Sonoff & Tuya smart plugs found to transmit unencrypted passwords

There are many low-cost smart plugs based on ESP8266 that provide a convenient way to control lights or home appliances with your smartphone. But cybersecurity firm A&O IT Group found vulnerabilities in ITEAD’s Sonoff S26 and Ener-J Wi-fi (Tuya) smart plugs that would allow an attacker to easily access your wireless network. The first security vulnerability is pretty common and hard to exploit since it’s only a concern during the setup. Sonoff S26 starts itself into access point mode with ITEAD-1001xxxxxx SSID, and is set up through the eWelink app with the user not needing to know the password. But with older firmware is was needed, so ITEAD still shares the default password: 12345678 in the user manual, and it can be used to connect to the smart plug by anyone. But once configured, it’s not accessible anymore as the smart plug should be in client mode connected to your […]

$7 ITEAD Zigbee 3.0 USB dongle features Silicon Labs EFR32MG21 MCU

ITEAD is known for its Sonoff home automation products that started with ESP8266 WiFi and/or RF connectivity several years ago, but more recently the company started to offer Zigbee compliant products including Sonoff BASICZBR3 smart switch, Sonoff ZBBridge WiFi to Zigbee Gateway, or a cheap $4 CC2531 Zigbee USB Dongle compatible with Zigbee2MQTT open-source firmware. The company has now launched a more powered Zigbee 3.0 USB dongle, yet still affordable at $6.99, based on the same Silicon Labs EFR32MG21 wireless MCU as used in the Sonoff ZBBridge with a faster core, more RAM, and a more powerful radio. Key features and specifications: Wireless MCU – Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ up to 80 MHz with DSP and FPU, up to 1024 kB flash, up to 96 kB RAM, 2.4 GHz IEEE 802.15.4 for Zigbee or Thread Host interface – USB port Expansion – 7-pin IO header with programming […]

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 […]

Sonoff SNZB Zigbee Sensors and Switches Launched for under $10

ITEAD had started to expand from WiFi and RF433 capable Sonoff home automation devices into Zigbee smart home solutions in recent months with the launch of products such as Sonoff ZBBridge WiFi to Zigbee gateway and a TI CC2531 based Zigbee USB dongle preloaded with firmware compatible with Zigbee2MQTT. But so far, they had only one Zigbee node, namely Sonoff BASICZBR3 Zigbee power switch. More options are now available with the launch of four Sonoff SNZB Zigbee sensors and switches working with the company’s ZBBridge. Key features of the four new Zigbee sensors & switches: SNZB-01 Zigbee wireless switch Touch button with single, double press and long press support Battery – 3V (CR2450) Dimension – 43x43x16mm SNZB-02 Zigbee temperature & humidity sensor Unnamed temperature and humidity sensor Battery – 3V (CR2450) Dimension – 43x43x14mm SNZB-03 Zigbee motion sensor Built-in PIR sensor with 6m range and 110°viewing angle. Battery – 3V […]

Zigbee Firmware News – TI Z-Stack 3.0 Zigbee for CC2530 & ptvo Zigbee FW Configuration Tool

We’ve been writing about Zigbee more in recent months with either product announcements such as Sonoff ZBBridge WiFi to Zigbee gateway, and open-source software updates such as Tasmota support for Zigbee connectivity. We’ve recently been tipped about Zigbee-related news, namely TI Z-Stack 3.0 Zigbee router firmware port to Sonoff BASICZBR3, and ptvo Zigbee Configurable Firmware v2.4 GUI tool designed to create alternative Zigbee switch and router firmware for TI CC253x based modules and devices TI Z-Stack 3.0 Zigbee Router Firmware on Sonoff BASICZBR3 Kirovilya, a well-known open-source developer and founder of ioBroker open-source home automation software, has ported TI Z-Stack 3.0 Zigbee router firmware to CC2530 and tested it on Sonoff BASICZBR3 with DS18B20 waterproof temperature sensor. This is significant as Sonoff BASICZBR3 is only shipped with TI Z-Stack Home 1.2 Zigbee router firmware and I was told no one else had ported TI Z-Stack 3.0 Zigbee to CC2530 chip […]

Sonoff 4CHR3 is a 4-gang Wi-Fi Smart Switch with optional RF433 Connectivity

ITEAD Studio introduced Sonoff 4CH 4-gang WiFi + RF switch in 2017 with a DIN rail enclosure, compatible with eWelink Android/iOS app, and offering three modes of operations selectable from physical switches on the unit: Self-locking mode – Each relay can be turn on and off independently. Interlock mode – Only one of the relay can be turned on at a given time. For example if R1 is on, and your press R2 to turn it on, R1 will automatically turn off Inching mode – A button press on the unit, mobile app, or RF/WiFi remote control will turn on the relay for X seconds as defined by K6 “delay” switch within a 0.5 to 3600 seconds range. The company has now launched the similar SONOFF 4CHR3 4-gang WiFi switch and 4CHPROR3 model that adds 433MHz connectivity, with the main difference again the previous generation being the ability to select […]
