Temperature not presented to controller

[Sander Stolk]

Hi there,

I've got this sketch running on a Arduino Nano with a 5V 2.1A powersupply and I cannot get the Temp presented to the gateway.

Below is my sketch and my debug-log:

I'm using 1.4 version in combination with a Arduino Gateway Nano.

Everything else is presented to the controller but not the temperature.
When I build a sketch with only the temp it works but that differs from this code above.

[rvendrame]

You might try to add a capacitor between radio's VCC/GND, if not yet. Another try is to add a gw.wait(100) after each gw.send() (this made the trick for me).
If after that you still getting a lot of st=fails, try replacing PSU / radio.

[Sander Stolk]

Cap is present and I will proceed to add a 100ms delay between those messages.
Otherwise I will replace the radio.

Let you know!

[Sander Stolk]

Implemented the wait time but no luck
Replaced the radio and the cap but no luck
Checked the wires but no luck

Next thing is checking the code because the door is working and comes after the tempsensor.
The reading of the tempsensor says -127.0

Is there somebody who knows what kind of error -127.0 degrees means except my bedroom is very cold

[Tomasz Pazio]

Sander, I have the same issue on my side.
http://forum.mysensors.org/topic/1715/multiple-ds18d20-does-not-report-temperature

[Sander Stolk]

Boom! Got it!

The sketch above does not send the temp because -127.0 / disconnected however with this sketch and implemented in my sketch above and it works...

#include <MySensor.h>  
#include <SPI.h>
#include <DallasTemperature.h>
#include <OneWire.h>

#define ONE_WIRE_BUS 8 // Pin where dallase sensor is connected

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
MySensor gw;
float lastTemperature[MAX_ATTACHED_DS18B20];
int numSensors=0;
boolean receivedConfig = false;
boolean metric = true; 
// Initialize temperature message
MyMessage msg(0,V_TEMP);

void setup()  
{ 
  // Startup OneWire 
  sensors.begin();

  // Startup and initialize MySensors library. Set callback for incoming messages. 
  //gw.begin(); 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("test temp");

  // Fetch the number of attached temperature sensors  
  numSensors = sensors.getDeviceCount();

  // Present all sensors to controller
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
     gw.present(i, V_TEMP);
  }
}


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;
    }
  }
  //gw.sleep(SLEEP_TIME);
}

Same hardware, same libs and different code...
You tell me whats wrong because I don't know it anymore...
