SONOFF Dongle Max (Dongle-M) Review – A Zigbee/Thread PoE, USB, and WiFi adapter tested with Home Assistant

SONOFF Dongle Max Dongle-M review with Home Assistant Zigbee2MQTT ZHA

SONOFF sent us a sample of the SONOFF Dongle Max (also known as Dongle-M) Zigbee/Thread adapter with PoE support for review. It is based on Espressif ESP32-D0WDR2-V3 and Silicon Labs EFR32MG24 SoCs, and can serve as both a Zigbee coordinator and Thread Border Router, with connectivity options including Ethernet, Wi-Fi, and USB. The dongle is specifically designed for popular smart home platforms like Home Assistant, Zigbee2MQTT, ioBroker, and OpenHAB. Key advantages of the Dongle Max over the recently reviewed Dongle Plus MG24 include built-in Wi-Fi and Ethernet support (in addition to USB), Power over Ethernet (PoE), and a convenient Web Console for easier device configuration. It basically provides more flexibility thanks to a wider range of connection options, and it’s easier to place it in strategic locations since it doesn’t need to be connected directly to your Home Assistant server. In this review, we’ll go through the unboxing, initial setup, […]

FOSDEM 2026 schedule – Embedded, RISC-V, Robotics, Rust, Open Hardware, and more

FOSDEM 2026 will take place on January 31-February 1, with thousands of developers meeting in Brussels to discuss open-source software & hardware projects. The free-to-attend “Free and Open Source Software Developers’ European Meeting” gets more traction every year, and in 2026, there will be at least 1,113 speakers, 1,016 events, 70 tracks, and potentially close to 10,000 attendees. As usual, I’ll create a virtual schedule with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms, including “RISC-V”, “Robotics and simulation”, and “FOSS on Mobile”, among others. I’m aware some of the talks overlap by a couple of minutes or so… FOSDEM 2026 Day 1 – Saturday, January 31 10:40 – 11:15 – RISC-V Vector optimisations in FFmpeg by Rémi Denis-Courmont FFmpeg is the most versatile multimedia codec and format support library, and was […]

EnviroGo ESP32-S3 wearable environmental monitor features 7 sensors (Crowdfunding)

EnviroGo s 7 in 1 ESP32 wearable environmental monitor

EnviroGo is an ESP32-S3-based wearable environmental monitor that tracks Organic Compounds (VOCs), UV index, temperature, humidity, air pressure, light, and motion via a 9-axis MEMS sensor. It is designed for indoor and outdoor use, and can be worn, clipped to a bag, or magnetically mounted, making it suitable for homes, offices, travel, labs, and daily use where real-time environmental data is needed. EnviroGo supports built-in Wi-Fi and Bluetooth connectivity through the ESP32-S3 WiSoC, features a small 0.96-inch IPS display, a microSD card slot for local data logging, and an RTC for time-stamped records. The device samples data at configurable intervals, uses RGB LEDs and a buzzer for visual and audible alerts, and can process data locally with AI-based prediction to spot trends such as rising VOC levels or humidity changes (with a stated 7-day learning period). EnviroGo is designed for IoT developers, researchers, smart home users, and health-conscious individuals who […]

Getting started with SONOFF Dongle Plus MG24 Zigbee adapter using Home Assistant

SONOFF Dongle Plus MG24 review AirGuard TH MINI-ZB2GS-L

We have received a sample of the SONOFF Dongle Plus MG24 (also known as Dongle-PMG24) Zigbee/Thread USB dongle for review. As its name implies, it’s based on a Silicon Labs EFR32MG24 wireless chip, and the company claims up to 200 meters range thanks to an included 3dBi antenna. It is compatible with Windows, Linux, macOS, Raspberry Pi OS, and other operating systems that support USB serial drivers. The dongle works seamlessly with popular open-source platforms, such as Home Assistant, Zigbee2MQTT, ioBroker, and OpenHAB. In this review, we will go through an unboxing of the SONOFF Dongle Plus MG24, before connecting it to a Raspberry Pi 4 running Home Assistant. We will use two Zigbee devices from SONOFF: the AirGuard TH (SNZB-02DR2) temperature and humidity sensor with an LCD, and the MINI DUO-L (MINI-ZB2GS-L) dual-channel/2-gang Zigbee 3.0 switch to demonstrate how to use the dongle with Home Assistant. SONOFF Dongle Plus […]

Tablet-like, ESP32-P4-based 7, 8, and 10.1-inch HMI displays integrate Wi-Fi 6 connectivity, 5MP camera

Waveshare has recently released the ESP32-P4-WIFI6-Touch-LCD, a family of tablet-like, fully enclosed HMI display development boards built around the ESP32-P4 SoC. The company offers 7-inch, 8-inch, or 10.1-inch configurations, all designed for industrial HMI, smart home terminals, and edge AI applications. Since the ESP32-P4 does not include built-in wireless connectivity, Waveshare has integrated an ESP32-C6-MINI module for WiFi 6 and Bluetooth 5 (LE) support. The board also leverages the ESP32-P4’s peripherals for MIPI CSI/DSI interfaces, a 5MP camera, and various I/Os, including USB 2.0 OTG and USB-to-UART Type-C ports, an SDIO 3.0 microSD card slot, dual microphones with echo cancellation, a speaker driven by an onboard audio codec, GPIO expansion headers, and optional battery support. Waveshare ESP32-P4-WIFI6-Touch-LCD specifications: Wireless module – ESP32-P4-Core SoC – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core […]

eWeLink CUBE OS enables all SONOFF WiFi and Zigbee devices to connect to Matter

All SONOFF WiFi and Zigbee home automation devices can now work with the Matter protocol. This can be done in two ways: Software path (free of charge) – Use eWelink CUBE OS on a Raspberry Pi or other host computer to bridge SONOFF WiFi & Zigbee devices to Matter. Hardware path — Install a certified Matter gateway such as SONOFF iHost, ZBBridge-U, or NSPanel Pro, and pair your WiFi/Zigbee devices to use them with Matter. The main benefit is that you no longer need to use the eWelink app, and any SONOFF devices can now work with Matter-compatible platforms, such as Apple Home, Google Home, SmartThings, Amazon Alexa, and Home Assistant. I’ll focus on the software solution in this post. Most users will likely install eWelink CUBE OS on a Raspberry Pi 4/5 connected to a supported USB Zigbee dongle if they have Zigbee devices. SONOFF lists their own ZBDongle-MAX, […]
