ESP32 Alexa PC Power Control
This project uses an ESP32 with the Espalexa library to turn a PC on and off via Alexa voice commands. It works by connecting the ESP32 to the PC’s power switch pins on the motherboard.
How It Works
- The ESP32 connects to WiFi and registers as an Alexa-compatible device.
- Alexa commands trigger a simulated power button press on the PC.
- An optocoupler reads the PC’s power status to determine if it’s on or off.
- The status LED reflects the current power state.
