In this very short tutorial, I will show you how I flashed an ESP8266 with Tasmota.

Step 1: Download ESP Flasher & Tasmota

• ESP Flasher: github repo, and download the appropriate version of ESP Flasher (no need to install)
• Tasmota: tasmota.bin.gz

Step 2: Plug ESP8266 to your computer in Boot Mode

Plug the ESP8266's USB to your computer, while pressing the Flash button

Step 3: Start and Setup ESP Flasher

• Reload the Serial Port until you see your USB plug appearing
• Browse the firmware Tasmota we downloaded in Step 1
• Launch ESP-Flasher

This process can take up to 30sec. Once done, unplug, and replug the ESP8266 module to your computer or any other source of power.

Step 4: WiFi connection

• Once relaunched, you should see a Tasmota_XXX WiFi appearing in your networks.
• Connect your computer to the Tasmota WiFi
• Connect your WiFi (SSID + Password)
• Click Ok
• Let the component restart

Step 5: Tasmota Config

• Configure MQTT Broker accordingly (host + port + login + password)
