Communication problem (maybe)

@hek

Because it looks like that the sleep function is messing with the repeater function. With sleep enabled, almost all messages to the relay actuator node gets lost.

Hmm.. shouldn't affect transmissions. When you removed this line you will get several hundreds of temp readings per second. It is a very big chance a few of them differs which means they will send it to gateway.

You could try adding:
gw.powerUp();
delay(10)
Just before gw.send() to add a small some additional delay after radio powers up.

If you want to keep node awake another option is to use millis() keep track of send frequency. See here:

@hek said:

delay(10)

I assume that is milliseconds, but does that mean that the radio will be powered on during that delay, and will the node repeat incoming messages during that?

If so, I think a much bigger delay would be better, like 30000 or even more.

[hek]

This node isn't configured to be a repeater. So no, it won't.

[Hausner]

It isn't??

hmm... now i'm puzzled!

Cause this is 2 temp nodes

0;0;3;0;9;read: 24-23-0 s=0,c=1,t=0,pt=7,l=5:23.8

My relay actuator is 22

@Hausner do you have any issues with relay node if you are NOT using it also as repeater?

[hek]

If so, I think a much bigger delay would be better, like 30000 or even more.

Yes, thats is actually a third option like you say. Just add a delay(30000) at the end of loop(). (If this node just acts a as a temp sensor and nothing else).

@Hausner I send the temp changes only if change is > 1 deg C and light changes only > +/- 40 lux, have this in main loop:

void loop()     
{     
  // Process incoming messages (like config from server)
  gw.process(); 

  // Fetch temperatures from Dallas sensors
  sensors.requestTemperatures(); 

  // Read temperatures and send them to controller 
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {

    // Fetch and round temperature to one decimal
    float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

    // Only send data if temperature has changed more then 1 degC and no error
    if (int(lastTemperature[i]) != int(temperature) && temperature != -127.00) { //added integer

      // Send in the new temperature
      gw.send(msg.setSensor(i).set(temperature,1));
      lastTemperature[i]=temperature;
    }
  }
  // Read lux from TEMT6000
  float lightLevel = analogRead(LIGHT_SENSOR_ANALOG_PIN) * 9.765625;  // 1000/1024
  if (int(lightLevel - lastLightLevel) > 40 || int(lastLightLevel - lightLevel) > 40) {
      gw.send(msg.setSensor(CHILD_ID_LIGHT).set(int(lightLevel),1));
      lastLightLevel = lightLevel;
  }
  //gw.sleep(SLEEP_TIME); //no sleep for relays!!!!
}

Hope this helps, Pego

As you can see i'm getting way more than 1 reading a second. I think this is happening because of the rounding up/down of the temperature readings.

Yes, clear, if you do not want this you need to change the if to something like:

if (abs(lastTemperature[i] - temperature) >= 0.5 && temperature != -127.00) {

@daulagari

Thank you. I'm gonna try with this

if (abs(lastTemperature[i] - temperature) >= 0.2 && temperature != -127.00) {
