A very beginner needs help - MySensors and OpenHab !

[hek]

i cant believe that there are 1.7k users here, more than 1k online, more than 500 views (including mine (maybe half them :)) and nobody helps :eyes:

People might not have run into the same problems as you're having you know. And the amount of community members running OpenHab+MQTT isn't that huge I guess. So even if many here would like to help you we don't have the time or possibility to re-create your environment.

A good approach to isolate the problem (shaving off as much as much irrelevant stuff as possible). You know that the wireless communication is working... so something must be wrong in the rules or you've found some kind of bug in OpenHab.

You don't need CTs to test sending in a value from the Arduino.. Just set and send any value using the API to test it. Mocking is a good approach when testing.

@hek thanks for your replay! i'm not using OpenHab+MQTT but the serial gateway communication explained by @TimO and i got the errors shown above so my questions are point by point. i tried different ways to see if i can get loose of the errors but no chance and than i came here asking for help.
My idea was if somebody have the needed time to test my config (opehab + arduino) and to tell me if is working on their pc or not and maybe some instructions where or what needs to be changed, modified deleted or added.
I count on experienced people who can see quikly where is the mistake and who could give me useful information as for example @TimO did at one point.

Once again, besides hum and temp that works at this hour i need to add a few buttons who could turn a light on/of from openhab and from physiscal buttons too and to understand why if i add a new device as CT sensor its not displaying anymore the rest of the devices.
Thanks for understanding.

Hi @ewgor ,

could you make your whole configuration available for download? It is easier for us to help you to find the error.

[ewgor]

@TimO what do you mean by " configuration available for download"? i'm combining different Arduino sketches found here on the site and i'm trying to find a way to match them with the Openhab configuration found here too! All my files are above but right now i'm trying to combine the Arduino sketch from above with this one for relay with button actuator from here http://www.mysensors.org/build/relay and its very difficult. couldn't do it today, maybe tomorrow :(
As a conclusion because i don't know if i was very clear: Could anyone help me combine Arduino sketch from above with the one for relay with button actuator for 2 (two relays and two buttons) devices and to check the Openhab config which are above too? As i already said, today o tried all day long to combine them but cant lose the errors, it cant compile :(

Hoping for an answer ...

People, still struggling to get the relay with button actuator working with openhab!

The physical button is connected to digital pin 3 and a LED to digital pin 4.

but the LED is not switching on or off.
On the other hand when pressing the physical button on / off the LED is working but the switch in Openhab is not moving or refreshing.

i'm trying to take it easy! please help masters :)

Update:
i noticed that if i leave only the light Openhab config as bellow, when pressing the physical button on my breadboard it turns the led on or off and it changes the Openhab switch state from on to off and vice-versa but it doesn't work from Openhab to Arduino.

If i delete the rule "light" (the last part of rule file) the server doesn't show the error and the server still works so pressing the physical button it turns on or off the LED and it change the Openhab switch from on to off but from Openhab to Arduino, the same, still not communicating, not turning any LED!
This is how the server looks if i delete the rule "light" and i press the physical button on my breadboard:

This makes sens and the problem i know is on the rule file. Now is there anyone who can help me make this work from Openhab to Arduino too? thanks all for your kindness :)

PS: using the Arduino relay with button actuator sketch on which i added the node id 101 and the pins 48,49 for my Arduino mega.

[ewgor]

No body? Any idea?

[TimO]

Found it!

"received command" not "received update"!

rule "Light"
        when
                Item lightBar01 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

@TimO yuhuuuuuuu super! finally the damn led works ! thanks @TimO one small step for mankind but a huge step for me :)

[ewgor]

Hi,
@TimO finally I managed to add the dht 11 too and it works fine. Can you please tell me what to change in the rule file to add more buttons (same as this one that works)? I tried to change some parts of the light address but it doesn't work.
I would like to add a normal button too (not like a switch) with a door symbol like door open or close for my exit door and to change its status from blue to red when you push the button.

Thank you for the help you gave me by now!
All the best!

[ewgor]

Hi All,

Can anyone please tell me if I want to add a few more buttons (same as this one with relay with button actuator) what should i change in the Openhab rules and in the Arduino sketch too? can it be done as the relay actuator example ?

#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?

In the Openhab rules i tried to modify as i said above some of the addresses of the commands on or off from here:

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

except the last numbers which i understand are like 1 for ON and 0 for OFF but it didn't work.

The last thing that i would like to add is related only to Openhab if ill get an answer or a suggestion to my ask here above is a normal button (not like a slider) to control an electrical strike through a relay so when pressed once door open for 5 seconds or more and than close again. I know that here are more to discuss because maybe the door its not gonna be psychically closed but the Openhab status could show that the door is closed but this can be solved with a magnetic contact (i think) that can be added so the Openhab rules should be made like so: if the magnetic contact is connected than the door is closed and locked, else the door is open / unlocked even the electrical strike is closed until the magnetic contact will be connected! or to close the electrical strike only after the magnetic contact is closed.
OH too much talking, I know this is maybe too much for me but theoretical speaking I know how to make it and I think i know how to set up the connection but physically is impossible because of missing knowledge in programming Arduino or Openhab!

Lets take it one by one: Can anyone help me with first part of my request, how to add a few more buttons same as the only one working now?

Thanks all

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!

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:

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.
