WLED Remote Control for ESP32 using ESP-NOW Protocol

This project allows controlling WLED devices using an ESP32 over the ESP-NOW protocol, mimicking the functionality of a WiZmote. The ESP32 sends commands wirelessly to the WLED device, and the communication operates efficiently without needing to connect to Wi-Fi.

Features

• ESP-NOW Protocol: Utilizes the low-power, fast, and efficient ESP-NOW communication method to control WLED devices.
• WLED Control: Commands like turning lights on/off, adjusting brightness, and switching presets are supported.
• Touch Sensor Integration: The ESP32 uses a touch sensor (T0) to wake from deep sleep and send control commands to the WLED device.
• Deep Sleep Mode: After sending a command, the ESP32 enters deep sleep to significantly reduce power consumption, making it energy-efficient for long-term usage.

Configuration

1. Set WLED MAC Address:

   • Modify the macAddress[] variable in the code to match the MAC address of your WLED device.

2. Set Wi-Fi Channel:

   • Set the CHANNEL constant to the same channel used by your WLED device.

3. Configure WLED to Listen to ESP-NOW Events:

   • In the WLED web interface, go to Config > WiFi setup.
   • Scroll down to the Wireless Remote section.
   • Enable ESP-NOW Enable Remote and modify the Hardware MAC with the ESP32 MAC address.

Usage

If everything has been configured correctly, when the T0 pin (GPIO4) is touched in the ESP32, the LEDs configured in WLED will turn on/off. The operation can be modified.

Available Functionalities

The ESP32 remote control can trigger the following WLED functions using ESP-NOW:

1. Turn Lights On/Off:

   • Constant: ON (1), OFF (2)
   • Tap the touch sensor to toggle the WLED device between on and off states.

2. Adjust Brightness:

   • Constant: BRIGHT_UP (9), BRIGHT_DOWN (8)
   • Increase or decrease the brightness of the WLED lights by sending brightness control commands.

3. Switch Between Presets:

   • Constants:
     • PRESET_ONE (16): Send preset one command.
     • PRESET_TWO (17): Send preset two command.
     • PRESET_THREE (18): Send preset three command.
     • PRESET_FOUR (19): Send preset four command.
   • Easily switch between four preset configurations in WLED.

4. Night Mode:

   • Constant: NIGHT (3)
   • Activate night mode to dim the lights to a comfortable level for evening or low-light conditions.
