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

Sonoff 4CHR3 & 4CHPROR3

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.

Sonoff ZBBridge

Since the end of last year, ITEAD has introduced several Zigbee Sonoff products such as Sonoff Basic R3 Zigbee, but so far customers had to rely on third-party hardware for the gateway, and they very recently launched a CC2531 Zigbee USB dongle to ease the task.

ITEAD CC2531 Zigbee USB Dongle

Some of ITEAD Studio’s Sonoff home automation devices include Zigbee connectivity with for instance Sonoff BASICZBR3 smart switch or a version of Sonoff S31 smart socket with integrated Zigbee. Those devices usually work via a Zigbee enabled gateway that could be a router, Raspberry Pi SBC, or mini PC, which ITEAD did not offer so far. But to help people making their own Zigbee gateway the company is now selling a low-cost ($3.99) CC2531 USB dongle preloaded with CC2531ZNP-Prod firmware (Zigbee coordinator firmware), and compatible with Zigbee2MQTT open-source Zigbee to MQTT bridge once plugged into a PC, Raspberry Pi, or another Linux SBC.

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 […]
