⚡ Flashing ESP8266 with Tasmota, in 5 steps

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

Step 1: 📥 Download ESP Flasher & Tasmota

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

Step 3: ⚡Flashing

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

This process could take up to 30 sec.

Once done, unplug, and replug the ESP8266 to the computer or any other source of power.

Step 4: 📡 WiFi Connection
