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

[Maciej Kulawik]

@Michal-Mormon
Yes, exactly! It looks like without scene_off sent from scene controller in domoticz it will be one-time action (since if this scene switch is switched on you cannot switch it on again). You can try to setup automatic switching it off in domoticz.

I added 2 lines and works perfect with Domoticz:

MyMessage scene(KEYPAD_CHILD_ID, V_SCENE_ON);
MyMessage scene2(KEYPAD_CHILD_ID, V_SCENE_OFF); //added line

gw.send(scene.set(keyInt));
gw.send(scene2.set(keyInt)); //added line

@Michal-Mormon awesome!

@petewill Have you updated this code to 2.0 yet? What is different?

@hek
Yes I read but was soooo lazy! I just wanted it already done :grimacing:

I just update one of my old sensors it was a simple single relay. My others are way more complicated! I will give this a try.

Not yet, but I'm slowly working on it. :) The link hek gave is very helpful if you want to try it yourself. It's a good way to learn about the new features in 2.0.

@petewill Any news about the 2.0 code? I am in the process of making scene controllers in the different rooms but can't get it to work.

[petewill]

@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.

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.

[hek]

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

[Łukasz Kostrzewa]

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:

[hek]

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

```
Insert Code Here
```

[Łukasz Kostrzewa]

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.
