This is a sketch for the M5Atom ESP32 board. A telegram bot is hosted on the board and listens for messages, when the /wol command is received a Wake-on-Lan magic packet is broadcasted on the local network in order to turn on a target device.

🪙 You can keep it running for about 1$ in electricity per year, the power consumption is less than half a watt.

• Install the following libraries from the Library Manager of the Arduino IDE:
  • M5Atom: needed for the M5Atom board
  • WakeOnLan: for sending the magic packet
  • UniversalTelegramBot: for using the Telegram API
• Create a new Telegram bot and configure your BOT_TOKEN and ALLOWED_ID
  You can use @Botfather to create a new bot and @userinfobot to get your ID
• Fill your WiFi configuration and the MAC address of the PC you want to power on
• Compile and flash

• Use /start to get a list of the available commands
• Use the /wol command or press the physical button to turn on your PC
• Use the /ping command to check if the bot is online

• Refactor code
• Store network configuration in EEPROM
• Add configuration commands to Telegram bot
