/*
First Get library from https://github.com/SensorsIot/NTPtimeESP
and upload library to arduino ide also you will need ESP8266WiFi library and esp8266WebServer libraries
for wifi access!
This sketch shows an example of sending a reading to data.sparkfun.com once per day.
It uses the Sparkfun testing stream so the only customizing required is the WiFi SSID
and password.

Another snippet for / instead of spaces
- Code:
Serial.println("");
Serial.print(dateTime.hour-1);
Serial.print(":");
Serial.print(dateTime.minute);
Serial.print(":");
Serial.print(dateTime.second);
Serial.println("");
Serial.print(dateTime.day);
Serial.print("/");
Serial.print(dateTime.month);
Serial.print("/");
Serial.print(dateTime.year);
Serial.println("");

Add a title to your web server
- Code:
client.println("<title>Wireless Switch</title>");

Now for adding more advanced features like alarm setting!
- Code:
client.println("<a href=\"/ALARM=AL10PM\"\"><button>Turn On Alarm For 22:00</button></a>");
client.println("<a href=\"/ALARM=AL10AM\"\"><button>Turn On Alarm For 10:00</button></a>");
- Code:
int AL1 = 000;
if (request.indexOf("/ALARM=AL10PM") != -1) {
// set alarm ALARM=AL10PM
int AL1 = 22;
}
if (request.indexOf("/ALARM=AL10AM") != -1) {
// set alarm here!
int AL1 = 10;
}
