Hi im asking for help
I want to program this to automatically restart my modem if internet is down.
Do i ordered the correct item to this project.
Any one help me with the code? I searched online and found this one but i cant manage to keep this work.
Code
#include ESP8266WiFi.h
const char* ssid = "yourssid"; // Your ssid
const char* password = "yourpassword"; // Your Password
const char* testHostname = "www.google.com";
IPAddress HostIP;
unsigned int localPort = 80;
const int RELAY_Pin = 0; //Relay Pin
#define MINUTES (60L * 1000)
#define SECONDS 1000
const unsigned long PROBE_DELAY = 5 * MINUTES;
const unsigned long RESET_DELAY = 15 * MINUTES;
const unsigned long RESET_PULSE = 30 * SECONDS;
int Nreset_events = 0;
enum {
TESTING_STATE=0, FAILURE_STATE=1, SUCCESS_STATE=2
};
int CurrentState = TESTING_STATE;
void setup() {
pinMode(RELAY_Pin, OUTPUT);
Serial.begin(115200);
delay(10);
Serial.println( __FILE__ );
delay(10);
// Connecting to a WiFi network
Serial.print(String("Connecting to ") + ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
delay(500);
}
Serial.println("\nWiFi connected");
}
void reset_device() {
// keep track of number of resets
Nreset_events++;
Serial.println(String("\nDisconnected... resetting - ") + String(Nreset_events));
digitalWrite(RELAY_Pin, HIGH);
delay(RESET_PULSE);
digitalWrite(RELAY_Pin, LOW);
}
void loop() {
switch (CurrentState) {
case TESTING_STATE:
if (!WiFi.hostByName(testHostname, HostIP)) {
CurrentState = FAILURE_STATE;
} else {
CurrentState = SUCCESS_STATE;
}
break;
case FAILURE_STATE:
reset_device();
delay(RESET_DELAY);
CurrentState = TESTING_STATE;
break;
case SUCCESS_STATE:
delay(PROBE_DELAY);
CurrentState = TESTING_STATE;
break;
}
}
