Sonoff ZBBridge gateway can be used as a Zigbee router/repeater

Sonoff ZBBridge WiFi to Zigbee gateway was introduced in April 2020, and a few months later got support for Tasmota ESP8266 firmware and Gecko firmware for either Home Assistant or Zigbee2MQTT support. But there’s now a new Tasmota firmware that converts Sonoff ZBBridge into a Zigbee router (a.k.a. Zigbee Signal Repeater or Zigbee Range Expender) following a request on Tastoma Github’s issue tracker from last year. The firmware, unofficial yet signed, was released a few days ago by xsp1989 Github’s user with a link to the firmware on Google Drive. Digiblur successfully tried it out on its own Sonoff Zigbee bridge and published the instructions. Assuming you already have Tasmota flashed to the device, switching to the router software is basically a firmware upgrade from the Tasmota web interface. Once the update is complete, you’ll still need to access the console in Tasmota in order to run a command to […]

Ai-Thinker BW16 is a dual-band WiFi & Bluetooth 5.0 IoT module (Sponsored)

Many users prefer the ESP32 when implementing WiFi & Bluetooth into their IoT projects. But Ai-Thinker BW16 offers dual-band WiFi 4 & Bluetooth 5.0 connectivity through Realtek’s RTL8720DN chipset which may provide more reliable connectivity where the 2.4 GHz band is crowded. The module integrates an Arm Cortex-M4F compatible high-performance MCU, an Arm Cortex-M0 compatible low power MCU, WiFI 802.11 a/b/g/n, MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports to control peripheral devices. BW16 module One significant difference between BW16 and ESP32 module is that it has two serial port interfaces, so attention should be paid to the wiring of the UART interfaces. The following diagram shows the two serial interfaces of the BW16 module. One of the module serial interfaces is used to send and receive AT commands to control connectivity from a host processor or microcontroller, while the other serial port is used […]

Blink an LED on ESP32 board with Tuya Link SDK

Tuya is an All-in-one IoT Platform that enables the user to build smart IoT solutions by connecting devices efficiently, securely, and reliably. This is a getting started article to set up the Tuya platform with the Espressif’s ESP32 boards via tuya link SDK. Further, we use it to control an LED through an Android device. When the switch in the Tuya Smart App is turned ON, the LED connected to the ESP32 board glows and vice versa. Prerequisites Hardware: ESP32 board LED with suitable ballast resistor Breadboard, micro-USB cable, and connecting wires Software: Tuya Account: Tuya IoT Platform (Web) Tuya Account: Tuya Smart Application (Android) Python 3.x Arduino IDE GitHub Link: https://github.com/JayeshRajam/Tuya-ledapp.git Hardware Connections for Tuya Link SDK The ESP32 board is placed on a breadboard. The positive terminal of the LED is connected to digital pin 5 of the ESP32 board and the negative terminal is connected to the […]

Review of an ESP32-based BLE to MQTT gateway – Part 1: GL.inet GL-S10 unboxing and teardown

GL.inet introduced the GL-S10 BLE to MQTT IoT gateway last month with an ESP32 module offering WiFi and Bluetooth connectivity, as well as Ethernet and PoE support. I got offered a sample for review, and just received it together with the optional BLE beacon. So today, I’ll first have a look at the content, and check out the hardware with a teardown. GL.inet GL-S10 unboxing The package shows us the main features with Bluetooth LE 4.2, WiFi, PoE, and external antenna, with GL-S10 described as a BLE IOT GATEWAY connecting IoT devices to the Cloud. The gateway ships with a getting started guide, an antenna, a USB cable for power, as well as the beacon which we can see with a 3M stick tape. On one side, we have the RJ45 connector for Ethernet and a micro USB port for power, while the other side features a reset button, plus […]

SONOFF releases HTTP API for SPM-Main power meter

SPM-Main is the main unit of Sonoff Smart Stackable Power Meter using RS485 to provide up to 128 relays. Besides support for the eWelink mobile app, we were promised an HTTP API at the time of the launch in September 2021. ITEAD kept its promises and has now released the HTTP API for the SPM-Main smart power meter to allow IoT home automation users and developers to control SONOFF devices via existing home automation open-source platform or local HTTP client. It’s the same REST API used for SONOFF MINI & R3 smart switches, but it adds support for power monitoring as well. The API allows you to switch between eWelink and DIY modes as needed, and provides the following functions: Device Status Broadcast – Returns the switch status of all channels with current, voltage, power, overload status, RS485 communication status, and more Get the List of Sub-device – List of […]

Playing with Sonoff Zigbee & WiFi automation – Part 1: Hardware overview

I don’t think I’ve ever used Zigbee, but I’ll soon have the opportunity as ITEAD sent me the Sonoff ZBBridge gateway, a Sonoff T2 2-gang WiFi switch as well as a Zigbee motion sensor. I had reviewed several Sonoff devices in the past, but it had been over three years that I hadn’t. ITEAD recently contacted me basically telling me I could select whatever I wanted from their product list for a review on CNX Software. Since I had reviewed several of the company’s WiFi smart sockets, smart switches, and a light bulb, I had less to play with, and then I thought it might be fun to play with Sonoff Zigbee products. But I did not own any Zigbee hardware, so I had to think about a use case. I have a small annoyance in the house I rent. When we come back at night, we have to leave […]
