ESPurna ESP8266 Automation Firmware Gets Support for BME680 Sensor’s Precise Indoor Air Quality Measurements

BME680 air quality sensor

Bosch BME680 is a 4-in-1 air quality sensor measuring relative humidity, barometric pressure, ambient temperature, and gas (VOC) levels. It’s found in boards such as STM32 based Metriful Sense or Nordic Thingy:91, and Bosch Sensortec published an Arduino library based on “Bosch Sensortec Environmental Cluster (BSEC) Software” to provide precise calculations temperature, humidity, pressure, and indoor air quality (IAQ). BSEC proprietary algorithms can provide indoor air quality data as good as more expensive CO2 sensors according to a recent presentation by the company. Max Prokhorov, lead ESPurna maintainer, and Rui Marinho noticed none of the popular open-source ESP8266 automation firmware including ESPurna, Tasmota, and Esphome supported BME680 sensor just yet. So they decided to work together to add BME680 sensor support via BSEC library to ESPurna firmware, and now it’s very easy to use as you just need to define BME680_SUPPORT=1 before compiling the firmware. You’ll find the now-merged pull […]

M.2 and Half-size mPCIe Cards Support Real-Time Ethernet and FieldBus Networks

Hilscher cifX M.2 and half-size mini PCIe cards powered by the company’s NETX 90 network-on-chip multi-protocol Cortex-M4 SoC bring real-time Ethernet and FieldBus to compatible systems. The tiny cards are designed for PC-based devices such as IPC’s, HMI’s and robots, and support various firmware for PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave, or OpenModbus/TCP. The company claims its cifX M.2 (A+E key) and half-size mini PCIe cards are the smallest multiprotocol PC cards on the automation market with a size of 22×30 mm and 30×26.8 mm respectively. The cards also support extended temperature from -20°C to 70°C and offer one hardware platform for all real-time Ethernet slave protocols. Besides PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave, and OpenModbus/TCP, Hilscher will provide support for CC-Link IE Field Basic and Ethernet POWERLINK Slave in new firmware available in Q4 2020, and OPC UA and MQTT functionalities are planned for future releases. The cards are […]

Sonoff Zigbee Bridge Now Supports Tasmota Firmware, Home Assistant, Zigbee2Tasmota

Sonoff Zigbee Bridge & Tasomota Home Assistant

Sonoff ZBBridge (aka Sonoff Zigbee Bridge) WiFi to Zigbee gateway was launched a few months ago for $16.90 plus shipping, and it’s now also listed on Banggood for $17.99 shipped. It allows users to control Zigbee devices connected to the gateway using the eWelink mobile app used with other Sonoff devices. But many people like to run Tasmota firmware on their Sonoff devices since it’s open-source and provided more flexibility such as integration with Home Assitant or Domoticz. There was already support for Zigbee in Tasmota at the time but only for Texas Instruments SimpleLink CC253x Zigbee MCU’s, and Sonoff ZBBridge is made of an ESP8266 WiSoC and a Silicon Labs EFR32MG21 Gecko Series 2 Cortex-M33 Zigbee microcontroller. So I just suspected that eventually, Sonoff Zigbee Bridge could support Tasmota open-source firmware but that would take some time… It took about four months. Not too bad. It started in the […]

Aegis Secure WiFi Smart Deadbolt Works with Android/iOS Phones (Crowdfunding)

Aegis Secure WiFi Smart Lock

We previously wrote about smart lock systems that allow you to open your door with the help of your smartphone. Products covered including Xiaomi Sherlock M1 that only works with specific doors/locks, and K1 smart lock box that stores your keys in a rugged box meaning it works with all door mechanisms, but it does not seem particularly secure to me. BOSMA Aegis Bluetooth & WiFi smart deadbolt looks to potentially a more secure solution as it should work with any door, and complements your main lock which you may want to use when you are not at home for longer periods of time. Aegis smart deadbolt specifications: Connectivity – Built-in Bluetooth; WiFi via a WiFi connector shipped with Aegis Voice Assitant Integration – Google Home and Amazon Alexa Optional BOSMA Sentry smart doorbell with Storage – Up to 128GB via MicroSD card slot; cloud storage Video – 1080p video […]
