Sensirion SCD40 CO2 sensor units for makers: M5Stack UNIT CO2 and TeHyBug ESP8285 device

M5Stack UNIT CO2

We just wrote about the Infineon XENSIV PAS CO2 Shield2Go board to measure carbon dioxide (CO2) levels last week, but I’ve just come across two more hardware with a CO2 sensor designed for makers, but based on Sensirion SCD40 sensor instead, and mostly designed to monitor indoor CO2 levels since high concentrations may impact your health negatively. The first one is the M5Stack UNIT CO2 that’s designed to be connected to one of the company’s Core modules through an I2C interface, and TeHyBug portable mini sensor device equipped with ESP8285 WiFi microcontroller, as well as optional AHT10 temperature & humidity sensor and BMP280 pressure sensor, besides the SCD40 sensor. M5Stack UNIT CO2 Specifications: Sensirion SCD40 sensor CO2 Measurement range – 400 ~ 2000 ppm CO2 Sampling accuracy – ±(50 ppm + 5% of reading) Temperature range – -10 – 60°C with 0.8°C   accuracy Humidity range – 0 – 95% RH […]

Theengs open-source tools to decode BLE sensors work on ESP32, Raspberry Pi, Android phone, etc…

Theengs is a manufacturer agnostic open-source set of tools to decode BLE sensors and integrate those into smart home and IoT solutions such as Home Assistant with notably support for autodiscovery to automatically create the sensor. Theengs can be installed on various hardware from ESP32 to an Android phone or a Raspberry Pi SBC, and the solution currently supports close to forty BLE sensors from various companies including Xiaomi, Honeywell, and RuuviTag.   There are six components: The Theengs Decoder library developed in C++ for portability and translating data from sensors into human-readable data using the JSON format. The Python-based Theengs Gateway acting as a BLE to MQTT bridge for Home Assistant, OpenHAB, and NodeRED integration. It relies on the Theengs Decoder library and publishes the sensors broadcasted BLE information to an MQTT broker. The OpenMQTTGateway is also BLE to MQTT bridge, but instead of targetting Linux-capable hardware like Raspberry […]

$10 T-Zigbee board combines ESP32-C3 and TLSR8258 for Zigbee 3.0, WIFi and BLE connectivity

LilyGO T-Zigbee board combines ESP32-C3 WiFi and BLE wireless microcontroller and Telink TLSR8258 multi-protocol wireless SoC compatible with BLE 5 Mesh, Zigbee, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary standards. As I understand it, T-Zigbee is designed to act as a Zigbee to WiFi bridge, and is compatible with Zigbee2MQTT and Home Assistant, allowing easy integration into your home automation setup. Based on the hardware, I’d assume it may be usable as a BLE to MQTT gateway as well, in a fashion similar to GL.inet GL-S10 gateway, for people willing to work on the software/firmware.

Home Assistant gives new life to Insteon Smart Home products following Smartlabs bankruptcy

Smartlabs used to sell Insteon Smart Home products, but the company is now in bankruptcy proceedings, its cloud has been turned off, and users have reported their products not working since April 14. Going to Insteon website confirms the problem: …the company engaged in a sales process in November, 2021. The goal was to find a parent for the company and continue to invest in new products and the technology. The process resulted in several interested parties and a sale was expected to be realized in the March timeframe. Unfortunately, that sale did not materialize. Consequently, the company was assigned to a financial services firm in March to optimize the assets of the company. IoT and Smart Home products going offline are nothing new, either because the company is going bankrupt or the product is not profitable anymore. It happens to me with Weloop Hey 3S smartwatch which I still […]

JetHome JetHub D1 is a Linux automation controller based on Amlogic A113X SoC

I discovered JetHome Jethub D1 and Jethub H1 Linux automation controller based on respectively Amlogic A113X and S905X SoCs in Linux 5.16 changelog, as both platforms got upstreamed to mainline Linux. I had never heard of JetHome, a Russian company based in St. Petersburg, nor their products before. Both Jethub D1 & H1 will run either an Armbian-built Ubuntu operating system or Home Assistant Operating System (formerly HassOS), and support Home Assistant (Z2M), Home Assistant (ZHA), and ZIgbee2MQTT. Jethub H1 looks like a TV box with a Zigbee module, while Jethub D1 is a DIN Rail automation controller with plenty of I/Os. Let’s focus on the latter. JetHub D1 specifications: SoC – Amlogic A113x quad-core Cortex A53 processor @ up to 1.5 GHz System Memory / Storage configurations 512MB RAM and 8 GB flash 1GB RAM and 16 GB eMMC flash Connectivity 10/100M Ethernet RJ45 port Dual-band WiFi 5 and […]
