TASMOTA Now Supports ESP32 Targets including some Ethernet and Camera Boards

Tasmota ESP32

TASMOTA open-source firmware was initially designed for ESP8266 or ESP8285 based Sonoff home automation devices providing an alternative to eWelink firmware with support for MQTT protocol allowing integration with home automation frameworks like Domoticz or openHAB. It has since then expanded to support hardware from various brands, but until recently you were still limited to products with ESP8266 or ESP8285, and ESP32 was not supported. The good news is that TASMOTA has now gotten experimental support for ESP32 boards and products such as TTGO T-Camera. You’ll find basic documentation and well as Tasmota ESP32 (aka Tasmota32) firmware files for LilyGO TTGO T-Camera board, displays, and I2C sensor on Tasmota Github.io website. The ESP32 port is based on Jörg Schüler-Maroldt’s work. PuceBacoon also found other ESP32 boards in the source code including Olimex ESP32-PoE board in xdrv_82_ethernet.ino file and “AI Thinker” cameras in xdrv_81_webcam.ino. If you’d like to give it a try you can either download Tasmota32 firmware or built it …

$5 Sinilink WiFI USB Power Switch Works with Tasmota Firmware, Supports up to 20V/5A

Sinilink WIFI USB Power Switch

Late last year, ITEAD launched Sonoff Micro WiFi USB switch that allows you to turn on and off USB powered devices over WiFi using eWelink app for Android or iOS. It integrates with Amazon Alexas and Google Home, and does the job, but people who like to use the open-source Tasmota firmware will be disappointed to learn it’s not based on ESP8266 processor hence not compatible. Luckily, there’s another option: Sinilink WiFi USB switch (aka XY-WFUSB) based on ESP8266 WiFi SoC, and supporting up to 20V/5A according to the manufacturer. It is currently sold for under $5 including shipping on Aliexpress. Sinilink XY-WFUSB specifications: WiSoC – Espressif ESP8266 processor with 802.11b/g/n WiFi 4 USB Input – USB type-A female port supporting 3.5V to 20V up to 5A (100 Watts max) USB Output – USB type-A male port up to 100W Misc On/off button – Pressing 5 seconds also change the pairing mode between AP mode and “touch mode” LEDs – …

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 …

BlitzWolf Inexpensive & Compact EU & US Smart Sockets Work with ESPurna & Sonoff-Tasmota Open Source Firmware

BlitzWolf US / EU Smart Socket

When I first started to look into WiFi smart sockets a few years, there were some fairly compact models such as the Linux based Kankun KK-SP3 or ESP8266 based Konke Mini K sockets. In recent years, more wireless smart sockets have come to market, but fewer companies have made compact models, and for example Sonoff S26 or Sonoff S31 smart sockets are not exactly small. But this morning I got contacted by a company called BlitzWolf that sells various accessories including low cost and compact smart sockets for the US and EU markets. It could prove to be interesting, so let’s check out the specifications: BlitzWolf BW-SHP1 US Smart Socket Rated Voltage – 110-240V @ 50-60 Hz Rated Current – 10A (Max) Max Total Power Output – 2000W Dimensions – 4.5 cm ∅ (VO fireproof material) Temperature Range – -10 to +60°C BlitzWolf BW-SHP2 EU Smart Socket Rated Voltage – 110-240V @ 50-60 Hz Rated Current – 16A (Max) Max …

$10 H801 WiFi RGB LED Controller Supports Sonoff-Tasmota Open Source Firmware

H801 WiFi LED Controller

This week-end, I played with ANAVI Light Controller, an open source hardware solution based on ESP8266 used control 12V RGB LED strips. The board has the advantage of being open source with KiCad schematics, Arduino firmware, and HTML5 server program available, so easy to get started and modify the features as you see fit, and it also supports external I2C sensors via three headers. That’s a low volume project made in Eastern Europe and as a result the board costs $25, so I was shortly made aware there were cheaper solution, and if you are ready to mess around a little bit, H801 WiFi controller appears to be one of the most interesting solution as it sells for under $10 shipped on Aliexpress or eBay, and is officially supported by Sonoff-Tasmota open source firmware. H801 specifications: Connectivity – 802.11 b/g/n WiFi (2.4GHz) with about 10 meter range Output – 5x PWM (R, G, B, W1, W2) each up to 4A, …

Review of Sonoff B1 Smart RGB Light Bulb – Part 2: Sonoff-Tasmota Firmware

I’ve already reviewed Sonoff B1 light bulb using the stock firmware combined eWelink app for Android, and as promised in the first part of the review, I’ve also tested the ESP8285 based WiFi light bulb with Sonoff-Tasmota open source firmware, and report my findings in this new post. Before we can play with the new firmware, we need to install it, and I’ve just explained how to upgrade Sonoff devices to Sonoff-Tasmota firmware either using some soldering skills and a USB to serial board, or some network configuration skills and perform an OTA update using ITEAD Studio/eWelink original firmware update mechanism. So for this part of the review, I’ll assume we have just freshly update the light bulb with Sonoff-Tasmota using the binary images released by the developer. First, you’ll need to find the IP address of the light bulb with your router or tools like nmap or arp, and access the web interface in your web browser with for …

Upgrading Sonoff Stock Firmware to Sonoff-Tasmota – USB to Serial, and OTA Update Methods

This post was initially supposed to be part 2 of Sonoff B1 light bulb review, where I would have explained how easy it was to use OTA mechanism to update to Sonoff-Tasmota open source firmware, and shortly show about its features and capabilities. However, it took me over 10 hours to make that work, mostly due to misunderstand in the documentation, and time spent to configure routers. I also failed the first time with Sonoff B1, so I used the serial console method, and instead managed to use SonOTA method with Sonoff POW switching from stock firmware to Sonoff-Tasmota without having to solder or tear down anything. Updating software with a USB to Serial Board Using a USB to serial board is the most common method to switch from stock firmware to open source firmware such as ESPurna or Sonoff-Tasmota in Sonoff devices or other ESP8266 based devices. It’s quite straightforward with Sonoff switches like Sonoff TH16. You just need …

Review of Sonoff RF Bridge, Sonoff 4ch Pro, and Sonoff POW with Sonoff-Tasmota Firmware

Karl here. Today we are going to look at 2 new and one older Sonoff devices. Sonoff RF Bridge – $9.90 433MHz RF to WiFi Bridge Sonoff 4ch Pro – 4 Gang WiFi RF Smart Switch Sonoff POW – Wireless switch with power metering capabilities I spent very little time with the stock firmware on the device. I don’t like the fact that an Internet connection is needed, and I am not in control. As of the time of this writing I found the Ewelink was not configurable enough to meet my needs. There is one feature that is really nice that I could easily see keeping stock firmware. It is the Alexa Skill. It worked. I am also currently reviewing Vobot Smart Alarm Clock with Alexa integration and had no trouble controlling the Sonoff devices with Alexa. But unfortunately I am lazy and want everything automatic so I can’t keep it. With the RF bridge I was unable to …
