Airlytix ES1 environment monitor runs ESPHome for Home Assistant integration

Airlytix ES1 temperature, humidity, light, and and noise monitoring system

Airlytix ES1 environment monitor is an ESP32-based environment tracking device that runs ESPHome. The device tracks various environmental parameters like temperature, humidity, air quality (PM1.0, PM2.5, PM4, PM10, VOCs, NOx, CO2), barometric pressure, ambient light, and noise levels. To make things even more interesting, the device ships with a compact 3D printed case and can be integrated with Home Assistant for smart home automation.

Matter 1.3 specification adds support for water and energy management, electric vehicle chargers, and various household appliances

Matter 1.3 Specification

The Connectivity Standard Alliance (CSA) has just announced the release of the Matter 1.3 specification and SDK with energy reporting, support for water and energy management devices, electric vehicle chargers, several new “major appliances”, namely various kitchen appliances and laundry dryers, and various other features. As a reminder the Matter protocol was initially introduced several years ago under the name Project CHIP to improve the interoperability of Smart Home devices from various vendors, so for example, users could connect a Matter-compatible Philips Hue light bulb to a Samsung gateway, or a white-brand Matter sensor with Google Home, etc… Matter started to pick last year with several products launched, and Paisit notably reviewed the MINI Extreme Wi-Fi Smart Switch (MINIR4M), the first Matter device from SONOFF, last October. Matter 1.3 adds various new capabilities and devices. Matter 1.3 highlights: Support for Water and Energy Management Devices Energy Management – Matter 1.3 […]

FLIP_C3 ESP32-C3 board takes up to 60V DC input, ships with ESPHome firmware

flip c3 board front

Voidbox FLIP_C3 is an open-source hardware board powered by an ESP32-C3 WiFi & BLE microcontroller that takes up to 60V DC power input feeding a 5V/2A DC-DC step-down converter and flashed with ESPHome firmware by default for Home Assistant support. The board incorporates a push-in spring release connector which means stranded (ferrules or tinning are suggested) and solid wires can be used in deploying the device in off-grid/battery-powered systems with up to 16s LiFePO4 delivering 48V through the 6-60V input port on the ESP32-C3 board. The onboard WS2812B LED can be used as a null pixel/level shifter for longer strings of addressable pixels. The ESP32-C3 – due to its support for Wi-Fi and BLE connectivity – is a popular SoC for IoT solutions and powers home and industrial automation devices such as NanoCell v2.1, Spark Analyzer, LOLIN C3 Pico, and the LILYGO T-RSC3. It is built for home automation applications […]

Enabling Zigbee in Bluetooth LE temperature and humidity monitors from Xiaomi and Qingping using Telink TLSR8258 WiSoC

XIaomi temperature humidity monitors Zigbee

Qingping CGDK2 and Xiaomi LYWSD03MMC Bluetooth LE (BLE) temperature and humidity monitors based on Telink TLSR8258 can be switched to Zigbee thanks to a custom firmware flashed over-the-air. Telink TLS8258 is a multi-protocol wireless microcontroller supporting Bluetooth LE 5, Bluetooth Mesh, Zigbee, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary and found in boards such as the LILYGO T-Zigbee and various products. Some products only enable one wireless protocol, for example, Bluetooth LE as in the just-mentioned Qingping and Xiaomi monitors, but “SmartHomeScene” has found out that it was possible to switch from BLE to Zigbee on those by simply updating the firmware. The Telink TLS8258 devices mentioned above will publish data over BLE every 10 minutes (unless humidity or temperature changes, in which case data is transmitted immediately) with the default firmware, but Zigbee can be enabled by using the pvvx custom firmware for the following models: Xiaomi LYWSD03MMC […]

Review of SONOFF SNZB-06P human presence and SNZB-04P door/window Zigbee sensors

Sonoff SNZB-04P SNZB-06P review

SONOFF has been gradually refreshing its Zigbee product lineup since August 2023, and CNX has recently written about the Temperature/Humidity Sensor (SNZB-01P), Switch/Button (SNZB-02P) and Motion Sensor (SNZB-03P), and the SONOFF SNZB-06P human presence sensor. I’ve now had the opportunity to review both the SONOFF SNZB-06P and the new Door/Window Sensor (SNZB-04P). After we keep trying them out for a few weeks, we think reliability is much improved, especially with the Door/Window Sensor, the materials made as well as the appearance look better than the previous models. As for the Human Presence Sensor, it’s the first generation, which is quite impressive considering its price and features. Let’s take a closer look. Door/Window Sensor (SNZB-04P) review Unboxing Obviously, the rounded design differs from the previous rectangular version. It integrates better with the surroundings than the previous model. Additionally, the lithium battery capacity is larger (CR2450 @550mA vs. CR2477 @1000mA), resulting in […]
