Serial gateway with several sensors connected to it

[skatun]

@TimO
I will look into it, however first I need to get the gateway up running.

So I am struggling to see how locally attached sensors work. I guess (reading several forum entry) that gw object is not needed. What is this inclusion mode? Is that part of the code needed?

However I can not get my code to compile:

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


// Enable debug prints to serial monitor
#define MY_DEBUG 


// Enable serial gateway
#define MY_GATEWAY_SERIAL

// Flash leds on rx/tx/err
#define MY_LEDS_BLINKING_FEATURE
// Set blinking period
#define MY_DEFAULT_LED_BLINK_PERIOD 300

// Enable inclusion mode
#define MY_INCLUSION_MODE_FEATURE
// Enable Inclusion mode button on gateway
#define MY_INCLUSION_BUTTON_FEATURE

// Set inclusion mode duration (in seconds)
#define MY_INCLUSION_MODE_DURATION 60 
// Digital pin used for inclusion mode button
#define MY_INCLUSION_MODE_BUTTON_PIN  3 


#define DIGITAL_INPUT_SENSOR 3  // The digital input you attached your light sensor.  (Only 2 and 3 generates interrupt!)
#define PULSE_FACTOR 1000       // Nummber of blinks per KWH of your meeter
#define SLEEP_MODE false        // Watt-value can only be reported when sleep mode is false.
#define MAX_WATT 10000          // Max watt value to report. This filetrs outliers.
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID 9              // Id of the sensor child
unsigned long SEND_FREQUENCY = 20000; // Minimum time between send (in milliseconds). We don't wnat to spam the gateway.
MySensor gw;
double ppwh = ((double)PULSE_FACTOR)/1000; // Pulses per watt hour
boolean pcReceived = false;
volatile unsigned long pulseCount = 0;   
volatile unsigned long lastBlink = 0;
volatile unsigned long watt = 0;
unsigned long oldPulseCount = 0;   
unsigned long oldWatt = 0;
double oldKwh;
unsigned long lastSend;
MyMessage wattMsg(CHILD_ID,V_WATT);
MyMessage kwhMsg(CHILD_ID,V_KWH);
MyMessage pcMsg(CHILD_ID,V_VAR1);


void setup()  
{  
    attachInterrupt(INTERRUPT, onPulse, RISING);
    lastSend=millis();
}


void presentation() {
  // Present locally attached sensors here
  
    // Register this device as power sensor
    gw.present(CHILD_ID, S_POWER,"Energy Meter");
}

void loop()     
{ 
  gw.process();
  unsigned long now = millis();
  // Only send values at a maximum frequency or woken up from sleep
  bool sendTime = now - lastSend > SEND_FREQUENCY;
  if (pcReceived && (SLEEP_MODE || sendTime)) {
    // New watt value has been calculated  
    if (!SLEEP_MODE && watt != oldWatt) {
      // Check that we dont get unresonable large watt value. 
      // could hapen when long wraps or false interrupt triggered
      if (watt<((unsigned long)MAX_WATT)) {
        gw.send(wattMsg.set(watt));  // Send watt value to gw 
      }  
      //Serial.print("Watt:");
      //Serial.println(watt);
      oldWatt = watt;
    }
  
    // Pulse cout has changed
    if (pulseCount != oldPulseCount) {
      //gw.send(pcMsg.set(pulseCount));  // Send pulse count value to gw 
      double kwh = ((double)pulseCount/((double)PULSE_FACTOR));     
      oldPulseCount = pulseCount;
      if (kwh != oldKwh) {
        gw.send(kwhMsg.set(kwh, 4));  // Send kwh value to gw 
        oldKwh = kwh;
      }
    }    
    lastSend = now;
  } else if (sendTime && !pcReceived) {
    // No count received. Try requesting it again
    request(CHILD_ID, V_VAR1);
    lastSend=now;
  }
  
  if (SLEEP_MODE) {
    sleep(SEND_FREQUENCY);
  }
  
}

void incomingMessage(const MyMessage &message) {
  if (message.type==V_VAR1) {  
    pulseCount = oldPulseCount = message.getLong();
    //Serial.print("Received last pulse count from gw:");
    //Serial.println(pulseCount);
    pcReceived = true;
  }
}

void onPulse()     
{ 
  if (!SLEEP_MODE) {
    unsigned long newBlink = micros();  
    unsigned long interval = newBlink-lastBlink;
    if (interval<10000L) { // Sometimes we get interrupt on RISING
      return;
    }
    watt = (3600000000.0 /interval) / ppwh;
    lastBlink = newBlink;
  } 
  pulseCount++;
}

@skatun it looks like you are mixing the development version 2.0 and master branch 1.5 syntax. In development the "class" setup is removed and therefore for "gw." is not used anymore.

Most of the examples use the gw. Structure though. Look at the samples in the development branch as you will probably want/need the new functionality

[skatun]

@AWI
So I copied ower evrything in the library folder of the development branch. When i then try to compile the serial gateway i get this error:

Arduino: 1.6.7 (Windows 7), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Serial, 115200, 4M (3M SPIFFS)"

@skatun It's hard to tell (for me ;-)) from the messages what is going wrong. Which Arduino are you programming for? Are you using the "GatewaySerial.ino" sketch from the development branch examples?

[skatun]

@AWI
I just copied all the files in libraries and hardware in the development zip into c:\program files\Arduino\

I am trying to get it to run on arduino due and yes I was trying the run the Serial gateway in Library\My Sensor\SerialGateway

[skatun]

@AWI How do I Install the development branch correctly? Does it only work with nano 328?

[sundberg84]

Hi @skatun did you check this http://www.mysensors.org/about/arduino#installing-the-sensor-libraries ? You install it the same way but download it from https://github.com/mysensors/Arduino (press Download ZIP) and make sure its Branch: Development.

[skatun]

@sundberg84

Well I tried to save it both here:
C:\Program Files (x86)\Arduino\libraries\Mysensor
C:\Program Files (x86)\Arduino\hardware\MySensors

As well as here as described in your link:
C:\Users\kim\Documents\Arduino

But I get compile errors no matter where I try to compile serialgateway on due which I found in the C:\Program Files (x86)\Arduino\libraries\MySensors\examples\SerialGateway

Cheers

@skatun having the files in multiple folders isnt a good idea.
Maybe you should remove the IDE and all folders and start over?

[skatun]

@sundberg84
So the IDE by default get installed C:\Program Files (x86)\Arduino but the files folder get default set to this:

C:\Users\kim\Documents\Arduino

I guess arduino made it that way so that you can load examples from C:\Program Files (x86)\Arduino then mess around with them and save them here C:\Users\kim\Documents\Arduino

So I never had duplicate files, i tried both locations without sucsess. So which version of the IDE should I use? 1.6.7 is what I have now.

[sundberg84]

@skatun Dont know if there are any version conflicts at the moment.
I dont have the latest version.

[skatun]

@sundberg84
So which directory should i put the files in? BOth hardware and library?

[sundberg84]

I install the ide. download and extract mys to same path as ide. That's it.

[skatun]

@sundberg84

I will then delete C:\Users\kim\Documents\Arduino which the ide creates.. Will upgrtade today, and let you know how it goes

[barduino]

@skatun

Default libraries included in the IDE

User libraries

Its not uncommon to have compile issues when:

• The IDE is not restarted after uncompressing/copy file to the libraries

• When upgrading MySensors without deleting the old version first

I have Arduino IDE 1.6.4

Cheers

@barduino
Upgrading to Arduino 1.6.8 did the trick.
Thanks.
