HAUI 3Gang Touch Display is a 7-inch wall-mount Home Assistant dashboard with MQTT support

HAUI 3Gang 7-inch Display Wall Mount Dashboard WiFi

The HAUI 3Gang Touch Display is a wall-mount smart home control dashboard designed specifically to run Home Assistant, OpenHAB, Domoticz, or any other web-based home automation dashboard. Built around a Raspberry Pi 3B+ since it’s one of the cheapest options following Pi 4/5 price hikes, the HAUI (Home Assistant User Interface) replaces standard wall switches and fits into a standard single-gang electrical box, while its front panel spans roughly a three-gang footprint, hence the “3Gang” name. It runs a customized version of FullpageOS Linux distribution with a Chromium browser in kiosk mode and includes built-in MQTT integration along with SSH access for advanced users. HAUI Touch Display specifications Main Controller – Raspberry Pi 3B+ Display – 7-inch capacitive touchscreen Connectivity – Wi-Fi on Raspberry Pi (configured via initial setup wizard) Power Input Voltage – 120 VAC ±10% Maximum Current – 1 A Internal USB charger module (Line/Neutral wiring, no ground […]

Arduino Matter Discovery Bundle educational kit combines Arduino Nano Matter with three Modulino modules

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help users learn, prototype, and build Matter-over-Thread smart home devices quickly. The kit is based on the Arduino Nano Matter development board and works with the Matter ecosystem, including compatible platforms such as Apple HomeKit, Google Home, Amazon Alexa, and Home Assistant. The bundle also includes a Nano Connector Carrier with Grove and Qwiic interfaces, a microSD slot, and various IO options. The kit features three Qwiic-based Modulino nodes, namely a Latch Relay, a Distance module for presence detection, and a Thermo module for temperature and humidity sensing. Arduino Matter Discovery Bundle specifications: Main board – Arduino Nano Matter MCU – SiLabs MGM240SD22VNA MCU core – 32-bit Arm Cortex-M33 with DSP (digital signal processing) instruction and FPU (floating-point unit) @ 78 MHz Storage/Memory – 1536 KB flash program memory, 256 KB RAM data memory […]

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 […]

Home Assistant-compatible Makerfabs ESP32-S3-based energy meter features BL0942 energy metering IC

The Energy Meter for Home Assistant is an ESP32-S3-based single-phase energy monitoring and control module designed to work with Home Assistant via ESPHome. It measures real-time power and energy consumption and also has a remote on/off control. The device is built around the BL0942 calibration-free energy metering IC, which supports voltage, current, power, and energy measurements with less than 1% error. It operates directly from AC 100–240V, includes an onboard 15A relay for switching loads, and provides electrical isolation for safety. Connectivity is done through USB and Wi-Fi using ESPHome for easy firmware flashing, API encryption, and automatic discovery in Home Assistant. These features make it suitable for smart homes, DIY energy monitoring, smart sockets, home energy dashboards, and automation projects. Energy Meter for Home Assistant specifications: Core module – Espressif Systems ESP32-S3-WROOM-1 SoC – ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads […]

NetCube Systems Nagami Allwinner T113-S3 mini PCIe SoM features ESP32 wireless SoC, supports mainline Linux

Netcube Systems Allwinner T113-S3 SoM mainline Linux

NetCube Systems Nagami is a small Allwinner T113-S3 system-on-module that I just saw added to Linux 6.18. Besides mainline Linux support, the Allwinner SoM offers somewhat unique or unusual features that include a mini PCIe form factor and an ESP32 co-processor for WiFi 4 and Bluetooth connectivity. The Nagami also comes with 128MB DDR3 embedded in the T113-S3, 4GB eMMC flash, a Fast Ethernet PHY, and a Qwiic connector for I2C expansion modules. All I/Os are exposed through a standard mini PCIe edge connector: audio I/Os, Ethernet, USB 2.0 OTG/host, and a range of low-speed I/Os. Nagami SoM specifications: SoC – Allwinner T113-S3 CPU – Dual-core Arm Cortex-A7 @ 1.2 GHz with 32 KB L1 I-cache + 32 KB L1 D-cache per core, and 256 KB L2 cache DSP – Single-core HiFi4 VPU – H.265/H.264 video decoding up to 1080p60 and JPEG/MJPEG video encoding up to 1080p60 Memory – 128 […]

SMHUB Nano Mg24 compact Linux-based Zigbee/Thread Smart Hub combines SG2000 RISC-V SoC with MG24 wireless MCU

SMLight’s SMHUB Nano Mg24 may look like the company’s earlier SLZB-06p Zigbee to Ethernet/WiFi/USB coordinators, but it’s a more powerful Linux-based Zigbee/Thread Smart Hub that pairs SOPHGO SG2000 RISC-V SoC with Silicon Labs MG24 multi-protocol wireless MCU. Unlike traditional Zigbee/Thread adapters that connect to a host through USB or Ethernet, the SMHUB Nano Mg24 is an all-in-one solution that runs all major automation apps directly on the device, eliminating the need for a Raspberry Pi, Mini PC, or other hardware server. SMHUB Nano Mg24 specifications: SoC – SOPHGO SG2000 CPU cores 1x C906 64-bit RISC-V core @ 1GHz or 1x Arm Cortex-A53 core @ 1GHz (selectable at boot) 1x C906 64-bit RISC-V core @ 700MHz MCU – 8051 8-bit microcontroller core @ 25 to 300 MHz with 6KB SRAM GPU – None VPU – H.265/H.264 video decoding and encoding (5M @ 30fps) ISP – 5M @ 30fps NPU – 0.5 TOPS Memory […]
