Hello Guys,

i try to do some Controldevices for Homeautomation. My purpose is an self-sufficient system which is controlable from a mysensor.
So i use some Relays from Eltako - the ES12Z-200-UC Type.
Here is the Datasheet: http://www.eltako.com/fileadmin/downloads/en/_datasheets/Datasheet_ES12Z-200-UC.pdf

The big benefit is the standalone working and the simple controlability. So now i have done a MySensor Box and atached it on the control on and off connection and also a senseloop over the second switch contact to detect the State.
I adapt the Relay Sketch and include the Sensor in my FHEM Network. Now my Problem: When i detect a one, i send it to FHEM and FHEM reply it to me and so i switch again.. how can i interlock this?

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

#define PIN_LEDRD  8
#define PIN_LEDGN  7
#define PIN_SWON   5
#define PIN_SWOFF  6
#define PIN_STATE  4
#define CHILD_ID 1   // Id of the sensor child
#define RELAY_ON 1
#define RELAY_OFF 0

Bounce debouncer = Bounce();
int oldValue = 0;
bool state;
MySensor gw;
MyMessage msg(CHILD_ID, V_LIGHT);

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(PIN_STATE, INPUT);
  // Activate internal pull-up
  digitalWrite(PIN_STATE, HIGH);

  // After setting up the button, setup debouncer
  debouncer.attach(PIN_STATE);
  debouncer.interval(5);

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

  // Make sure relays are off when starting up
  digitalWrite(PIN_SWON, 0);
  digitalWrite(PIN_SWOFF, 0);
  digitalWrite(PIN_LEDGN, 1);
  digitalWrite(PIN_LEDRD, 1);
  // Then set relay pins in output mode
  pinMode(PIN_SWOFF, OUTPUT);
  pinMode(PIN_SWON, OUTPUT);
  pinMode(PIN_LEDGN, OUTPUT);
  pinMode(PIN_LEDRD, OUTPUT);

  // Set relay to last known state (using eeprom storage)
  state = gw.loadState(CHILD_ID);
  //digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
}


/*
   Example on how to asynchronously check for new messages from gw
*/
void loop()
{
  gw.process();
  debouncer.update();
  // Get the update value
  int value = debouncer.read();


  if (value != oldValue ) {
    Serial.print("Incoming change for value:");
    Serial.println(value);

    if (value == 1) {
      digitalWrite(PIN_LEDRD, 0);
      digitalWrite(PIN_LEDGN, 1);
    } else {
      digitalWrite(PIN_LEDRD, 1);
      digitalWrite(PIN_LEDGN, 0);

    }

   // gw.send(msg.set(value), true); // Send new state and request ack back
  }
  oldValue = value;
}

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 (state == 1) {
      digitalWrite(PIN_SWON, 1);
      //digitalWrite(PIN_LEDRD, 1);
      delay(100);
      digitalWrite(PIN_SWON, 0);
      // digitalWrite(PIN_LEDGN, 0);
    } else {
      digitalWrite(PIN_SWOFF, 1);
      delay(100);
      digitalWrite(PIN_SWOFF, 0);
      // digitalWrite(PIN_LEDRD, 0);
      // digitalWrite(PIN_LEDGN, 1);

    }

    // Store state in eeprom
    gw.saveState(CHILD_ID, state);

    // Write some debug info
    Serial.print("Incoming change for sensor:");
    Serial.print(message.sensor);
    Serial.print(", New status: ");
    Serial.println(message.getBool());
  }
}

Can you help me a little bit?
