Yeelight Smart LED Bulb M2 (Multicolor) Supports Google Home Seamless Setup

At the beginning of the year, I reviewed Yeelight Smart LED Bulb 1S with both the Yeelink Android app and Google Home app. The light bulb was one of the first to implement support for Google Home Local SDK which makes controlling the light bulb much faster but requires a Google Home compatible hardware platform such as Google Home Mini smart speaker. Using the light with Google Home app still required a Xiaomi account and go through some hoops, and that’s why Yeelight has now launched the Smart LED Bulb M2 (Multicolor) with support Google Home Seamless Setup. The Yeelight app is not needed anymore, and setup is easier with Google Home. All you need is a Google Assistant-enabled device like a Google Nest Mini or Google Nest Hub. Yeelight Smart LED Bulb M2 specifications: Bulb Interface – E26/E27 bulb Wattage – 8W Brightness – Up to 1000 lumens (equivalent […]

Shelly Motion sensor to feature Silicon Labs WiFi chip with Bluetooth-like power consumption

[Update: The information from Shelly about a new “Cortana M3” processor is incorrect, we’ve been contacted by Silicon Labs, and there’s no Cortana M3 microcontroller from the company, Shelly is just using one of the company’s Cortex-M3 based WiFi solutions (SoC or module). The article remains unchanged] WiFi is one of the most convenient ways to connect IoT devices as it’s omnipresent, low-cost, and the range is ideal for the typical smart home. That’s all good until you start to power the device with a tiny battery, as WiFi consumes much more power than Zigbee, Z-Wave, or Bluetooth. Over five years ago, Rockchip RKi6000 WiFi SoC promised Bluetooth 4.0 LE power consumption numbers allowing coin-cell powered WiFi devices, and there were some demos the following year, but I’ve yet to see a consumer device based on the solution. This brings me to the main topic of this post: Shelly Motion, […]

OPTIGA Trust-M evaluation kit for Raspberry Pi targets Connected Home over IP standard

Optiga Trust-M evaluation-kit-Raspberry-Pi-Connected Home over IP standard

Last December, we reported that Amazon, Apple, Google, and the Zigbee Alliance had partnered to create Project Connected Home over IP (CHIP) working group with the goal of developing a royalty-free, secure Smart Home standard to increase compatibility among products over WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others community protocol. Infineon has now unveiled OPTIGA Trust-M evaluation kit for Raspberry Pi designed to experiment with Connect Home over IP standard and comprised of Infineon Shield2Go HAT/adapter board, and OPTIGA Trust-M Security Shield2Go board equipped with Infineon OPTIGA Trust-M “Common Criteria Certified EAL6+” security controller. The Shield2Go adapter just re-routes the 40-pin Raspberry Pi header I/Os to sockets compatible with Infineon boards and a prototyping area. So the most important part is OPTIGA Trust-M Shield2Go which supports the following: X.509 certificates Device authentication Cryptographic support ECC NIST curves up to P-521, Brainpool r1 curve up to 512 RSA up to […]

Oplà IoT Kit is Arduino’s first open programmable IoT platform

Arduino is well-known for its maker boards and shields that are sometimes sold as part of kits to experiment with electronics. Arduino Oplà IoT kit is a little different as it looks more like an actual consumer product once assembled. Powered by an Arduino MKR WiFi 1010 board, it is designed to make getting started with IoT easy for beginners, while still allowing more advanced users to customize and hack their smart home applications. Arduino Oplà IoT Kit is comprised of several hardware components: MKR IoT carrier with a 1.2-inch OLED color display, onboard environmental sensors (temperature, humidity, pressure, light, and proximity), IMU sensor, Grove connectors, two 24V relays, and five capacitive touch buttons. Arduino MKR WiFi 1010 board powered by Microchip SAMD21 Cortex-M0+ MCU and equipped with a 2.4 GHz WiFi 4 and Bluetooth 4.2 module based on ESP32 chip. Sensors – PIR motion sensor and moisture sensor A […]

UL-Certified TP-Link Kasa Smart Plug with Dual Outlet Sells for $19.99 (Promo)

WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna. The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety. Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 […]

3µA/MHz Ambiq Apollo 4 MCU Targets Battery-powered IoT Devices with Voice Processing

Ambiq Micro is using sub-threshold voltages under 0.5V to offer ultra-low-power Arm microcontrollers. In 2015, the company launch the Apollo Cortex-M4F MCU with 30µA/MHz power consumption in active mode, which was followed in 2016 by Apollo 2 in consuming just 10µA/MHz, and Apollo 3 (Blue) dropped power consumption to as low as 6µA/MHz against using a Cortex-M4F @ 48 MHz in active mode. The fourth generation of ultra-low-power Apollo microcontroller has now been announced with Apollo 4 and Apollo 4 Blue microcontrollers – the latter adding Bluetooth – halving the power consumption of Apollo 3 at just 3µA/MHz, or ten times less than the original ultra-low-power MCU from the company. Apollo 4 (Blue) specifications and key features: MCU Core – Arm Cortex-M4F core up to 192 MHz (TurboSPOT) with FPU, Memory Protection Unit (MPU), and Secure Boot GPU – 2D/2.5D graphics accelerator with full alpha blending, texture and frame buffer […]
