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 […]

OpenWiFi Open-Source Linux-compatible WiFi Stack Runs on FPGA Hardware

WiFi is omnipresent on most connected hardware, and when it works it’s great, but when there are issues oftentimes they can not be solved because the firmware is a closed-source binary. I understand companies do that either to protect their IP and/or make sure end-users do not break FCC compliance. OpenWiFi project aims to deliver a completely open-source SDR (Software Defined Radio) WiFi implementation compatible with Linux and running on FPGA hardware. OpenWiFi currently supported features: 802.11a/g; 802.11n MCS 0~7; 20MHz Mode tested: Ad-hoc; Station; AP DCF (CSMA/CA) low MAC layer in FPGA Configurable channel access priority parameters: duration of RTS/CTS, CTS-to-self SIFS/DIFS/xIFS/slot-time/CW/etc Time slicing based on MAC address Easy to change bandwidth and frequency: 2MHz for 802.11ah in sub-GHz 10MHz for 802.11p/vehicle in 5.9GHz The developers tested OpenWiFi on Xilinx ZC706 FPGA evaluation kit coupled Analog Devices fmcomms2/fmcomms4 RF board to form an access point, and connected it to […]

iCommSemi SV6166F is a Low-Power WiFi SoC for IoT and Embedded Systems

The other day I wrote about Sonoff Micro WiFi USB Smart adapter featuring a CKW04 WiFi chip, but one person suspected it may be based on iCommSemi SV6166F chip with very similar features and the same 6x6mm form factor. It’s still unclear whether that’s the chip used in Sonoff Micro, but AFAICR I never heard about iCommSemi previously, so let’s have a look at SV6166F in particular. The SV6166F is a low-power single-chip device designed for integration into the Internet of Thing and embedded systems with support for 802.11b/g/n WiFi at 2.4 GHz. SV6166F highlights: MCU – Andes Technology N10 processor with ILM/DLM and I-cache. Memory & Storage 128K ROM and 192 KB SRAM for Instruction and data SRAM in total 8K retention SRAM 2MB (16 Mbit) SPI flash in package Flash and PSRAM controller up to 16MB/64Mb with XIP WiFi Connectivity 802.11b, 11g, and 802.11n 1T1R AP/STA mode – […]

Sonoff Micro WiFi Smart USB Adapter Sells for $5

ITEAD Studio Sonoff family of WiFi-powered home automation devices is convenient to use with voice commands or mobile apps, and for those who want to more control over what runs in their network, Sonff devices are usually compatible with open-source firmware such as Sonoff-Tasmota. We’ve very recently written about Sonoff D1 smart dimmer switch, but the company also launched Sonoff Micro WiFi smart USB adapter that allows you to control USB powered devices. Sonoff Micro specifications: Power Input – 5V/2.5A USB type-A male Output – 5V/2.5A USB type-A female; BC 1.2 charging, max 1A output for charging Connectivity – 802.11 b/g/n WiFi 4 @ 2.4 GHz Misc – Power and WiFi LED’s, switch button Dimensions – 45 x 30.5 x 26 mm (PC V0 flame-retardant material) Weight – 17 grams Certifications – CE, FCC There’s no integrated power supply, so Sonoff Micro targets specifically USB power devices such as USB […]

$7 Sonoff D1 Smart Dimmer Switch Supports Mobile App, RF433 Remote, and Voice Assistants

Sonoff D1 Smart Dimmer Switch & RF433 Remote

ITEAD Studio Sonoff is a family of WiFi or/and 433 MHz RF connected smart home switches, sockets, light bulbs or other products for home automation. They are usually based on ESP8266 WiSoC and while the pre-loaded firmware works with eWelink Android/iOS app and popular voice assistant, it’s also possible to load open-source firmware such as Sonoff-Tasmota or ESPurna to add MQTT and other protocols in order to integrate those with home automation solution such as Domoticz, or something control those from your web browser. The company has now launched another Sonoff device, namely Sonoff D1 smart dimmer switch which – as its name implies – will allow you to dim incandescent and dimmable LED lights. Sonoff D1 smart dimmer switch specifications: Connectivity – RF433 and 802.11b/g/n WiFi 4 Max Current – 1A Max Power – 400W for Incandescent lamp, and 150W for LED light Power Supply – 110V-230V AC input […]
