Shelly H&T is a Battery Powered ESP8266 WiFi Temperature & Humidity Sensor

Battery Powered ESP8266 Temperature Humidity Sensor

WiFi and long battery life do not usually go hand-in-hand, but as we’ve seen recently, companies have managed to design battery powered WiFi cameras that are said to last up to a year on a charge. So for simpler WiFi devices it should be feasible to last over a year, and that’s what “Shelly H&T” – an ESP8266 based battery-powered WiFi temperature and humidity sensor has apparently achieved, with claims of up to 16 months battery life. Shelly H&T specifications: Connectivity – 802.11 b/g/n WiFi (Wifi 4) Sensor – Temperature & humidity  Battery – 1x CR123A battery good for up to 16 months Dimensions – 35 mm Ø sphere with flat top/bottom  The firmware supports MQTT, and a Rest API, and works with Alexa, Google Home, and home automation suites like OpenHAB, Home Assistant, or Domoticz. The sensor is “open source ready”, meaning you’ll be able to flash your own firmware through the serial interface as shown below. The device …

Azul Systems’ Zulu Embedded is a Build of OpenJDK for ARM, MIPS, PowerPC, and x86 Compliant with Java SE standard

Yesterday as I wrote about the Embedded Systems Conference 2017 schedule I came across a potentially interesting talk entitled “Building A Brain With Raspberry Pi and Zulu Embedded JVM” by Azul Systems that will explain how to build a brain emulator using a cluster of Raspberry Pi boards. I wanted to find more about it, but I have not been able to find any details about the project/demo at this stage. However, I could still learn a bit more about Zulu Embedded, which is said to be an open source Java Virtual Machine based on OpenJDK, compliant with Java SE standard, working on 32-bit & 64-bit ARM & x86, MIPS, and PowerPC, as well as  multiple operating systems. Some of the key features of Zulu Embedded include: Java Support – Java 6, 7, 8, and 9 when available Java Configurations – Headless, headful, or compact Java Compact Profiles Hardware – ARMv7 and 32-bit ARMv8, ARM64, Intel/AMD x86, 32-bit and 64-bit, …

Engimusing DIY Home Automation Modules Are Managed with openHAB installed on ODROID-C1 Board (Crowdfunding)

Engimusing has launched a crowdfunding campaign on Kickstarter for their home automation solutions comprised of tiny modules (20x20mm) based on Silicon Labs Gecko EFM32 MCUs, some sensor modules and a server based on ODROID-C1 board and enclosure pre-installed and configured with openHAB open source home automation software. There are not that many technical details about the EFM32 modules, but they come into two variants: standalone & DF11-10 I/O, the latter allowing you to vertically stack multiple modules. This video shows how DF11-10 IO connectors work. The modules are said to be programmable with the Arduino IDE. The openHAB server is a standard ODROID-C1 board (Amlogic S805, 1GB RAM) with 4GB flash (eMMC or micro SD), and a black enclosure. If you value your money more than your time, and/or already have another computer or board (Raspberry Pi, BeagleBone Black…) that runs Linux, you could also install and configure openHAB by yourself. The company is trying to raise a lowly $5,000, …
