@Łukasz-Kostrzewa you are welcome, all thanks goes to @petewill for initial code.

Hi Guys,

I'm so glad that have updated the sketch which i have now been able to compile and get running :-)

But this is the message I get in the serial monitor and I only get these messages when I press button 3?? I am using a single row of four buttons as in the original sketch.

Am I missing something here? I was assuming the message with either be a 1 for a short press and 0 for a long press? I would be really grateful if someone who knows more about this than me is able to help me figure out what's going on?

@Matt-Pitts on 3 is short press and in code is scene on and on long press is 7 scene off

MyMessage scene(KEYPAD_CHILD_ID, V_SCENE_ON); //scene ON
MyMessage scene2(KEYPAD_CHILD_ID, V_SCENE_OFF); //scene OFF


        send(scene2.set(keyInt));
      } else {
      send(scene.set(keyInt));```

Hi Not sure if that helps me, I'm struggling to understand how this actually works? as I said the only button doing anything is 3, do I need to modify the sketch to get the other buttons working?

[rechin304]

@Matt-Pitts then you need to check your conenction to all wires and if are correctly. Check first post as there is a picture.

@rechin304

Not getting the Hold on buttons working, everything else works. Any ideas why the long press doesn't work?

[DrJeff]

Never mind part of the code was commented out. I wasn't sure because I just started to use OTA. But it's all good now its working fine. Here it is:

#define MY_DEBUG
#define MY_RADIO_NRF24
#define MY_OTA_FIRMWARE_FEATURE

#include <SPI.h>
#include <MySensors.h>
#include <Keypad.h>

#define NODE_ID AUTO // or set to AUTO if you want gw to assign a NODE_ID for you.
#define SN "Scene Controller"
#define SV "2.0"
#define KEYPAD_CHILD_ID 95

MyMessage scene(KEYPAD_CHILD_ID, V_SCENE_ON); //scene ON
MyMessage scene2(KEYPAD_CHILD_ID, V_SCENE_OFF); //scene OFF

const byte ROWS = 4; //four rows
const byte COLS = 1; //one column
char keys[ROWS][COLS] = {
  {'1'},
  {'2'},
  {'3'},
  {'4'}
};

byte rowPins[ROWS] = {6, 7, 4, 5}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {8}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
byte lastState;


void setup() {
  
  sendSketchInfo(SN, SV);
  present(KEYPAD_CHILD_ID, S_SCENE_CONTROLLER);
  keypad.addEventListener(keypadEvent);
}

void loop() {
  char key = keypad.getKey();
}

void keypadEvent(KeypadEvent key) {
  switch (keypad.getState()) {

    case PRESSED:
      lastState = 1;
      break;

    case HOLD:
      lastState = 2;
      break;

    case RELEASED:
      int keyInt = key - '0'; //Quick way to convert Char to Int so it can be sent to controller
      if (lastState == 2) {
        keyInt = keyInt + 4; //If button is held, add 4.  If using more than 4 buttons this number will need to be changed
        send(scene2.set(keyInt));
      } else {
      send(scene.set(keyInt));
      }
      break;
 }
}

@DrJeff ok, glad to hear you solved.

Hello,

Here an update of the original sketch with a small modif to add a buzzer for validating the keypress.

It will beep once for short key press and twice for the long one.

The buzzer is connected on D3 and the beep length can be adjusted in the function.

Your feedback and improvement ideas are welcome.

Best regards,

Jef

I want to use this mysensors touch sensor to adjust a selector switch in domoticz, so if I select scene 1 the selector switch in Domoticz goes to 10%, and scene 2 to 20% and so on. Is that possible and how do I do that?
