Turning On a PC From Far Away

An ESP8266 and a relay wired to the power switch make a PC switchable from anywhere.

Turning a PC on remotely is hard without special network features. An ESP8266 or ESP32 with a relay offers a simple solution: the module stays connected to the internet and closes the relay on the PC's power switch when it receives a command.

I used Arduino IoT Cloud to send the commands and wrote the code that listens for them and triggers the relay. Now I can turn my computer on from anywhere and work on it remotely.
