How To: Make a Simple/Cheap Scene Controller (with video)

@dvr123 No, not yet :grimacing:
My thermostat project has taken priority over everything because I need one in my house. I have a prototype working but I need to finish it. It is taking much longer than expected and I also haven't had much time lately. Sorry.

Matt Pitts

Hi Guys,

I've been trying to compile this sketch without any success. I keep getting the following error when compiling

#error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

Can anyone help? thanks

petewill

@Matt-Pitts I still haven't had time to convert/test the sketch for version 2.0. If you want to take a shot at it there is info here: https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x

I will get to it eventually I just have other projects that are consuming my time right now. Sorry.

This post is deleted!

Why is Lukas' post deleted? I have got it in the mail and it seems to compile correctly.
The only thing is that Domoticz only recognizes the button on the first click, after that Domoticz isn't receiving anything.

Not sure why @Łukasz-Kostrzewa deleted it. As an administrator, I can still see the post.

Hi
I delated my post because it pasted wrong. I try to paste it correctly but don't know how:( (hek - maybe You as an administrator can paste it corectly?)

dvr123 have right that this code recognize the buton only on the first click:(
Mayby someone knows how to modify the code to work like normal buton (not the scene controller)?

Best regards

dvr123

I am okey with the scene button, but it has to work more than one time :smile:

@Łukasz-Kostrzewa, paste code within 3 backtick characters, like this:

```
Insert Code Here
```

You could do that but it is not a great solution.
Add to Domoticz all 8 switches (4 when pressed and 4 when hold).
In first switch (pressed switch) add Slave device (first hold switch). Do it for all 4 switches.
To 5,6,7,8 switches add Slave Device (1,2,3,4 switch).
It works like that:
When You press First number on keyboard it change state to ON and 5 to OFF
When You Hold first number on keybord it change state of 5 switch to ON and first to OFF.
Next You have to make some events to trigger some scenes or lights
I have hope I managed to explain what I mean :)
Best regards

The 2.0 version code:

#define MY_DEBUG
#define MY_RADIO_NRF24

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

#define NODE_ID 14 // or set to AUTO if you want gw to assign a NODE_ID for you.
#define SN "Scene Controller"
#define SV "1.0"
#define KEYPAD_CHILD_ID 95

MyMessage scene(KEYPAD_CHILD_ID, V_SCENE_ON); 
MyMessage scene2(KEYPAD_CHILD_ID, V_SCENE_OFF); 

const byte ROWS = 4; //four rows
const byte COLS = 1; //three columns
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(scene.set(keyInt));
      break;
 }
}

dvr123

That's actually much easier! But how do we manage to get it working more than one time? Because I can add the button but after that I can't control it. I can't see the button presses in the Domoticz log either.

send(scene.set(keyInt));

Hi
After
send(scene.set(keyInt));
Add
send(scene2.set(keyInt));
Write this code to arduino (now You can OFF all the switches) Next delete code You added and write it to Arduino once again but now in Domoticz make modifications I writed couple post higher. When You do that You will be able to control 4 scenes and another 4 will bo halpefull to OFF the first4 (when You hold the buttons)

Complete code version 2 with short press ON long press OFF.

#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;
 }
}```

Hi rechin304
Thank You for Your code...It's working great!!!
Best regards

@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.
