Introduction: Flashing SONOFF Tasmota Firmware on NodeMCU
Sonoff is a WiFi controlled switch which is embedded with ESP8266 IC and has relays to control the device via the Internet. This IC can be flashed and reprogrammed by Arduino IDE. The makers of Sonoff published the libraries and Arduino files on their GitHub page. Initially, it has only for Sonoff made boards only, after that it supports many ESP8266 boards and Development boards like NodeMCU. In this tutorial, we will see how to flash the Sonoff Tasmota Firmware into the NodeMCU development boards. In the new updated firmware, you can easily choose the different ESP8266 Boards easily.
Step 1: Components Needed - Prerequisites
- NodeMCU Development Board
- microUSB Cable
- Sonoff Tasmota Firmware – GitHub Link
- Advanced IP Scanner
- Arduino IDE
Download the Sonoff Tasmota Firmware from this link.
Make sure you have the ESP8266 Library installed on your Arduino IDE. If you want to know how to install ESP8266 library properly visit this complete blog of Flashing SONOFF Tasmota Firmware on NodeMCU.
Step 2: Include Sonoff Libraries to Arduino IDE
Once the SONOFF Tasmota Firmware is downloaded from GitHub. Open the Sonoff Tasmota folder. Navigate to ‘lib’ folder and copy all the contents, then paste it into Arduino ‘libraries’ folder on your computer.
Now we included the necessary library files into Arduino IDE Library. Let's configure our code.
Step 3: Sonoff Main File and User Config
Inside the downloaded file, Open the sonoff.ino file. It will open all the necessary files in next tabs in Arduino IDE. Now open the userconfig.h tab to enter our Wi-Fi Credentials.
Step 4: Configure SSID, Password and Project Name
Now edit the SSID and Password fields with your WiFi network SSID and Password. Also, give a unique project name by your choice in #define PROJECT “sonoff” line.
Eg. #define PROJECT “nodefactory”
Step 5: Choose the Correct NodeMCU Board
Now connect your NodeMCU and choose the correct COM Port and Board Version. Make sure the settings are like this for NodeMCU 1.0 Board.
Board: NodeMCU 1.0 (ESP12-E Module)
Flash Size: “4M(1M SPIFFS)
CPU Frequency: 80 MHZ
Upload Speed: “115200”
Then Flash the Firmware by clicking Upload.
Step 6: FInd NodeMCU IP Address on Your Network
Once Flashing is done Open Advanced IP Scanner . And search for the IP address inside your network IP. In my case, My IP will range from 192.168.255.0-255 (Means the IP will be range from 0-255). Click scan and you can see the project name you given in the userconfig.h file as device name here.
Note down the IP Address you found and paste it into your browser URL and click enter. It will show the Sonoff Tasmota page to configure your module.
Step 7: Configuration for ESP8266 Boards
By default, it will be in Sonoff Basic. So you need to change it to ‘Generic’ in ‘Configuration’ menu. Click ‘Configuration’ and inside that choose ‘Configure Module’.
Step 8: Save the Configuration
Select the board as Generic and Save. The device will restart. This option is for all ESP8266 boards.
Step 9: New GPIO Options According to the ESP8266 Board Types
Now if you click the configuration, then you can able to see more GPIO options. Using that you can select the GPIO Functions.
Depending on the GPIO setting the option will appear on the Homepage like DHT, Relay, Switch and Many more.

I am following the procedure: where is the sonoff.ino file please ?
I am stuck here !
Thanks

there is an tasmota.ino in the tasmota folder that seems to be the one

I found it in lib/esp-knx-ip-0,5,2/examples/sonoff. But it doesn't look like the one above and it doesn't load any other tabs so I'm stuck there. Are these instructions still current?

Hi every one,
I am using the node mcu v3 esp 8266 module to work with the home
automation using the above given Arduino (.ino) code. When i open the
serial monitor After uploading the code successfully , it displays the
following repeatedly.

I know that the module is not connecting with my PC. But not recognize
that why is this error happening. and whats the solution.

Do I have to follow this procedure or will flashing with standard tasmota.bin using ESP Easy or Tasmotizer work?

Maybe someone has a Tasmota ESP8266 connected to Thingsboard MQTT ?

by verifying i get the following error : 'StaticJsonBuffer' was not declared in this scope
what is the problem?

I had to downgrade the ArduinoJson library to 5.13.4 and it worked.

Seems like ArduinoJSON library is not installed or not having a correct version. Some ppl facing problems with Version 6. Check this thread here - https://github.com/bphermansson/EspSparsnasGateway/issues/19

How do i get a created device into eWeLink?
Answer 2 years ago
eWeLink app works only with Official Sonoff devices only. You can create your own using MIT App Inventor

buenas tardes , anduvo de maravillas , como hago para configurar con la app ewelink ? diegorabbia@gmail.com , gracias
Reply 2 years ago
Unfortunately you can't use eWelink app (even flashed this on Original SONOFF) with this firmware. Alternatively you can use many other apps for this like Blynk, MQTT Dash, IFTTT and Many more third party applications. Or You can create your own App using MIT App inventer. All you can do with is your IP Address that you can find with Advanced IP Scanner.

El problema que tengo es que
En off - enciende
On - apaga
0 - enciende
1 - apaga
Como invierto ?
Reply 2 years ago
Are you testing it in D0 On Bord LED? Because in NodeMCU the D0 Pin LED is inverterd. If 0 it turns ON & 1 Turns OFF. Use other Pins.
