Door, Motion and Temperature Sensor

[CaptainZap]

Can anyone share their thoughts ? I've been running two identical nodes, with no temperature output for a few days now :(

[Dwalt]

@CaptainZap Did you delete the original devices from Vera after you changed the code? I had something similar happen when I rewrote a sketch to modify battery monitoring and Vera would not show the new data. I deleted the node and child devices and reincluded them from scratch and then it worked.

[m26872]

I think you have to redo inclusion of the sensors if you want them to use the repater in their routing. At least it looks like this when I setup my Vera and sensors.

[CaptainZap]

@Dwalt @m26872 Thanks for the feedback, I did do that on the Vera unit. I've even removed the plugin files and re-did everything. I even, and this is a bit extreme, cleared the eprom on the gateway and reflashed it. None of it worked, I really have no clue what to do next. I'm open to every suggestion :D

[Dwalt]

@CaptainZap It your sketch you have this line:
#define ONE_WIRE_BUS 14

What pin is your Dallas sensor connected to?

[m26872]

First make sure a pure repeater node is working. With only the gw.process() to run, it should be fast to enough catch any new inlusion before the gateway. With a proper range of course. Clear the sensors eeprom and Vera-device before reinclusion, but you should not need to do anything with the gateway.

One sensor is connected to A0(14) the other is connected to D5 as it can be seen in my last sketch. Temperature reporting worked on, in my original sketch, however the sketch wasn't perfect so I improved it based on feedback.

@m26872 The sensor is on a breadboard 5cm from the gateway, and I'm not sure about the repeater part...

[CaptainZap]

Well since nobody knew what the problem is I thought I would re-flash my first sketch which was working properly... however after doing it it no longer works... this is blowing my mind away. I don't understand why that would be, as the only changes I've done are listed in this thread, major one was that I upgraded lib to 1.4.1 from 1.4. Anyone has any ideas cause this is driving me crazy now :(

[Moshe Livne]

@CaptainZap would suggest to clear the eeprom

[m26872]

Did you ever get a repeater-only node to work in your mys network ?

[CaptainZap]

@Moshe-Livne @m26872 : I did clear the eprom, I've tried everything I could think of... I'm not quite sure if the repeater works, so far everything is at the breadboard state, so I was pretty much prototyping.

[m26872]

@CaptainZap said:

@AWI Yes I want all my nodes to be repeaters,

Why?
Unless you plan expand your network in the near future, think the increased complexity just will give you trouble.

[Moshe Livne]

@CaptainZap did you clear the eeprom before loading the sketch that used to work?

Hello,

I've read this thread with interest because I want to make my Motion/Temp sensor using Dallas.

Adapting the given code was quite easy (well I guess as I have not tested it for now :D ), I only have changed gw.wait with gw.sleep, because if I understand it correctly, gw.sleep put the sensor in sleep mode which is a bit better for battery :

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

#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID_S1 1   // Id of the sensor child


#define ONE_WIRE_BUS 4 // Pin where dallase sensor is connected 
#define CHILD_ID_T1 2 //CHILD ID for temp


OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature DallasSensors(&oneWire);
float lastTemperature ;
unsigned long SLEEP_TIME = 30000; // Sleep time between reports (in milliseconds)
unsigned long lastRefreshTime = 0;
boolean lastTripped = 0;

MySensor gw;
// Initialize motion message
MyMessage motionMsg(CHILD_ID_S1, V_TRIPPED);
MyMessage tempMsg(CHILD_ID_T1,V_TEMP);

void setup()  
{  
   // Startup OneWire Temp Sensors
    DallasSensors.begin();
    DallasSensors.setWaitForConversion(false);

  gw.begin();

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

  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID_S1, S_MOTION);
  gw.present(CHILD_ID_T1, S_TEMP);
  
}

void loop()     
{
	// Process incoming messages (like config from server)
	gw.process();
	
	// Read digital motion value
	boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 

	if (lastTripped != tripped ) 
	{
		Serial.println("Tripped");
		gw.send(motionMsg.set(tripped?"1":"0")); // Send tripped value to gw 
		lastTripped=tripped;
	}

	boolean bNeedRefresh = (millis() - lastRefreshTime) > SLEEP_TIME;
	if (bNeedRefresh)
	{
		lastRefreshTime = millis();
		DallasSensors.requestTemperatures();
		
		gw.sleep(750);
		float tempC = DallasSensors.getTempCByIndex(1);
		float difference = lastTemperature - tempC;
		if (tempC != -127.00 && abs(difference) > 0.1)
		{
			// Send in the new temperature
			gw.send(tempMsg.set(tempC, 1));
			lastTemperature = tempC;
		}
	}
	else
	{
		gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
	}
}

But I'm concerned about thoses particular lines :

lastRefreshTime = millis();
		DallasSensors.requestTemperatures();
		
		gw.sleep(750);
		float tempC = DallasSensors.getTempCByIndex(1);

Why do we need gw.sleep(750) ? My concern is, when the sensor tries to pull temperature, it could not trigger new motion state for at least 750ms ? This is a problem for me, as I want to use these sensor to trigger light when I come in the room, so I need it to be fast.

Thanks !

@petoulachi said:

this will sleep the device until the interrupt triggers it to awaken...

gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);

you are correct that it seems that the sleep(750) function will block your device, I don't think you want that.

[CaptainZap]

@petoulachi @BulldogLowell Glad to hear there is some progress, in regards to my issue and hopefully this is step in the right direction. I'm positive that we're not alone in our need to create multisensors, both powered and battery operated, as arduinos offer too many possibilities to limit yourself to just a single type of device :)

you don't have a working sketch?

[CaptainZap]

@BulldogLowell Temperature isn't working, and is never updated on the Vera interface :|

[BulldogLowell]

try something like this, which is untested.

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

//myPins
const int PIR_PIN = 3;
const int INTERRUPT = 1;
const int DALLAS_PIN = 4;

//myDevices
const int PIR_SENSOR = 1;
const int DALLAS_SENSOR = 2;

OneWire oneWire(DALLAS_SENSOR);
DallasTemperature DallasSensors(&oneWire);

int lastTemperature = -99;
unsigned long readTempInterval = 60 * 60 * 1000UL;  // One Hour Sleep time between reports (in milliseconds)
unsigned long sleepTime = readTempInterval; 
boolean lastTripped = 0;
boolean sendTemp = true;

MySensor gw;

MyMessage motionMsg(PIR_SENSOR, V_TRIPPED);
MyMessage tempMsg(DALLAS_SENSOR, V_TEMP);

void setup()
{
  DallasSensors.begin();
  //DallasSensors.setWaitForConversion(false);  /I could not get this to compile
  gw.begin();
  gw.sendSketchInfo("Multi-Sensor", "1.0alpha");
  pinMode(PIR_PIN, INPUT);      // sets the motion sensor digital pin as input
  gw.present(PIR_SENSOR, S_MOTION);
  gw.present(DALLAS_SENSOR, S_TEMP);
}

void loop()
{
  //gw.process(); don't need this, it is a one-way device.
  boolean tripped = digitalRead(PIR_PIN);
  if (lastTripped != tripped )
  {
    Serial.println(tripped? "Tripped" : "Not Tripped");
    gw.send(motionMsg.set(tripped)); // Send tripped value to gw
    lastTripped = tripped;
  }
  if (sendTemp)
  {
    DallasSensors.requestTemperatures();
    int tempC = (int) DallasSensors.getTempCByIndex(1);
    gw.send(tempMsg.set(tempC));
    lastTemperature = tempC;
    sendTemp = false;
  }
  unsigned long startSleepTime = millis();
  gw.sleep(INTERRUPT, CHANGE, sleepTime);
  unsigned long endSleepTime = millis();
  if (endSleepTime - startSleepTime >= sleepTime)
  {
    sleepTime = readTempInterval;
    sendTemp = true;
  }
  else
  {
    sleepTime = max(sleepTime -= (endSleepTime - startSleepTime), 1000UL);
  }
}

It will send temp to controller once an hour... you can change that for testing;

also will detect motion...

it may need debouncing.

@BulldogLowell Thanks, I'll try it tonight once I get home.
