====== EMS‑ESP Flashing on ESP8266 ======

This page explains the process of flashing the EMS‑ESP firmware on an ESP8266 board (such as a Wemos D1 Mini). Note that EMS‑ESP is a separate firmware designed for ESP8266 devices (as opposed to EMS‑ESP32, which only supports ESP32 chips).

===== EMS‑ESP Firmware =====
  * The EMS‑ESP firmware is maintained in its GitHub repository:
    * [[https://github.com/emsesp/EMS-ESP|EMS‑ESP GitHub Repository]]
  * Download the latest release binary for the ESP8266 from the repository’s releases section.

===== Recommended Flasher Tools =====
Several generic ESP8266 flashers are known to work well with EMS‑ESP:

  * **NodeMCU PyFlasher**
    * A cross‑platform GUI flasher tool.
    * [[https://github.com/marcelstoer/nodemcu-pyflasher|Download NodeMCU PyFlasher]]
  
  * **esptool.py**
    * A command‑line tool by Espressif for flashing firmware.

===== Flashing Procedure =====
  1. **Download EMS‑ESP Firmware:**  
     * Visit the EMS‑ESP GitHub repository and download the appropriate binary for ESP8266.

  2. **Prepare Your ESP8266 Device:**  
     * Connect your ESP8266 (e.g. Wemos D1 Mini) to your computer via USB.
     * Ensure the device is in flash mode. Typically, this is done by holding **GPIO0** (often labeled as D3) low (i.e., connected to ground) during a reset.

  3. **Select a Flasher Tool:**  
     * Open your chosen flasher tool (NodeMCU PyFlasher or esptool.py).
     * Select the correct COM port for your device.

  4. **Flash the Firmware:**  
     * Load the EMS‑ESP binary file into the flasher tool.
     * Start the flash process and wait until the process completes successfully.
