1. Connect all the modules according to the schematics and make sure to add a 12V APS Unit in case you're using 12V relay modules instead of 5V. You can either solder everything on a THT PCB or use GPIO cables.
  2. Clone the Git repo,open the project with Arduino IDE. Create a new file ,name it WAC.h and put your network creds as shown:
    #define SSID "Wireless Access Point"
#define PW "Password" 
  3. Adjust the UTC offset for your timezone in milliseconds. For example,here's the offset for China which is 28800 ( 8 x 60 x 60 ) 
    NTPClient timeClient(ntpUDP, "asia.pool.ntp.org", 28800, 60000); 
  4. Flash and wait for the board to boot, it'll show the IP as soon as it's online.
  5. Launch a web browser and go to that Address. Make sure that both devices are in the same network.
  6. If you're using electromagnetic relays, then you'll hear a distinct "click" noice when you slide the buttons in the UI. If it's working, hook it up with the stuff you want to control remotely.
  7. Enjoy being lazy~
