Review of the first Matter device by SONOFF – MINI Extreme Wi-Fi Smart Switch (MINIR4M)

We have just received the first Matter product from SONOFF for review, which is the Mini Extreme Switch (MINIR4M) model. Its external appearance closely resembles the Mini Extreme Switch Wifi (MINIR4) which we reviewed previously. They have different colors to distinguish between WiFi (Orange) and Matter (Green). In this review, we have experimented with various Smart Home platforms that support Matter, such as Home Assistant, Apple HomeKit, Google Home, and even their own eWeLink app. Let’s see how their operations and features differ to some extent. Quick intro for Matter. We have heard Matter/Thread together in the news. Matter is a control protocol, while Thread is a communication protocol. Both protocols can work together, or separately. Matter can operate on the top of various communication protocols, including WiFi, Ethernet, BLE, or Thread, with subtle differences such as energy efficiency, network, and resiliency. What’s crucial to note is that Matter acts […]

LILYGO T-ETH-Lite – An ESP32-S3 board with Ethernet, optional PoE support

LILYGO T-ETH-Lite ESP32-S3 is a new ESP32-S3 WiFi and Bluetooth development board with a low-profile Ethernet RJ45 connector using a WIZnet W5500 Ethernet controller, supporting PoE with an extra shield, and also equipped with a microSD card socket and expansion I/Os. ESP32-based development boards with Ethernet have been around for years including LILYGO’s own “TTGO T-Lite W5500“, but so far we haven’t many based on the more recent ESP32-S3 microcontroller except for the SB Components’ ESPi board that we covered last April. But LILYGO T-ETH-Lite ESP32-S3 adds another cost-effective board with Ethernet. LILYGO T-ETH-Lite ESP32-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps and […]

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]

SMLIGHT SLZB-06M Zigbee 3.0 PoE adapter gets Silabs EFR32MG21 microcontroller

SMLIGHT SLZB-06M is a Zigbee 3.0 to Ethernet, PoE, USB, or WiFi adapter designed to work with multi-vendor software systems such as Zigbee2MQTT and Home Assistant ZHA. This will let you integrate any supported Zigbee devices into smart home automation systems like Home Assistant, OpenHub, or HomeSeer. The SLZB-06M is a variant of the SLZB-06 Zigbee PoE adapter introduced last year with the main difference being the Zigbee chip as the new model is equipped with Silicon Labs EFR32MG21 microcontroller instead of Texas Instruments СС2652Р. An ESP32 WiFi and BLE chip is still used to work with peripherals such as the LAN8720 Ethernet chip and a CP2102N USB/UART converter chip. SMLIGHT SLZB-06M specifications: Wireless SoCs Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ 80 MHz with 352KB flash, 1024KB ROM for protocols and library functions, 96KB SRAM, integrated power amplifier, Bluetooth 5.2 Low Energy and 802.15.4 radios (Zigbee and Thread) Espressif […]

SparkFun launches ESP32-based “Arduino IoT Weather Station” with Arduino IoT Cloud integration

SparkFun’s Arduino IoT Weather Station is a complete weather station kit leveraging the company’s MicroMod ecosystem with an ESP32 Processor Board and various sensors and developed in collaboration with Arduino for integration into their IoT Cloud service. Most people will check the weather on the Internet or watch the weather forecast on TV, but if you live in a remote area with a micro-climate or just want to have fun building your own weather station, the latest SparkFun kit will allow you to monitor temperature, air and soil humidity, wind speed and direction, lightning, and rainfall data at home and monitor the data from anywhere using a web browser. Arduino IoT Weather Station kit content: MicroMod ESP32 Processor module MicroMod Weather Carrier Board with a BME280 temperature, pressure, and humidity sensor and an AS3935 lightning detector only. The optional VEML6075 UV sensor is NOT included. The Weather Meter Kit with […]

ESP ZeroCode web application creates custom Matter-certifiable firmware for ESP32 targets

Low-code/no-code platforms keep on coming and Espressif Systems ESP ZeroCode adds to the list. It is a web application designed to prepare Matter-certifiable firmware for ESP32 devices as per the user’s requirements. The website is supposed to streamline the product development where the firmware is developed for you (no need for those costly software/firmware engineers!) and future OTA updates are also guaranteed for a period of three years. It’s a bit similar to the Tuya platform, but for ESP32 devkits, modules, and/or rebranded products with Matter-certified firmware. So I went to the website to give it a try in Firefox in Ubuntu. After registration and login, we are given three options: Your products, Create a new product, and Rebrand a Certified Product I went with the second option and named by new product “CNX Software Gizmo”. In the next step, we can select the device type between socket, plug, light, […]
