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 …

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

Project Connected Home over IP

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 mobile devices, and cloud services. A unified and standardized baseline …

Pitaya Go is an IoT development board with multi-protocol wireless connectivity

One of the challenges in starting a new IoT project is the question of what connectivity to use. Depending on the nature of a project, there are several wired and wireless connectivity options that can be used to power a project and ensure it’s a success. We have WiFi, Bluetooth, Zigbee, Zwave, LoRa, ZigFox, Thread, NB-IoT, 3G/4G, and others. You can use from anyone, but which one to use is another thing because most development board only support 1 or 2 of those. Well, with the introduction of the Pitaya Go, you don’t have to worry so much about that decision. The Pitaya Go is an IoT development platform with multiprotocol wireless connectivity built-in. The Pitaya Go is based on the Nordic’s high-end multiprotocol SoC nRF52840 and the Microchip’s extremely low power Wi-Fi network controller ATWINC1500B. The nRF52840 SoC is the most advanced member of the nRF52 Series SoC family, and it is fully multiprotocol capable with full protocol concurrency.
