Array Relay Button Actuator

[jeylites]

@AWI How do I go about doing this?

This is the messages i get from the gateway when actuator is pressed on the sensor node.

0;0;3;0;9;read: 11-11-0 s=0,c=1,t=2,pt=2,l=2:0
11;0;1;0;2;0

11;0;1;0;2;1

@jeylites I was meaning to say.: on the node serial output. Do you see messages coming in. You can also add a print statement in the received message code.

[AWI]

@jeylites I think I found the problem. You won't receive any messages from the controller as messages are not initialized. Replace NULL in the gw. begin by the name of the incoming message routine.. Wonders will start to happen :eyes:

[jeylites]

@AWI . OK let me try again.

@AWI

... This is insane and it works :joy: :smiley: How do you change between HIGH/LOW state. I changed the #define settings but it's not taking effect.

[jeylites]

@AWI

This is the awkward part. On the Vera App & Web, I'm able to toggle ON / OFF to the respective state of the Relay. Eg: "ON" on Vera energize the Relay and "OFF" de-energine the relay. But, when I use the actuator buttons on Arduino input , its reversed. "OFF" turns ON the Relay ...vice versa.

[AWI]

@jeylites I understand your Relays are active low. You have to be consequent in terminology like: on/off; true/false; RELAY_ON/RELAY_OFF. From a first glance I think you should be fine if you change the line:

digitalWrite(Relays[i].relayPin, Relays[i].relayState);

to

digitalWrite(Relays[i].relayPin, Relays[i].relayState?RELAY_ON:RELAY_OFF);

as things get mixed up here. i.e RELAY_ON is in fact "false" or "0"

@AWI

I revised the sketch based on your advice and seem to be working as we speak. I tried to make the final sketch as organized as possible, It has be copied below. Thank you everyone for making this work!!!

#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#define RELAY_ON 0                      // switch around for realy HIGH/LOW state
#define RELAY_OFF 1
//
MySensor gw;

#define RADIO_ID 11                    // radio Id, whatever channel you assigned to
#define noRelays 2
const int relayPin[] = {3,7};          //  switch around pins to your desire
const int buttonPin[] = {4,5};      //  switch around pins to your desire

class Relay				// relay class, store all relevant data (equivalent to struct)
{
public:                             		 
  int buttonPin;			       // physical pin number of button
  int relayPin;				// physical pin number of relay
  byte oldValue;               		// last Values for key (debounce)
  boolean relayState;             	// relay status (also stored in EEPROM)
};

Relay Relays[noRelays];	
Bounce debouncer[noRelays];
MyMessage msg[noRelays];

void setup(){
	gw.begin(incomingMessage, RADIO_ID, true);
	delay(250);
	gw.sendSketchInfo("MultiRelayButton", "0.9b");
	delay(250);

	// Initialize Relays with corresponding buttons
	for (int i = 0; i < noRelays; i++){
	Relays[i].buttonPin = buttonPin[i];			     // assign physical pins
	Relays[i].relayPin = relayPin[i];
	msg[i].sensor = i;						             // initialize messages
	msg[i].type = V_LIGHT;
	debouncer[i] = Bounce();					    // initialize debouncer
	debouncer[i].attach(buttonPin[i]);
	debouncer[i].interval(5);
	pinMode(Relays[i].buttonPin, INPUT_PULLUP);
	pinMode(Relays[i].relayPin, OUTPUT);
	Relays[i].relayState = gw.loadState(i);			                      // retrieve last values from EEPROM
	digitalWrite(Relays[i].relayPin, Relays[i].relayState? RELAY_ON:RELAY_OFF);   // and set relays accordingly
	gw.send(msg[i].set(Relays[i].relayState? true : false));	              // make controller aware of last status
	gw.present(i, S_LIGHT);							      // present sensor to gateway
	delay(250);

	}
}

void loop()
	{
	gw.process();
	for (byte i = 0; i < noRelays; i++){
	debouncer[i].update();
	byte value = debouncer[i].read();
	if (value != Relays[i].oldValue && value == 0){
	Relays[i].relayState = !Relays[i].relayState;
	digitalWrite(Relays[i].relayPin, Relays[i].relayState?RELAY_ON:RELAY_OFF);
	gw.send(msg[i].set(Relays[i].relayState? true : false));
	gw.saveState( i, Relays[i].relayState );}                 // save sensor state in EEPROM (location == sensor number)
	
        Relays[i].oldValue = value;
        
	}
}

// process incoming message 
void incomingMessage(const MyMessage &message){
         
        if (message.type == V_LIGHT){ 
        if (message.sensor <noRelays){ 			  // check if message is valid for relays..... previous line  [[[ if (message.sensor <=noRelays){ ]]]
        Relays[message.sensor].relayState = message.getBool(); 
        digitalWrite(Relays[message.sensor].relayPin, Relays[message.sensor].relayState? RELAY_ON:RELAY_OFF); // and set relays accordingly
        gw.saveState( message.sensor, Relays[message.sensor].relayState ); // save sensor state in EEPROM (location == sensor number)
		}
	}
}

@jeylites

Just tested this sketch and it works. Thank for the effort.

[maglo18]

Could someone tell what i should to modify to use toggle button not flash button?

[jeylites]

@maglo18 what do you mean?

[maglo18]

In yours sketch state button should high next low then relay change state. I want to have possibility after button HIGH relay state change button LOW state relay change again

[jemish]

yes , I have same problem.

how can we use simple wall switch with relay to ON and OFF the lights.

[AWI]

For learning purposes: Instead of coding it for you, try the line of thought:

Now it changes with the toggle, so if "value" (switch) becomes high is changes the state of the relays, send the message to controller and stores it in EEPROM.

If you use a normal switch, you should change the state if when the "value" changes. So remember the last state of the switch and make it happen ;-)

btw :you need a variable to store the last button state and the physical position of the switch does not change if you update the relay switch from the controller..

[jeylites]

Just wondering any of you guys made progress in normal switch?

[rainair]

Hello this is my first post, but i follow my sensors for about 2 months.
Excuse my bad english.

For those how want use a normal in wall switch

just change the line:

if (value != Relays[i].oldValue && value == 0){

to

if (value != Relays[i].oldValue){

to

hope this was a bit helpfully

[jeylites]

@rainair, I tested it and it works! Thanks!!!

@jeylites said:

Relays[i].relayState = gw.loadState(i); // retrieve last values from EEPROM
digitalWrite(Relays[i].relayPin, Relays[i].relayState? RELAY_ON:RELAY_OFF); // and set relays accordingly
gw.send(msg[i].set(Relays[i].relayState? true : false)); // make controller aware of last status
gw.present(i, S_LIGHT); // present sensor to gateway
delay(250);

It's my idea, or shouldn't the sensor be presented to the gateway before sending it status?
Thanks! regards.

[jeylites]

@gonzalonal

I don't think it matters. You could try flip "gw.send & gw.present" and see how it respond to the change.

[ewgor]

Wow ! this is what i was looking for ... Could anyone please share with us some Openhab settings for this wonderful Arduino sketch?
How can we assign in OH buttons to correspond to the physical buttons on the breadboard ?

Looking for any answer.

Thanks all!
