SmartBug smart switch integrates neatly into in-wall sockets (Crowdfunding)

SmartBug Smart Switch

SmartBug is a smart switch based on ESP32 wireless SoC, equipped with several sensors to measure temperature, humidity, power usage, and listen to sounds. It is designed to fit neatly into most in-wall sockets found around the world. Each SmartBug relies on mesh networking to communicate with each other and extend the range, WiFi for Internet connection, and Bluetooth low energy (BLE) to control additional devices without the need for any additional hub. SmartBug’s key features: MCU – 32-bit dual-core microcontroller with WiFi, wireless mesh, Bluetooth LE Connectivity 2.4GHz WiFI 4 Wireless mesh to let SmartBug act as a signal repeater Bluetooth 4.0 and BLE to control home appliances Audio Digital microphone for voices commands, baby crying (only enable if the plugin is downloaded in the app).

ESP32-H2 Bluetooth LE & 802.15.4 RISC-V SoC shows up in ESP-IDF source code


Espressif Systems is working on yet another RISC-V chip with ESP32-H2 SoC offering Bluetooth LE and 802.15.4 connectivity showing up in the ESP-IDF framework source code. A code comparison shows ESP32-H2 is very similar to ESP32-C3 with a single RISC-V core, albeit clocked at up to 96 MHz, and the first Espressif SoC without WiFi, as the WiFi radio is replaced with an 802.15.4 radio for Thread, Zigbee, etc… that can be used for the development of Home Automation, Smart Lighting, and wireless sensor network applications. While looking at the source code differences between ESP32-C3 and ESP32-H2, the really only major differences were the 802.15.4 radio and lower maximum frequency, and at the current time, it looks like most of the rest is unchanged, so it’s possible they kept the same amount of RAM (400KB), storage, and most of the same peripherals, but it could just well be the code […]

Sonoff & Tuya smart plugs found to transmit unencrypted passwords

Sonoff Tuya security vulnerability

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 […]
