This app is written for my NAS server and supports only one device! It requires a static IP for the WOL server (configured in the source code) and for the device (you need to configure it yourself).
Do you need some device with ESP-8266/ESP-8285 (I use WeMos D1 mini Lite), Blynk application (Scan the application QR!), and device configured for Wake on LAN (I can not help you with that, see bios... use google...) To upload the software, use Arduino IDE with the plug-in installed.
