Sonoff ZBBridge WiFi to Zigbee Gateway Launched for $16.90

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. But now the company’s just-launched Sonoff ZBBridge WiFi to Zigbee gateway allows people to control compatible Zigbee devices using eWelink mobile app. Sonoff ZBBridge specifications: Wireless Connectivity – 2.4 GHz 802.11b/g/n WiFi 4 and Zigbee 3.0 Power Input – 5V/1A Dimensions – 62 x 62 x 20 mm (PC V0) Weight – 35 grams Temperature Range – -10 to 40°C The gateway is working with BASICZBR3 Smart Switch, S31 Lite zb Smart Plug, and the upcoming SNZB-01 Wireless Switch, SNZB-02 Temperature & humidity sensor, SNZB-03 motion sensor, and SNZB-04 wireless door/window sensor. It will also work with other smart devices certified by the ZigBee […]

$4 ITEAD CC2531 Zigbee USB Dongle Works with Zigbee2MQTT Out of the Box

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. ITEAD CC2531 Zigbee USB dongle specifications: MCU – Texas Instruments CC2531F256 Zigbee and IEEE 802.15.4 wireless MCU with 8kB RAM, 256kB Flash pre-loaded with CC2531ZNP-Prod firmware for zigbee2mqtt application Host Interface – USB 2.0 male port Expansion – 8-pin unpopulated header with 8 I/Os Debugging – Debug […]

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 […]

Project Connected Home over IP (CHIP) Working Group is Backed by Google, Apple, Amazon, and the Zigbee Alliance

Amazon, Apple, Google, and Zigbee Alliance have partnered to create Project Connected Home over IP (CHIP) working group aiming to develop a royalty-free, Smart Home standard to increase compatibility among products, and with security at the forefront. The new standard will be separate from Zigbee 3.0 / Pro, and Zigbee Alliance board member companies such IKEA, Legrand, NXP Semiconductors, Resideo, Samsung SmartThings, Schneider Electric, Signify (formerly Philips Lighting), Silicon Labs, Somfy, and Wulian will also join the CHIP working group and contribute to the project. The standard specified by Project Connected Home over IP will rely on existing technology from the networking layer including TCP/UDP transport protocol, IPv6 network and various physical & media standards such as WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others. Instead, it will define what happens at the application layer level with the following points of focus: End-to-end data security and privacy among in-home and […]
