When I wrote about the Home Assistant 2025.3 release last week, it was pointed out to me that ESPHome firmware had its own release on February 19th, and in other Smart Home news, Home Assistant got Matter certified, and some ChromeCast devices temporarily stopped working which impacted video/audio streaming and integration with Google Home. Let’s have a quick look at all three pieces of news. ESPHome 2025.2.0 firmware ESPHome 2025.2.0 was released on February 19 implements audio components improvements with support for new components/hardware for better support of Espressif’s S3-Box products, new speaker components for advanced functionality when using Voice Assistant, a new speaker media player component for announcements and music streams, and a mixer speaker component to combine the two streams. The new release also supports alpha-blending images when using LVGL, and the Online Image Component was updated to add support for both BMP and JPEG image formats. It […]
ESP32-S3 based AC voltage controller/dimmer features a knob with integrated display
Makerfabs has recently introduced Matouch 1.28-inch ToolSet_AC Dimmer an open-source ESP32-based AC voltage controller for dimming lights or adjusting motor speeds using phase-cut dimming. Built around an ESP32-S3 wireless MCU, it features a 1.28” capacitive touch display (240×240), and a UI designed with LVGL/Squareline and the Arduino V2.3.4 IDE. The device relies on a BT139 Triac and a zero-cross detection circuit for precise AC voltage control, along with an onboard relay to enable a full AC on/off switch. With an integrated AC-DC module providing 5V @ 0.6A, it can operate within an input range of AC 100-240V, 50Hz-60Hz, with a maximum load of 10A at 240VAC. Designed for home and industrial applications, it can control lighting environments and electrical appliances while being open-source for customization and integration into various automation projects. Matouch 1.28-inch ToolSet_AC Dimmer specifications: SoC – Espressif Systems ESP32-S3 CPU – Xtensa® Dual-core 32-bit LX7 Microprocessor with up to 240MHz […]
Home Assistant 2025.3 released with dashboard view headers, tile card improvements, better SmartThings integration
The popular Home Assistant has gotten an update with version 2025.3 that brings dashboard view headers, several tile card improvements, better map clustering, streamed responses from LLMs, and improved SmartThings integrations. Let’s have a look at some of the improvements starting with dashboard view headers which allow users to add a title and welcoming text to dashboards using Markdown and templates. You can also add badges next to the headers. Home Assistant 2025.3 also brings plenty of improvements to tile cards: Adding a circular background around tiles that perform actions, and leaving the ones that just show extra information without a circle Features of a tile card can now be positioned inline in the tile card (e.g. on/off button) New features: switch toggle, counter toggle (to increase, decrease, or reset a counter entity), animations when hovering over atile card Editor improvements for ease of use The new version of Home […]
STMicro STM32WBA6 2.4 GHz wireless MCU gets up to 2MB flash, 512KB SRAM, USB OTG, and more
STMicro had two announcements yesterday. I’ve already covered the launch of the ultra-low-power STM32U3 microcontroller family, so today, I’ll check the new 100 MHz STM32WBA6 Cortex-M33 wireless MCU family with 2.4GHz radios for Bluetooth LE 6.0, Zigbee, Thread, and Matter designed for wearables, smart home devices, remote weather sensors, and more. The STM32WBA6 is an evolution of the STM32WBA family introduced last year, especially of the STM32WBA54 and STM32WBA55 with many of the same features SESIP (Security Evaluation Standard for IoT Platforms) Level 3 security certification, but gets more memory and flash with up to 512KB of SRAM and up to 2MB of flash. The new STM32WBA6 family also gains a High-Speed USB OTG interface and extra digital interfaces such as three SPI ports, four I2C ports, three USARTs, and one LPUART. STMicro STM32WBA6 key features and specifications: MCU core – Arm Cortex-M33 at 100MHz with FPU and DSP Memory […]
ESP32-C6-based Wi-Fi relay board features six 10A relays, supports Home Assistant, 3D printed enclosure
Seeed Studio’s XIAO 6-Channel Wi-Fi 5V DC Relay is a compact ESP32-C6 Wi-Fi relay board built around the XIAO ESP32C6 module which supports Wi-Fi 6, BLE 5.0, Zigbee, and Thread connectivity.

The OpenVoiceOS Foundation aims to enable open-source privacy and customization for voice assistants
The OpenVoiceOS Foundation, or OVOS Foundation for shorts, is a non-profit organization dedicated to advancing open-source voice assistant technology and offers an open-source privacy-focus alternative to voice assistant by large companies like Amazon, Google, and Apple. One of the founders, Peter Steenbergen (j1nx), explained to us it all started when he read an article on CNX Software about Mycroft Mark II voice assistant hardware in 2018. He ended up being involved and created “MycroftOS“, later renamed to “OpenVoiceOS – Mycroft Edition”, as a Just Enough OS utilizing Buildroot and working on the Mark II. There were some tensions with the open-source community at some point, and the Mycroft project went south from there and the company had to close in 2023. Eventually, OpenVoiceOS took over the codebase of Mycroft A.I. and managed to merge lingering PR from the open-source community. Together with NEON A.I., they took over the Mycroft A.I. community […]
Xcrhom T4S WiFi outdoor smart socket features power meter function, Tasmota open-source firmware
ESPHome is the favorite open-source firmware of Smart Home devices, but Tasmota is another option that’s been available for many years. We’ve just seen fewer products based on Tasmota (previously Sonoff-Tasmota) in recent years, but it recently showed up on a credit card-sized quad relay board, and I’ve just come across Maker Go’s Xcrhom T4S WiFi Outdoor Smart Socket that also ships with Tasmota firmware and sells on AliExpress for $24.88 shipped. The Xcrhom T4S exposes two sockets with dust and rainproof covers to be used safely outdoors, integrates a power meter, and the Tasmota firmware enables MQTT support, Home Assistant compatibility, and support for Amazon Alexa and Google Assistant.
