Thanx 😀
The compiling errors are now solved!

Unfortunately the problem is not solved yet, the led L flashes a couple of times when starting and after that it starts to burn softly.
It looks like it stops working after this.

The Nano and Dallas sensors are connected OK, when I check it with a simple sketch I can reed the temperatures through the serial connection.

Hi All,

I am having a problem with compiling the code for 3 Dallas DS18B20 temperature sensors.
I am using the IDE 1.6.12 with fresh library's imported as per these instructions.

The errors are in this piece of code:

 // query conversion time and sleep until conversion completed
  int16_t conversionTime = sensors.millisToWaitForConversion(sensors.getResolution());
  // sleep() call can be replaced by wait() call if node need to process incoming messages (or if node is repeater)
  sleep(conversionTime);

The errors I am getting are as follows:

In file included from C:\Users\johan\Documents\Arduino\examples\DallasTemperatureSensor\DallasTemperatureSensor.ino:37:0:

C:\Users\johan\Documents\Arduino\libraries\DallasTemperature/DallasTemperature.h: In function 'void loop()':

At this moment I am completely clueless on how to continue.

Thanx in advance!

Yesterday I found some example code on the Domoticz forum.

With some modifications I get numbers in wind :smiley:

As below my current sketch that sends values, I will modify it untill it is what I like and will post it here.

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

#define CHILD_ID_WIND 20

#define LED_PIN 8

#define ID_WIND 170

#define WIND_SENSOR_ANALOG_PIN 1

MySensor gw;
unsigned int val_wspeed;
unsigned int val_wgust;
unsigned int val_wdirection;


unsigned int last_wspeed;
unsigned int last_wgust;
unsigned int last_wdirection;


boolean metric = true; 

unsigned long currentTime;
unsigned long SEND_FREQUENCY = 10000;
unsigned long lastSend;

MyMessage msgWSpeed(CHILD_ID_WIND, V_WIND);
MyMessage msgWGust(CHILD_ID_WIND, V_GUST);
MyMessage msgWDirection(CHILD_ID_WIND, V_DIRECTION);

//Setup routine
void setup()  
{ 
  
    // Initialize library and add callback for incoming messages
  gw.begin();

  // Send the Sketch Version Information to the Gateway
  gw.sendSketchInfo("Windsensor", "0.1");

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID_WIND, S_WIND);

  metric = gw.getConfig().isMetric;
  lastSend = 0;

  pinMode(LED_PIN, OUTPUT); 
  digitalWrite(LED_PIN,1);
}

//Main loop
void loop()      
{  
  gw.process();
 
  currentTime = millis();
  
  unsigned int val_wspeed = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
  
    if(last_wspeed != val_wspeed)
    { 
       last_wspeed = val_wspeed;
       gw.send(msgWSpeed.set(val_wspeed, 1));
       Serial.print("WS: ");
       Serial.println(val_wspeed);
    }
    
    unsigned int val_wgust = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
    if(last_wgust != val_wgust)
    { 
       last_wgust = val_wgust;
       gw.send(msgWGust.set(val_wgust, 1));
       Serial.print("WG: ");
       Serial.println(val_wgust);
    }
    
    unsigned int val_wdirection = (analogRead(WIND_SENSOR_ANALOG_PIN))/2.842; 
    if(last_wdirection != val_wdirection)
    { 
       last_wdirection = val_wdirection;
       gw.send(msgWDirection.set(val_wdirection, 1));
       Serial.print("WD: ");
       Serial.println(val_wdirection);
    }
}

@kenci
Ah I checked the manufacturers data again and now see what you mean :)
I will change this, thanx!

JohanRC

My current code that is not sending info is:

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

#define CHILD_ID_WIND 1
#define WIND_SENSOR_ANALOG_PIN 1

unsigned long SLEEP_TIME = 10000; // Sleep time between reads (in milliseconds)

MySensor gw;
MyMessage msg(CHILD_ID_WIND, V_WIND);
float lastWindLevel;

void setup()  
{ 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Wind Sensor", "2.0");

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID_WIND, S_WIND);
}

void loop()      
{     
  float windLevel = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
  Serial.println(windLevel);
  if (windLevel != lastWindLevel) {
      gw.send(msg.set(windLevel, 1));
      lastWindLevel = windLevel;
  }
  gw.sleep(SLEEP_TIME);
}

The code that is sending data (in lux) is:

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

#define CHILD_ID_WIND 1
#define WIND_SENSOR_ANALOG_PIN 1

unsigned long SLEEP_TIME = 10000; // Sleep time between reads (in milliseconds)

MySensor gw;
MyMessage msg(CHILD_ID_WIND, V_LIGHT_LEVEL);
float lastWindLevel;

void setup()  
{ 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Wind Sensor", "2.0");

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID_WIND, S_LIGHT_LEVEL);
}

void loop()      
{     
  float windLevel = (analogRead(WIND_SENSOR_ANALOG_PIN))/31.605; 
  Serial.println(windLevel);
  if (windLevel != lastWindLevel) {
      gw.send(msg.set(windLevel, 1));
      lastWindLevel = windLevel;
  }
  gw.sleep(SLEEP_TIME);
}

I dont really see why my formula is wrong, my sensor output is 0V to 5V in wind ranging from 0m/s to 32,4ms.
This means when I have 5V on the input sensor (32,4m/s) I will measure a value of 1023 when I devide this through 31,605 I will read a value of 32,368 m/s
I have made it a float and rounded it to one decimal, so I dont realy see the problem here (please correct me if I am wrong)

I am more and more suspecting that there might be something going on on the Domoticz side.

JohanRC

@sundberg84
This might be a good tip, I did not add any new node in Domoticz but I waited until would appear automaticly, this ofcourse did not happen. So I need to find out how to manually add a new node in Domoticz. (I am only a 3 days old baby regarding to Domoticz:smile: )

@mfalkvidd
My latest sketch is the one I last posted in post 8.

Already thanks for all the input I am not there yet but I think were getting close :)
When finished I think it would perhaps be a good idea to post the code as an example so more people can have the benefits of it.

@sundberg84
No unfortunatly this is not the problem, the setup is still on my kitchen table so i can "produce wind with my finger" :)

The thing is when I leave the V and S values to "Light" it transfers the data without any problems you can aslo see this in the log file between 07:05 and 07:06.
But when I change it to WIND there is no transfer of data anymore, I can see by the TX light on my Arduino nano that it is sending info.

JohanRC

At 7:08 I changed to the "Wind" code, as you can see it sends its sketch info but nothing more

This is the sketch that is working with just changing the formula:

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

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 0

unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_LIGHT_LEVEL);
int lastLightLevel;

void setup()  
{ 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Light Sensor", "1.0");

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
}

void loop()      
{     
  int lightLevel = (analogRead(LIGHT_SENSOR_ANALOG_PIN))/31.605; 
  Serial.println(lightLevel);
  if (lightLevel != lastLightLevel) {
      gw.send(msg.set(lightLevel));
      lastLightLevel = lightLevel;
  }
  gw.sleep(SLEEP_TIME);
}

And than when I change it like below it doent seem to do anything anymore

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

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 0

unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

MySensor gw;
MyMessage msg(CHILD_ID_LIGHT, V_WIND);
int lastLightLevel;

void setup()  
{ 
  gw.begin();

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Light Sensor", "1.0");

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID_LIGHT, S_WIND);
}

void loop()      
{     
  int lightLevel = (analogRead(LIGHT_SENSOR_ANALOG_PIN))/31.605; 
  Serial.println(lightLevel);
  if (lightLevel != lastLightLevel) {
      gw.send(msg.set(lightLevel));
      lastLightLevel = lightLevel;
  }
  gw.sleep(SLEEP_TIME);
}

I think it is somewhere wrond in comunication text or something (I mean have a resonable amount of experiance in Arduino programming only not in the communication part).

Thanks!

Hmmz, just changing V_LIGHT_LEVEL to V_WIND and S_LIGHT_LEVEL to S_WIND doesnt seem to do the trick.
When these values are changed, Domoticz does not seem to recognize it any more (no new devices or updated lux values).

I think I am missing something here.

JohanRC

Thanks guys I will try to change these valuess :)

For the anemometer I use to following:

Hi,

I am building a wind speed sensor node, but I am having diffictulty's in programming the code since I have not found any example code.
It is probably very easy but hey I am NOOB ;)

The sensor I am using has a 0 to 5V analog output for windspeeds from 0 to 32,4 m/s.
So what I did right now is I took the lightsensor example code and changed the formula to give me the value in m/s instead of lux, this already works.

But now I would also like it that my Domoticz gateway would also see it as a wind speed sensor instead of a light sensor.

Any hints/tips/help would be greatly appriciated!
