  • 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)
