    Hey

    I have a problem with my sketch.
    It is a relay with battery.

    When i turns ON the relay on vera nothing happens and so on.
    But the vera send command when i toggle it.
    Sometimes it have problems with sending the command from vera

    #include <MyTransportRFM69.h>

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

    // Construct MySensors library
    MySensor gw(radio, hw);
    
    unsigned long SLEEP_TIME = 900000;  // sleep time between reads (seconds * 1000 milliseconds)
    int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
    int oldBatteryPcnt = 0;
    
    void setup()  
    {
      // use the 1.1 V internal reference
      #if defined(__AVR_ATmega2560__)
      analogReference(INTERNAL1V1);

      // Initialize library and add callback for incoming messages
      gw.begin(incomingMessage, AUTO, true);
      // Send the sketch version information to the gateway and Controller
      gw.sendSketchInfo("Relay", "1.0");
    
      // Fetch relay status
      for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
        // Register all sensors to gw (they will be created as child devices)
        gw.present(sensor, S_LIGHT);
        // Then set relay pins in output mode
        pinMode(pin, OUTPUT);

      }
      
    }
    
    
    void loop()

       Serial.print("Battery Voltage: ");
       Serial.print(batteryV);
       Serial.println(" V");
    
       Serial.print("Battery percent: ");
       Serial.print(batteryPcnt);
       Serial.println(" %");
       #endif
    
       if (oldBatteryPcnt != batteryPcnt) {
         // Power up radio after sleep
         gw.sendBatteryLevel(batteryPcnt);
         oldBatteryPcnt = batteryPcnt;
       }
       gw.sleep(SLEEP_TIME); 
    }
    
    void incomingMessage(const MyMessage &message) {
      // We only expect one type of message from controller. But we better check anyway.
      if (message.type==V_LIGHT) {
         // Change relay state
         digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
         // Store state in eeprom
         gw.saveState(message.sensor, message.getBool());
         // Write some debug info
         Serial.print("Incoming change for sensor:");
         Serial.print(message.sensor);
         Serial.print(", New status: ");
         Serial.println(message.getBool());
       }
       
    }
    

    Can anyone help.

    /Nikolaj

      I don't think you can do gw.sleep. gw.sleep turns the radio off, so the sensor wouldn't receive the command from your controller.

        Of course i delete the line gw.sleep(SLEEP_TIME);
