Sonoff Zigbee Bridge Now Supports Tasmota Firmware, Home Assistant, Zigbee2Tasmota

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 comments section on CNX Software and other places, with the […]

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 so far. You’ll find source code on Github, and a […]

Tasmota Open Source ESP8266 Firmware Now Supports Zigbee Connectivity

Tasmota Zigbee to WiFi Gateway Prototype

Sonoff-Tasmota is a popular open-source firmware designed to run on ESP8266 hardware for home automation projects. It was initially designed to run on devices from ITEAD Studio Sonoff family but now supports more products, boards, and modules from other brands such as Shelly, Wemos, Blitzwolf, and others. So the first news is that the project has recently been renamed from Sonoff-Tasmota to just Tasmota, and documentation has been moved from Github Wiki to Github.io. Tasmota Zigbee Support A piece of more important news is that Tasmota now supports Zigbee. More specifically, the Z2T (Zigbee to Tasmota) concept allows you to make your own Zigbee to WiFi bridge by combining Z-Stack-firmware on CC2530 and Tasmota firmware on ESP8266 / ESP82xx hardware. Basically all you need is ESP82xx hardware connected to a Texas Instruments C2530 based Zigbee device over a serial. Note that C2531 based device won’t work since they are connected over USB. Normally, C2530 firmware is flashed through CC Debugger […]
