Hi,
I try to control some relays thr TalkBack app.
Using ESP 8266.
Everything connecting to Internet.
I got stuck on how to activate relay. I used Key, used ID. I cant find how to send command thru TalkBack
I dont know what Command ID for, and how to send command string.
Need some help please
Also here is my code and some screenshots:
#include "ThingSpeak.h"
#include "ESP8266WiFi.h"
const char ssid[] = "XXX"; // your network SSID (name)
const char pass[] = "YYY"; // your network password
#define RELAY1 12
#define RELAY2 13
#define RELAY3 14
#define RELAY4 16
WiFiClient client;
//---------Channel Details---------//
unsigned long counterChannelNumber = 123; // Channel ID
const char * myCounterReadAPIKey = "ZZZ"; // Read API Key
const int FieldNumber1 = 1; // The field you wish to read
const int FieldNumber2 = 2; // The field you wish to read
const int FieldNumber3 = 3; // The field you wish to read
const int FieldNumber4 = 4; // The field you wish to read
//-------------------------------//
void setup()
{
Serial.begin(115200);
WiFi.mode(WIFI_STA);
ThingSpeak.begin(client);
}
void loop()
{
//----------------- Network -----------------//
if (WiFi.status() != WL_CONNECTED)
{
Serial.print("Connecting to ");
Serial.print(ssid);
Serial.println(" ....");
while (WiFi.status() != WL_CONNECTED)
{
WiFi.begin(ssid, pass);
delay(5000);
}
Serial.println("Connected to Wi-Fi Succesfully.");
}
//--------- End of Network connection--------//
//---------------- Channel 1 ----------------//
Serial.print("Reading field 1 ");
long R_Status = ThingSpeak.readLongField(counterChannelNumber, FieldNumber1, myCounterReadAPIKey);
int statusCode = ThingSpeak.getLastReadStatus();
if (statusCode == 200)
{
Serial.print("Read field 1 Successful ");
// Serial.println(temp);
}
else
{
Serial.println("Unable to read channel / No internet connection");
}
Serial.println(R_Status);
if(R_Status==1)
{
digitalWrite(RELAY1, HIGH); //Relay 1 ON
Serial.println("Relay 1 ON");
}
if(R_Status==2)
{
digitalWrite(RELAY1, LOW); //Relay 1 OFF
Serial.println("Relay 1 OFF");
}
Serial.print("Reading field 2 ");
delay(5000);
long R_Status2 = ThingSpeak.readLongField(counterChannelNumber, FieldNumber2, myCounterReadAPIKey);
int statusCode2 = ThingSpeak.getLastReadStatus();
if (statusCode2 == 200)
{
Serial.print("Read field 2 Successful ");
// Serial.println(temp);
}
else
{
Serial.println("Unable to read channel / No internet connection");
}
Serial.println(R_Status2);
if(R_Status2==1)
{
digitalWrite(RELAY2, HIGH); //Relay 2 ON
Serial.println("Relay 1 ON");
}
if(R_Status2==2)
{
digitalWrite(RELAY2, LOW); //Relay 2 OFF
Serial.println("Relay 1 OFF");
}
Serial.print("Reading field 3 ");
delay(5000);
long R_Status3 = ThingSpeak.readLongField(counterChannelNumber, FieldNumber3, myCounterReadAPIKey);
int statusCode3 = ThingSpeak.getLastReadStatus();
if (statusCode3 == 200)
{
Serial.print("Read field 3 Successful ");
// Serial.println(temp);
}
else
{
Serial.println("Unable to read channel / No internet connection");
}
Serial.println(R_Status3);
if(R_Status3==1)
{
digitalWrite(RELAY3, HIGH); //Relay 3 ON
Serial.println("Relay 3 ON");
}
if(R_Status3==2)
{
digitalWrite(RELAY3, LOW); //Relay 3 OFF
Serial.println("Relay 3 OFF");
}
Serial.print("Reading field 4 ");
delay(5000);
long R_Status4 = ThingSpeak.readLongField(counterChannelNumber, FieldNumber4, myCounterReadAPIKey);
int statusCode4 = ThingSpeak.getLastReadStatus();
if (statusCode4 == 200)
{
Serial.print("Read field 4 Successful ");
// Serial.println(temp);
}
else
{
Serial.println("Unable to read channel / No internet connection");
}
Serial.println(R_Status4);
if(R_Status4==1)
{
digitalWrite(RELAY4, HIGH); //Relay 4 ON
Serial.println("Relay 4 ON");
}
if(R_Status4==2)
{
digitalWrite(RELAY4, LOW); //Relay 4 OFF
Serial.println("Relay 4 OFF");
}
delay(10000); // ThingSpeak will only accept updates every 10 seconds.
