A very beginner needs help - MySensors and OpenHab !

ewgor

People i see that this post was seen by more than 2k times but nobody is answering! How is this possible? Nobody knows how to do it or everybody enjoy watching a noob asking for help? Common people at least off topic let's say hi each other!

hek

Hey @ewgor, tone it down a bit. You won't get any answers by acting aggressive.

It could be as simple as no-one has the the answer and you got to find a solution yourself.

ewgor

@hek thanks for the answer. At least now i know i'm not alone :). Anyhow as far as i've seen by now only @TimO was the only one who answered me and gave me some info. It is possible that non of the heros, admins or other kind of this forum members to have a suggestion for me?
Sorry if i was aggressive again!

Good help :)

@ewgor said:

#define RELAY_1  3  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)

i mean first relay is connected to pin 3 and the next relay to pin 3+1=4, pin 4+1=5 and so on and the buttons pins to be alocated in the same way? is there any way to do it like this but for the relay with button actuator example?

Well, the short answer for this is yes. It depends on your sketch. The loop with pin+1 is just a short notation.

I would suggest to start with the simple sketch with one button here: http://www.mysensors.org/build/binary

Give the node a static id, change items, rules and sitemap in OH.

You have to change V_TRIPPED to V_LIGHT:

// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID,V_TRIPPED);

So the OH rule with V_LIGHT will match and the item state is changed, when the button is pressed.

ewgor

Oh TimO i thought i'll never see you again here :) thanks for the answer.
I'm using the RelayWithButtonActuator example on which i added the humidity and temperature part and its working well. I choose this example because in this way i can get in real time the light status in Openhab even the light is turned ON / OFF from physical button on the breadboard or from the Openhab button.
The Openhab rules are already made with the V_LIGHT command not the V_TRIPPED.

I cant figure out what to add in the Arduino sketch to add more relays and more buttons and to make it work in the setup or loop functions. Than, on the Openhab rules i tried to copy the only light rule i have right now and to change some of the numbers in the

sendCommand(Arduino, "101;1;1;0;2;1\n")

but its not working :(

If i'll get at least 5 buttons and 5 relays working in this way it would be perfect.

Looking for any answer.

ewgor

Hello? TimO? :) are you there?

TimO

Well, there are many approaches and I would go the easiest (but not the most elegant) way.

Double everything for every additional button / relay. If that works for two/three buttons/relays use arrays (like in the relay example sketch).

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

#define RELAY_PIN  4  // Arduino Digital I/O pin number for relay 
#define RELAY_PIN2 5 ######## ADD THAT ######
#define BUTTON_PIN  3  // Arduino Digital I/O pin number for button 
#define BUTTON_PIN2 6 ######## ADD THAT ######
#define CHILD_ID 1   // Id of the sensor child
#define CHILD_ID2 2 ######## ADD THAT ######
#define RELAY_ON 1
#define RELAY_OFF 0

Bounce debouncer = Bounce(); 
Bounce debouncer2 = Bounce(); ######## ADD THAT ######
int oldValue=0;
int oldValue2=0; ######## ADD THAT ######
bool state;
bool state2; ######## ADD THAT ######
MySensor gw;
MyMessage msg(CHILD_ID,V_LIGHT);
MyMessage msg2(CHILD_ID2,V_LIGHT); ######## ADD THAT ######

void setup()  
{  
  gw.begin(incomingMessage, AUTO, true);

  // Send the sketch version information to the gateway and Controller
  gw.sendSketchInfo("Relay & Button", "1.0");

 // Setup the button
  pinMode(BUTTON_PIN,INPUT);
  pinMode(BUTTON_PIN2,INPUT); ######## ADD THAT ######
  // Activate internal pull-up
  digitalWrite(BUTTON_PIN,HIGH);
  digitalWrite(BUTTON_PIN2,HIGH); ######## ADD THAT ######
  
  // After setting up the button, setup debouncer
  debouncer.attach(BUTTON_PIN);
  debouncer2.attach(BUTTON_PIN2); ######## ADD THAT ######
  debouncer.interval(5);
  debounder2.interval(5);######## ADD THAT ######

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID, S_LIGHT);
  gw.present(CHILD_ID2,S_LIGHT);######## ADD THAT ######

  // Make sure relays are off when starting up
  digitalWrite(RELAY_PIN, RELAY_OFF);
  digitalWrite(RELAY_PIN2,RELAY_OFF); ######## ADD THAT ######
  // Then set relay pins in output mode
  pinMode(RELAY_PIN, OUTPUT);
  pinMode(RELAY_PIN2, OUTPUT); ######## ADD THAT ######   
      
  // Set relay to last known state (using eeprom storage) 
  state = gw.loadState(CHILD_ID);
  state2 = gw.loadState(CHILD_ID2); ######## ADD THAT ######
  digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
  digitalWrite(RELAY_PIN2, state2?RELAY_ON:RELAY_OFF); ######## ADD THAT ######
}


/*
*  Example on how to asynchronously check for new messages from gw
*/
void loop() 
{
  gw.process();
  debouncer.update();
  debounder2.update(); ######## ADD THAT ######

  // Get the update value
  int value = debouncer.read();
  if (value != oldValue && value==0) {
      gw.send(msg.set(state?false:true), true); // Send new state and request ack back
  }
  oldValue = value;
} 

value = debouncer2.read(); ######## ADD THAT ######
  if (value != oldValue2 && value==0) { ######## ADD THAT ######
      gw.send(msg2.set(state?false:true), true); // Send new state and request ack back ######## ADD THAT ######
  } ######## ADD THAT ######
  oldValue2 = value; ######## ADD THAT ######
} ######## ADD THAT ######
 
void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.isAck()) {
     Serial.println("This is an ack from gateway");
  }

  if (message.type == V_LIGHT) {
     // Change relay state
     state = message.getBool();
     if(message.sensor == 1) { ######## ADD THAT ######
       digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
       // Store state in eeprom
       gw.saveState(CHILD_ID, state);
     } else if(message.sensor == 2) { ######## ADD THAT ######
       digitalWrite(RELAY_PIN2, state?RELAY_ON:RELAY_OFF); ######## ADD THAT ######
       // Store state in eeprom ######## ADD THAT ######
       gw.saveState(CHILD_ID2, state); ######## ADD THAT ######
    }
    
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());
   } 
}

The code is not tested nor compiled, but I hope you'll get the idea of how to add a button and a relay.

Of course this could be done much more elegant with arrays, that could be your next step.

Wow! thanks for your time to fill this sketch! appreciate that.

I tried your sketch and after cleaning some small mistakes i got these errors and i don't know how to lose them.

and those are the errors:


sketch_sep09a.ino:81:3: error: expected unqualified-id before 'if'
sketch_sep09a.ino:84:3: error: 'oldValue2' does not name a type
sketch_sep09a.ino:85:1: error: expected declaration before '}' token
Error compiling.

About the OH rules i made them like this:

rule "Light"
        when
                Item lightBar02 received command
        then
               if(receivedCommand == ON) {
            sendCommand(Arduino, "101;1;1;0;2;1\n")
        }
        if(receivedCommand == OFF) {
           sendCommand(Arduino, "101;1;1;0;2;0\n")
        }
end

what do you think? do i still need to modify something?

Thank you a lot!:pray:

TimO

There is a copy & paste error. Remove the bracket after "oldValue = value;" :)

The OH rule looks good.

ewgor

@TimO still doesnt want to compile :(
this is the last error:

sketch_sep10b.ino:81:3: error: expected unqualified-id before 'if'
Error compiling.

Thanks!

You have a closing bracelet ({) too much that's ending your loop() method. I corrected it and added a comment so you can see what's been causing the problem.

b.t.w. I have no knowledge of openHab.

@TheoL thanks man, I'll try it right now, thanks again.

Guys, i tried this sketch above and now it can be uploaded but its not working well.
The system reacts like this: the first button ( old one) turns the led on / off on the breadboard but its not refreshing the OH button on the webpage and i get some i get some WARN on the server like this:

I don't understand why i get so many things on the server pressing once on and once off!
The second button is completely dead, it doesn't do anything on the breadboard or on the web.
I think the Arduino sketch has some bugs somewhere even it can be compiled. Maybe something inside is wrong or maybe this is not the right way to multiply relays and buttons.

Any suggestion will be kindly appreciated.
Thanks!

PS: I forgot to say that i added in the Arduino sketch the address of the node point:

#define NODE_ID 101

Hey guys, i found the solution here array-relay-button-actuator but now the OH part comes 'couse this is different solution. How can i add CHILD_ ID's in this case to create more buttons in OH? i mean how to make difference between the two relays in OH?

Can somebody please help me? This is what i was looking for.

Thanks :scream:

I see, i need to search for help on another forum ...
Many thanks to TimO who helped me a lot.

Hello @ewgor, I follow you on another forum about this subject and are interested myself of this system. I found in the code you posted a small error - might this to be the problem.
Please let me your email address - I would like to talk about this topic

@ewgor said: Rules:

var HashMap<String, String> sensorToItemsMap = newLinkedHashMap(
"101;1;" -> "lightBar01", // looks good
"lightBar01" -> "101;1;",
"101;2;" -> "lightBar01", // <<<<<--------------------------HERE----------------:)
"lightBar02" -> "101;2;"
)

A very beginner needs help - MySensors and OpenHab !
