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, […]

Ridiculously tiny ESP32-C3 board features USB-C, one LED, and a ceramic antenna

PegorK’s f32 might be the world’s smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C connector. A board of this size will have limited features, and besides the ESP32-C3FH4 RISC-V WiFi and Bluetooth microcontroller, it comes with a USB-C port, a ceramic antenna, and a single GPIO pin connected to an LED. f32 specifications: SoC – Espressif Systems ESP32-C3FH4 Single-core 32-bit RISC-V microcontroller @ up to 160 MHz Memory – 400 KB SRAM Storage – 4MB flash Wireless 2.4 GHz Wi-Fi 4 & Bluetooth 5.0 USB – 1x USB Type-C port for power and programming Misc Tiny LED connected to GPIO10 Ceramic antenna Crystal Power Supply – 5V via USB-C port; 3.3V LDO Dimensions – 9.85 x 8.45 mm (the height must be around 4-5 mm) The PCB was designed using DipTrace and manufactured with a board thickness […]

Review of SONOFF’s latest Matter Smart Switches – Basic Gen5 and Tx Gen2

Today, we’re about to review not one, but two new Matter devices: the SONOFF Basic Gen5 Smart Switch and the SONOFF Tx Gen2 Smart Wall Switch. Both are upgraded versions of their previous models, now adding support for the Matter protocol (over Wi-Fi). The Basic Gen5 is the fifth generation of the popular Basic series, known for being affordable and widely used in the market. It’s a Wi-Fi smart switch that can control all kinds of devices, such as lights or small electrical devices. Basically, anything within its 10A limit. What’s new compared to the previous BasicR4 is the addition of Matter and near-field control via Bluetooth. As for the Tx Gen2 (T6), it’s an upgraded version of the older T2/T3 lineup. Besides adding Matter, it also brings a few new features, like adjustable backlight brightness and the Detach Relay mode. Both models support voice control via Apple Siri, Google […]
