Doorbell hack

[msebbe]

Hi!

Im using a modified version of the Door/Window sketch. I have a random 433mhz doorbell at my door and a arduino nano 3.0 with radio and 433mhz receiver connected.

I have managed to make the node send this message every time the doorbell is pressed

gw.send(msg.set(value == HIGH ? 1 : 0));

Nothing happends in the Vera edge UI tho. I would like to make it so that when doorbell is pushed, same thing happends like when you open the door in the original sketch (red color in Vera UI when door open)

here is full code;

 this is set up for a 4 pin recv unit GND DATA DATA VCC
 plug GND into D2, DATA into D3 and D4, and VCC into D5
*/

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();

#define CHILD_ID 3
#define VCC_PIN 5 // source 5V up to 40mA from this pin
#define GND_PIN 2 // sink up to 40mA on this pin
#define DATA_PIN 3 // external int 1 on Uno

MySensor gw;
int oldValue = -1;
int bell = -251;

// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
  gw.begin();

  // Register binary input sensor to gw (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage.
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  gw.present(CHILD_ID, S_DOOR);

  // 433mhz Part
  pinMode(DATA_PIN, INPUT);
  // just leave D4 tristated

  pinMode(GND_PIN, OUTPUT);
  digitalWrite(GND_PIN, LOW);

  pinMode(VCC_PIN, OUTPUT);
  digitalWrite(VCC_PIN, HIGH);


  mySwitch.enableReceive(1);  // Receiver on interrupt 1 => that is pin D3

}

static unsigned long count = 0;

void loop()
{
  if (mySwitch.available()) {

    int value = mySwitch.getReceivedValue();
    if (value == bell) {
    // Send in the new value
    gw.send(msg.set(value== HIGH ? 1 : 0));
    oldValue = 1;
    

    
  }

    mySwitch.resetAvailable();
    count = 0;
  }
  else {
    if (++count == 0) Serial.println("no activity");
  }

  
}

Any Ideas how I can just make the message so it triggers "door sensor" in my UI?

Guess you'll also have to send/restore the tripped value after some time?

Yes, that would be ideal. First problem for me is how to change tripped value without using the actual magnetic sensor..

Below is my working sketch. Could somebody help clean it up? I made this sketch by combining two sketches and removing some parts from each.

/*

 plug GND into D2, DATA into D3 and D4, and VCC into D5
*/

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();

#define CHILD_ID 3
#define VCC_PIN 5 // source 5V up to 40mA from this pin
#define GND_PIN 2 // sink up to 40mA on this pin
#define DATA_PIN 3 // external int 1 on Uno

MySensor gw;
int oldValue = -1;
int bell = -251;     // This is the value that my 433mhz doorbell sends out when button is pushed

// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
  gw.begin();

  // Register binary input sensor to gw (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage.
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  gw.present(CHILD_ID, S_DOOR);

  // 433mhz Part
  pinMode(DATA_PIN, INPUT);
  // just leave D4 tristated

  pinMode(GND_PIN, OUTPUT);
  digitalWrite(GND_PIN, LOW);

  pinMode(VCC_PIN, OUTPUT);
  digitalWrite(VCC_PIN, HIGH);


  mySwitch.enableReceive(1);  // Receiver on interrupt 1 => that is pin D3

}

static unsigned long count = 0;

void loop()
{
  if (mySwitch.available()) {

    int value = mySwitch.getReceivedValue(); // This is where 433mhz signal are recieved
    if (value == bell) {
    // Send in the new value
    gw.send(msg.set("1"));  // Gives doorbell status tripped
    
    
    delay(5000);
    gw.send(msg.set("0"));  // Gives doorbell status not tripped
  }

    mySwitch.resetAvailable();
    count = 0;
  }
  else {
    if (++count == 0) Serial.println("no activity");
  }

  
}

not tested, but I'd look to do it like this... with non-blocking code in case of a second press of the doorbell within the 5second timeout:

/*
 this is set up for a 4 pin recv unit GND DATA DATA VCC
 plug GND into D2, DATA into D3 and D4, and VCC into D5
*/

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();

#define CHILD_ID 3
#define VCC_PIN 5 // source 5V up to 40mA from this pin
#define GND_PIN 2 // sink up to 40mA on this pin
#define DATA_PIN 3 // external int 1 on Uno

MySensor gw;
const int bell = -251;     // This is the value that my 433mhz doorbell sends out when button is pushed
boolean tripped = false;
// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
  gw.begin();

  // Register binary input sensor to gw (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage.
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  gw.present(CHILD_ID, S_DOOR);
  // 433mhz Part
  pinMode(DATA_PIN, INPUT);
  // just leave D4 tristated
  pinMode(GND_PIN, OUTPUT);
  digitalWrite(GND_PIN, LOW);
  pinMode(VCC_PIN, OUTPUT);
  digitalWrite(VCC_PIN, HIGH);
  mySwitch.enableReceive(1);  // Receiver on interrupt 1 => that is pin D3
}

void loop()
{
  if (mySwitch.available())
  {
    tripped = (mySwitch.getReceivedValue() == bell);
    if (tripped)
    {
      gw.send(msg.set("1"));
      timerStart = millis();
      Serial.println(F("Ding Dong!!"));
    }
    mySwitch.resetAvailable();  //<<<<<<<<<< I think you want this here... I looked at the library on GitHub
  }
  if (tripped && millis() - timerStart > 5000UL)
  {
    gw.send(msg.set("0"));
    Serial.println(F("no activity"));
    tripped = false;
  }
}

again, I could not test it...

Thank you! Looks much better. I will test later today when its not 31 celsius outside :)

OK, I reviewed the arduino library and it looks like mySwitch.resetAvailable(); belonged higher in the code, so I edited it. You may want to be wary of that.

Ok thanks for your effort :+1:

When compiling I get this error below. I think this should be quiet easy to fix but I dont understand this language yet :confused:

sketch_jul03a.ino: In function 'void loop()':
sketch_jul03a:49: error: 'timerStart' was not declared in this scope
sketch_jul03a:54: error: 'timerStart' was not declared in this scope
'timerStart' was not declared in this scope

@msebbe

try inserting:

unsigned long timerStart;

to the header in the next line following:

boolean tripped = false;

Thanks that worked, however nothing happends when I test by using the door bell. I will investigate this when I get home on monday and stick to my old sketch until then .

Hmm, still nothing. It seems to be the 433mhz reciver part that is not working.
