An App receives an SMS and from the text performs a function. For this it is necessary to read the SMS and to make the comparison in the APP, but for this it is due read, word by word, line by line or make a comparison if it contains such a word in this SMS.

SMS will have the following content.

If a status change occurs:
MONIT-110
E05-ATI
E06-DES

And that of all outputs: STATUS-110
E01-DES
E02-DES
E03-DES
E04-DES
E05-DES
E06-DES
E07-DES
E08-DES
E09-DES
E10-DES
E11-DES
S01-DES
S02-DES
S03-DES
S04-DES
S05-DES
S06-DES

For each of these lines you have a different command to execute.

Responsible MSG code received:

public class ReceberSms extends BroadcastReceiver {
    private static final String CATEGORIA = "acqua";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(CATEGORIA, ">" + intent.getAction());

        Sms sms = new Sms();
        //Lê a mensagem
        SmsMessage msg = sms.receberMensagem(intent);
        String celular = msg.getDisplayOriginatingAddress();
        String mensagem = msg.getDisplayMessageBody();
        //pegar essa msg e jogar nas configurações

        String texto = "ReceberSms: recebeu sms[" + celular + "] -> " + mensagem;
        Log.i(CATEGORIA, texto);
        Toast.makeText(context, texto, Toast.LENGTH_SHORT).show();
}

}//fim

It may be necessary to construct it through an object vector. Look at this code:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class ReceiveSMSActivity extends Activity{

    static TextView messageBox;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        messageBox=(TextView)findViewById(R.id.messageBox);
    }

    public static void updateMessageBox(String msg)
    {
        messageBox.append(msg);
    }

}

This one detects and processes the message:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;

public class TextMessageReceiver extends BroadcastReceiver{

    public void onReceive(Context context, Intent intent)
    {
        Bundle bundle=intent.getExtras();

        Object[] messages=(Object[])bundle.get("pdus");
        SmsMessage[] sms=new SmsMessage[messages.length];

        for(int n=0;n<messages.length;n++){
            sms[n]=SmsMessage.createFromPdu((byte[]) messages[n]);
        }

        for(SmsMessage msg:sms){
            ReceiveSMSActivity.updateMessageBox("\nFrom: "+msg.getOriginatingAddress()+"\n"+
                    "Message: "+msg.getMessageBody()+"\n");
        }
    }
}

I think it's missing as another user said, a command, see if you can with this template above.

If the string at the end of your code already contains end of line, message, which you read in the line below:

String mensagem = msg.getDisplayMessageBody();

You can use Split, as already mentioned by @Wakim, by breaking lines and then by '-', and finally a Switch to execute the commands, it would look something like this:

String[] linhas = mensagem.split("\n"); // Veja qual o seu caracter de fim de linha.

for (String l : linhas){
   switch (l) {
         case "E01-DES":
             ...
             break;
         case "E02-DES":
             ...
         case ...

             break;
         default:
             Log.i("ALERTA","Sinal recebido não suportado: " + l);
     }
}

Note that this code is just an example, I would do this function with the Switch outside of FOR, or I would separate each line into two new Strings, and would maybe do a generic function to run each of the strings. actions. But you would need more information from your code for this.
