Which size resitor is used?

Which size resitor did you use? And which pin did you connect with the bottum? Gnd and a3.

Great job do on the project.

@Heinz Thank you.

I have made this sketch without errors.

@Heinz I know. But is it possible to use A2 and A3?

Hi

Im trying to make an node with BMP085, DHT22 and LM393. Barometer, Temp/hum and light.

Can anyone help me to make the sketch work?

Do the barometer have to be connected to A4 and A5?

@sundberg84 When you desolder are you then removing the komponent? Both led?

Hi

Where to cut in this model pro mine to optimize battery power?

im trying to compare from this link http://www.mysensors.org/build/battery

But they are not the same.

/Nikolaj

I have solved the problem. I changes power supply and now it works.

Can someone recommend some power supply?

How do i change the node number?
It select node 2 all the time with new nodes?

In the sketch they are set to AUTO.

Im using standard sketch from the libery.

The sketch to the relay

How can i Send commands without relays attached? Where i see log from the gatway?
I also tryed change radios. No change.

I have made an temp node and it communicating okay.

@sundberg84 On my gateway (nano) is an 4.7 uF og it is connected with USB to the domoticz. How can I do it different?

It most be an power problem. Is it with the gateway or node?

@hugo_pn Is's possible to see the sketch? Im insecure where to alter the sketch.

Only this is showing when i switch the sensor.

Where do i find the log on gateway? GW log?

It shows everytime when im reset the sensor.

@sundberg84 Where du i find the logs on domoticz?

@sundberg84 My version on domoticz and i have newst version on mysensor.

@sundberg84 No change. Still samme massage.

@sundberg84 Yes standard relay. Present=reset (turn on and off.)?

Hi.

Im new to Domiticz.

I have a problem with sending commands to my sensors.

I have made 1 with one relay and 1 with 4 relay and a scenecontroller.

All of them is refreshing "last seen" when im turning the sensor on and off

Regads Nikolaj

@peka VCC and GND on arduino is 5,337V and from Pin 3-6 to IN1-4 i messurt 4,3V

Update i can trigger the relay when i remove the jumper

A picture of my setup:

@hek The currunt is 0,002A from arduino pin4 to IN2 on the relay board

@sundberg84 Din't work with the GND from the arduino

Update it will only work when it's connected USB to the PC with the monitor program and remove the jumper on the relay board (JD-VCC - VCC current 0,308A).

Hi

Can anyone help me with my relay control?

I can't control my relays without my arduino nano is connected by USB to PC or power supply.

In the setup i already have an 5V 1A power supply connected.

I'm getting this on the vera. I have update the firmware on vera lite.

Hi

I have i problem with inclusion a scener controller to my vera lite with a seriel gateway version 1.4 and 1.5 lib.

When i'm uploading an other sketch to the arduino pro mini and including the sensor it finds the sensor. So it is not an connect problem with the wires.

My sketch look like this:

// Simple SceneController 

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>

#define CHILD_ID 3
// PIN for the buttons
byte buttons[] = {3, 4, 5, 6};
#define NUMBUTTONS sizeof(buttons)
byte pressed[NUMBUTTONS], justpressed[NUMBUTTONS], justreleased[NUMBUTTONS];

MySensor gw;
Bounce debouncer[NUMBUTTONS];

int oldValue[NUMBUTTONS];

MyMessage msgOn(CHILD_ID,V_SCENE_ON);
MyMessage msgOff(CHILD_ID,V_SCENE_OFF);

void setup()  
{  
  gw.begin();

  // Send the Sketch Version Information to the Gateway
  gw.sendSketchInfo("LK 4-Tryk", "1.0");
  // Register binary input sensor to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_SCENE_CONTROLLER);
  
  /// Make input & enable pull-up resistors on switch pins
  for (short i=0; i < NUMBUTTONS; i++){
  
    pinMode(buttons[i], INPUT);
    digitalWrite(buttons[i], HIGH);
    oldValue[i] = -1;
    // After setting up the button, setup debouncer
    debouncer[i].attach(buttons[i]);
    debouncer[i].interval(5);
  } 
}


//  Check if digital input has changed and send in new value
void loop() 
{
  for (short i=0; i < NUMBUTTONS; i++){
    debouncer[i].update();
    // Get the update value
    int value = debouncer[i].read();
 
    if (value != oldValue[i]) {
       // Send in the new value
       if (value==HIGH) {
         gw.send(msgOff.set(i));
       }
       else {
         gw.send(msgOn.set(i));
       }
       oldValue[i] = value;
    }
  }
}

Can anyone help me?

And do anyone have an ide how to make the sketch battery friendly? So it uses as little power as possible.

Thank you.

Of course i delete the line gw.sleep(SLEEP_TIME);

Can anyone help.

/Nikolaj

Solved.
Changes ComFailure to 0 and save device/reload on the plugin.

Update.

I have forgot to choose plugin on seriel port config.

Now the problem only is "Can't Detect Device"

Can anyone help?

That worked. Thank you.

I have update my seriel gateway to vera and delete the device after.

When create new device it constant say:
"MySensors plugin : Choose the Serial Port
MySensors Plugin[90] : Running Lua Startup"

In the device it says:
"Lua Startup Failure.Can't Detect Device"

But it is possible to config in the Serial Port configuration. It is not possible if the seriel gateway where connect to the vera.

What could be the problem?

Thank you.

/Nikolaj

Hey

I get this problem when i'm compiling. No matter what i do. I have tried to delete det libery and indset the new libery.
