implementing multiple sensors

[Hoffan]

Can anyone see if i have missed something here in the code, It was working great before i copy/past the DHT sensor to the code; ande after that
it will not really work anymore, Its 4 Binary Buttons, 1 relay And 1 DHT sensor Combo

can you elaborate on "doesn't work" ?

do you have sensors on the Vera UI?

Try to debug putting Serial.print(Something) in places so you can see how the sketch progresses...

[Hoffan]

@BulldogLowell

Yes all the sensors came up in the Vera UI, And looks like they work for some minutes
But when i push å button its looks like all things stop working, and after a reboot on the Arduino its working again for a short time and so on

Try threading in the sensor reads into each block to read and change its state in one block for each sensor/pin.

I edited you code so it can be read,,, attached.

Remember AutoFormat under Tools in your arduino menu

void loop() 
{
  debouncer1.update();
  // Get the update value
  int value = debouncer1.read();
  if (value != oldValue1) 
  {
    gw.sendVariable(BUTTON_PIN1, V_TRIPPED, value==HIGH ? "1" : "0");
    oldValue1 = value;
  }
  //
  debouncer2.update();
  value = debouncer2.read();
  if (value != oldValue2) 
  {
    gw.sendVariable(BUTTON_PIN2, V_TRIPPED, value==HIGH ? "1" : "0");
    oldValue2 = value;
  }
  //
  debouncer3.update();
  value = debouncer3.read();
  if (value != oldValue3) 
  {
    gw.sendVariable(BUTTON_PIN3, V_TRIPPED, value==HIGH ? "1" : "0"); 
    oldValue3 = value;
  } 
  //
  debouncer4.update();
  value = debouncer4.read();
  if (value != oldValue4) 
  {
    gw.sendVariable(BUTTON_PIN4, V_TRIPPED, value==HIGH ? "1" : "0");

FourSensorTwoRelay.ino

[waynehead99]

So I have created a multi sensor that uses the DHT and motion to get Temp/Hum/Motion. Problem I have though is the update of the hum/temp. I have not been able to figure out a way to get a reliable update on those without blasting the GW/Vera with unneeded announcements (disable sleep function and it keeps updating pretty much every second). So right now the script updates the temp/hum only when motion is seen. I have tried a few things with my limited knowledge of arduino and can't get this to work properly. Can someone please take a look at this sketch and tell me what I am missing? If i change the variables for sleep at the end and try to do an interrupt and a sleep delay, i get an error.

Motion_Temp_Sensor13b3.ino

[waynehead99]

Nobody wants to take a crack at this? I figured this to be a common combo and would really like to get it to work properly.

I'm coming close to finalising my multisensor sketch. I'll post code once I clean it up a little. I have a newborn at home, so if I forget to put code here then somebody please remind me in a little while :)

Thanks that worked... and for my understanding... looks like your not really using interrupts at all? Looking at the code makes complete sense to me, and proves I was over thinking things on mine.

Thanks again.

The sensor is not running on battery power so I did not spend much time with the interrupt/sleep options.

[Tibus]

is it the same process with the new 1.4 library version?

Could you please give us a exemple here or on github to have multiple sensor type on the same arduino with the new 1.4 library?

if it's the same implementation, we could write multiple "gw.present(ID, XXXX);" and send a message for each child ID type?

Thank's very much.

[Tibus]

Sorry, I found the new implementation in the "DallasTemperatureSensor" Example

[mountainman]

Here is a version I'm currently using that makes use of interrupts so might be more suitable for a battery driven DHT/Motion multi sensor. It also includes the battery monitoring. Any feedback or improvements would be appreciated.

How did you get 3 options for the sleep interrupt? Whenever I would try and add the sleep_time option it would give me compile errors.

[Tibus]

@mountainman
Thank you verry much, exactly what i need!

For child's id, if you have two sensor you have to change the ID in the second?

Sensor 1 :
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define CHILD_ID_MOTION 2

Sensor 2:
#define CHILD_ID_HUM 3
#define CHILD_ID_TEMP 4
#define CHILD_ID_MOTION 5

[mountainman]

@waynehead99 Are you using the new 1.4 Lib?

[Nuubi]

@egbertje Good Question :-) It would be nice to learn from existing working sketches..

[Anticimex]

@waynehead99 you most likely need 1.4 Lib for the new sleep constructor. I have not used sleep on 1.3 so I do not remember what arguments you had available there.
I have also extended sleep with an additional constructor which @hek has pulled into the release branch of 1.4 that permits you to use two external interrupts with independent triggers for sleep in addition to a timeout. Great for nodes with multiple sensors that still run on battery.

[egbertje]

@Mountainman ;

Im trying your code and its almost what im looking for.
I have two questions about it:
1 : Is it possible that the battery info has is own child id?
2 : Why dont you implement a light sensor like an LDR?

I think that including LDR/light then you have the ideal multisensor ; light + temp/hum + motion + batt monitoring !
But for now im playing with your code and try to implement light.
