Sonoff MINI & R3 Smart Switches Support a DIY REST API

Sonoff MINI

ITEAD Studio’s Sonoff are low-cost wireless switches based on ESP8622/ESP8285 WiSoC, and supporting WiFi and/or 433 MHz connectivity. They usually come with a firmware that allows users to control them with eWelink app for Android or iOS. But many people will install alternative open source firmware such as Sonoff-Tasmota or ESPurna to get more flexibility such as the ability to use MQTT. But the company’s latest models, including Sonoff MINI and R3 series, implement a “DIY” REST API that allows you to control the device, or flash the firmware over a LAN connection. Sonoff MINI two-way Smart Switch Sonoff MINI is designed to be installed behind existing wall-mounted light-switches and wall-mounted power-sockets. Specifications: Terminal blocks with 6x inputs/outputs: N/L Inputs –  AC 100-240V 50/60Hz 10A Max N/L Outputs – AC 100-240V 50/60Hz 10A Max S1/S2 – Designed to optionally connect a standard on/off switch Connectivity – Wi-Fi 4 – 802.11 […]

Sonoff S26 Smart Socket Mini Review & Teardown

Sonoff S26 Fan Control

ITEAD Studio very recently launched their Sonoff S26 WiFi Smart plug as a more compact and cost effective upgrade to their Sonoff S20 smart sockets, and which comes in 6 different versions for China, Australia, the United Kingdom, the United States, Europe type F for Germany, Austria, the Netherlands, Sweden, Finland, Norway, Portugal, Spain and Eastern Europe, and  Europe type E for France, Belgium, Poland, Slovakia, the Czech Republic, Tunisia and Morocco. You can find the one that suits you most on World Standard website. I was interested in getting the device, mostly to check the hardware design, so the company sent me one sample to try out. Sonoff S26 Unboxing Sonoff S26 comes is a white package with Sonoff branding. I received the US type plug (S26B model) which includes a ground pin on both side, so it’s not suitable for most sockets here in Thailand that do not […]

ESP8266 based ANAVI Light Controller can be Programmed with Home Assistant or the Arduino IDE (Crowdfunding)

ANAVI Technology previously launched a Light pHAT allowing for RGB Light strip connection to Raspberry Pi boards, and during my review of ANAVI Light pHAT with Raspberry Pi 2, it did the job, but if that’s all you want to do, the  Raspberry Pi board is clearly oversized & overpowered for the job. So Leon ANAVI got back to the drawing board and designed a similar open source hardware board – called ANAVI Light Controller – with an built-in ESP8266 module that removes the need for a fully fledged Linux board. ANAVI Light Controller specifications: Wireless Module – ESP8266MOD module based on ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Expansion Terminal block for 12 V RGB LED strip 3x I2C headers for sensors Debugging – UART header Misc – Button Power Supply – 12 V via power barrel jack Dimensions – 75 mm x 40 mm Certification […]

Android Things is Finally Getting into Products: Smart Speakers, Smart Displays, and More

Android Things was first introduced as Brillo in October 2015, before being renamed to Android Things the following year when a developer preview was released with support for Raspberry Pi 3, as well as Intel and NXP development boards. But if you can’t remember the last time you’ve purchased a device running Android Things that’s normal, because so far, there was none. Google announced this is going to change as the first set of Android Things products have been announced at CES 2018. The first category of devices to run Android Things will be Google Assistant enabled smart speakers with the launch of products such as iHome iGV1 and LG ThinQ WK7.  ODM partners have also created full speaker reference designs based on certified Android Things and Cast System-on-Modules (SoMs) powered by Rockchip RK3229, Mediatek MT8516, or based on Qualcomm SD212 Home Hub Platform. NXP i.MX 8M solutions are also […]

Acme CM3-Home is a Raspberry Pi 3 Compatible Board Designed for Home Automation

Raspberry Pi CM3 & CM3L modules are used in so many devices it’s hard to keep up. From NEC digital signage displays, to industrial touch panels, and IoT gateways, the Broadcom BCM2837 based system-on-module are found in more and more products and solutions, and number of announcements seems to have increased over the last few months. The latest product to leverage Raspberry Pi CM3L SoM is made by Italy based Acme Systems, and designed for home automation. CM3-HOME comes with opt0-isolated inputs compatible with KNX and DALI buses, various connectivity options (Ethernet, WiFi, Bluetooth, 868MHz ISM radio…), and other expansion port. Two edition of the boards are available: LITE and FULL, with the former suitable for most home automation project, and the latter adding support for some commercial lighting systems and energy harvesting Radio ISM nodes. Acme CM3-Home specifications: 200-pin SODIMM Module Slot compatible with Raspberry Pi CM3 / CM3L […]

Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it. That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case: Ingress Protection Rating – IP66 Material – PC V0 Dimensions – 132.2 x 68.7 x 50.1mm (See details) Weight – 145.0g IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 […]

$23 Sonoff 4CH Pro 4-Channels WiFi & RF Switch Ships in a DIN Rail Enclosure

ITEAD Studio’s Sonoff family is a collection of really useful and inexpensive home automation devices which have been featured multiple times on CNX Software with either to stock firmware and eWelink app, or open source firmware developed by the community. I’m using a Sonoff TH16 to control a water pump, a Sonoff Pow to monitor my office’s power consumption, and Karl used some Sonoff switches to control his lights at home. The company has now launched Sonoff 4CH Pro with 4 relays that can be controlled with buttons on the unit, WiFi, or RF remote controls, and comes in a DIN Rail enclosure.
