloy housing designed to provide a compact and durable finish. SONOFF describes the housing as pressure-resistant and corrosion-resistant and states that it has undergone a 24-hour salt spray test. The result is a clean, compact USB coordinator designed to fit naturally into modern smart home installations. How to Use the SONOFF Dongle Plus MG24 Setting up the SONOFF Zigbee USB coordinator is straightforward when used with a compatible platform: Connect the MG24 to your Home Assistant server, Raspberry Pi, computer or other supported host using USB. Use the included USB extension cable if you need to move the dongle away from the host device. Install or configure your preferred Zigbee platform, such as ZHA or Zigbee2MQTT. Configure the MG24 as your Zigbee coordinator according to the platform's instructions. Put compatible Zigbee devices into pairing mode and add them to your network. Create automations and scenes through your chosen smart home platform. For ZHA, SONOFF's current documentation explains that users can configure the dongle and then add Zigbee sub-devices through Home Assistant. Who Is the SONOFF MG24 For?
