[SOLVED] Node sending many messages

[jeti]

Hi

i have combined IR Sending with a SI7021 temperature & humidity sensor.
As i am still new to Mysensors and Arduino i have tweaked to send the temp & humidity once every minute but accept IR orders every 250ms which works fine. My sketch looks like this:

// Enable debug prints
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#define MY_NODE_ID 112

#include <SPI.h>
#include <MySensors.h>
#include <IRLib.h>
#include "Adafruit_Si7021.h"

#include <Wire.h>


#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define CHILD_ID_IR  2  // childId

int counter = 0;

Adafruit_Si7021 sensor = Adafruit_Si7021();
IRsend irsend;

MyMessage msgIR(CHILD_ID_IR, V_VAR1);
MyMessage msgT(CHILD_ID_TEMP, V_TEMP);
MyMessage msgH(CHILD_ID_HUM, V_HUM);

void presentation()  {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("IR Sender & Temp Hum", "1.0");

  // Register a sensors to  Use binary light for test purposes.
  present(CHILD_ID_IR, S_LIGHT);
  present(CHILD_ID_HUM, S_HUM);
  present(CHILD_ID_TEMP,S_TEMP);

  delay(500); // Allow time for radio if power useed as reset
   sensor.begin();
}

void loop() 
{
smartSleep(250); // adjust sleeping time here 250ms in this case 
   ServerUpdate();
   counter ++;
}



void receive(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     int incomingRelayStatus = message.getInt();
     if (incomingRelayStatus == 1) {
      irsend.send(NEC, 0x10C8E11E, 32); // acer Beamer Power
     } else {
      irsend.send(NEC, 0x10C8E11E, 32); // acer Beamer Power
      wait(1000); // Pause zwische zwei mal ausschalten
      irsend.send(NEC, 0x10C8E11E, 32); // acer Beamer Power
     }
  }
}
void ServerUpdate() // used to read sensor data and send it to controller
{
  double T, H;
  T=sensor.readTemperature();
  H=sensor.readHumidity();
  if (counter >= 240){ // 240*250ms = 1minute
      send(msgT.set(T,1));
      send(msgH.set(H,1));
      counter = 0;
  
       
   // unmark for debuging
    //  Serial.print("T = \t"); Serial.print(T, 1); Serial.print(" degC\t");
    //  Serial.print("H = \t"); Serial.print(H, 1); Serial.println(" %\t");
  }
}

It works like it should :smiley: but in debugging mode I see that it seems to send a lot of messages like this:

TSP:MSG:SEND 112-112-0-0 s=255,c=3,t=22,pt=5,l=4,sg=0,ft=0,st=ok:251177

TSP:MSG:SEND 112-112-0-0 s=255,c=3,t=22,pt=5,l=4,sg=0,ft=0,st=ok:257913
TSP:MSG:SEND 112-112-0-0 s=255,c=3,t=22,pt=5,l=4,sg=0,ft=0,st=ok:258473

so i guess it is spaming my setup, or does it?
It would be greate to understand why these messages are sent and how to avoid this.

and once every minute:

TSP:MSG:SEND 112-112-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,ft=0,st=ok:23.1
TSP:MSG:SEND 112-112-0-0 s=0,c=1,t=1,pt=7,l=5,sg=0,ft=0,st=ok:59.2

which is fine

It would be greate to understand why these messages are sent and how to avoid this.

thanks in advance

@jeti I think they may be the heartbeat messages from smartsleep

[jeti]

ah ok, so it is generating traffic which is not needed. Is there a way of smart-sleeping without the hearteat? normal sleep does not work with the recieving part of the sketch...

[mfalkvidd]

@jeti without the heartbeat the controller wouldn't know when the node is awake, so the controller wouldn't know when to send the message.

[jeti]

@mfalkvidd : ok thanks i think i got it now.
As i only want to send the temperature and humidity once every x seconds/minutes, but the IR must be always ready for receiving/sending i can not use sleep (otherwise the sensor only sends when the nod is awake.

I have now used

wait

which does the trick :smiley: : So temp and hum only every minute but IR signals whenever i want. Is "wait" the right tool here or a band aid?

thanks!

[mfalkvidd]

@jeti wait is the correct solution.
