Great, thanks for your reply and help.
I was able to do what I wanted, I give you some code snippets to make several messages via a for loop,
I'm not a code proffesional but this works:

// Initialize messages
MyMessage msgInA(0,V_CURRENT);
MyMessage msgWhA(0,V_WATT);


#define NSENSORS              6				//used current sensors

void setup()
{  
	//initialize energy monitor CurrentSensor
	for (int i=0; i<NSENSORS; i++)
	{   
		wh[i]        = { 0.0 };  //initialize wh
		lwhtime[i]   = {0};	//initialize time
		present(i, S_MULTIMETER);  
	}  
	for (int i=0; i<NSENSORS; i++)
	{  
		present(i, S_POWER);
	}
}


	
void loop()
{
  	for (int i=0; i<NSENSORS; i++)
	{
		send(msgInA.setSensor(i).set(Irms[i], 1));
		send(msgWhA.setSensor(i).set(wh[i], 1));    
	}
}

Thanks

Hi there,
I am currently working on a node with openEnergy Monitor.
I'm measuring a total of 6 SCT013 current transformer and wondering how in the mySensor code to include everything in a for loop.
For example, to send the message, I hope to do:

[...]

MyMessage msgInA0(CHILD_ID_V_A0, V_WATT);
MyMessage msgInA1(CHILD_ID_V_A1, V_WATT);
MyMessage msgInA2(CHILD_ID_V_A2, V_WATT);
MyMessage msgInA3(CHILD_ID_V_A3, V_WATT);
MyMessage msgInA4(CHILD_ID_V_A4, V_WATT);
MyMessage msgInA5(CHILD_ID_V_A5, V_WATT);
#define NSENSORS   
           6
[...]
	
//Read values and send to gateway
for (int i=0; i<NSENSORS; i++)
{
	watt[i] = (emon[i].calcIrms(1480))*230*0.9;
	send(msgInA[i].set(watt[i], 1)); //Error: not working
}

But it doesn't work.
Do you have a trick to avoid writing the same code X times?
Thank you,

Thanks for the answer, I keep the advice.
Finally I looked for a while and the problem was with the MQTT publish syntax.
It works perfectly, the difficulty is to find the right publish MQTT request.
Thank you.

Hi all,
I don't understand a problem,
My receive function is not working in the sktech relayActuator.ino
If I simply add the following code :

....
void receive(const MyMessage &message)
{
   Serial.print("--- Incoming Message ---");
  // We only expect one type of message from controller. But we better check anyway.
  if (message.getType()==V_STATUS) {
....

I never have anything.
But in the node logs I do receive the information:
Relay OFF :

345110 TSF:MSG:READ,0-180-162,s=180,c=3,t=6,pt=0,l=1,sg=0:0

Relay ON:

355655 TSF:MSG:READ,0-180-162,s=180,c=3,t=6,pt=0,l=1,sg=0:1

For information I use a gateway+W5100 in MQTT.

An idea why the receive function is not working here ?

Thank you all
