Hello all i made a mysensors sketch with a DHT sensor and a relay in one node with 3 child devices.
#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>
#define NODE_ID 5 // ID of node
//child ids

//relay state

#define NUMBER_OF_RELAYS 1
//sleep timer settings
unsigned long SLEEP_TIME = 1000; // Sleep time var, first read is 0
unsigned long SLEEP_TIME_POST = 60000; // Sleep time var changes to this value after
unsigned long LAST_SLEEP_TIME = millis(); // Sleep time between reads (in milliseconds)
bool state;
//mysensors setup
MySensor gw;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);

digitalWrite(RELAY_PIN0, RELAY_OFF);
// Then set relay pins in output mode
pinMode(RELAY_PIN0, OUTPUT);
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);
// mysensor startup and Send the Sketch Version Information to the Gateway
gw.begin(incomingMessage, AUTO, true);
gw.sendSketchInfo("DHT&relay&button", "1.1");
// Register all sensors to gw (they will be created as child devices)

// Set relay to last known state (using eeprom storage)

digitalWrite(RELAY_PIN0, state?RELAY_ON:RELAY_OFF);
}
void loop()
{
if (millis() - LAST_SLEEP_TIME > SLEEP_TIME) {
dhtupdate();

}
}
gw.process();
}

// Change relay state

// Store state in eeprom
gw.saveState(message.sensor, message.getBool());
// Write some debug info
Serial.print("Incoming change for relay1 sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
}
}
}
void dhtupdate() {
float temperature = dht.getTemperature();
if (isnan(temperature)) {
Serial.println("Failed reading temperature from DHT");
} else if (temperature != lastTemp) {
lastTemp = temperature;
if (!metric) {
temperature = dht.toFahrenheit(temperature);
}
gw.send(msgTemp.set(temperature, 1));
Serial.print("T: ");
Serial.println(temperature);
}
float humidity = dht.getHumidity();

Serial.println(humidity);
}
}
WHen i upload the sketch i cannot discover device but i do see output in debug. in debug i see the following.

does somebody has an idea?
