Hi
I have trable to implement the mysensors lib i try programing DHT 22 on my mini but i cant
default sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

  metric = gw.getConfig().isMetric;
}

void loop()      
{  
  delay(dht.getMinimumSamplingPeriod());

  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();
  if (isnan(humidity)) {
      Serial.println("Failed reading humidity from DHT");
  } else if (humidity != lastHum) {
      lastHum = humidity;
      gw.send(msgHum.set(humidity, 1));
      Serial.print("H: ");
      Serial.println(humidity);
  }

  gw.sleep(SLEEP_TIME); //sleep a bit
}


But  i have problem to compilate

HumiditySensor:44: error: 'MyMessage' does not name a type
HumiditySensor:45: error: 'MyMessage' does not name a type

what i do wrong i add my sensors on MyDocuments/Arduino/libraries

ok but is no problem to connect wired sensors on gateway? did i need to cheange somethink on code?

im sorry :) for my google translator english

I have question can i mix wired connectrion sensors with wireless connectrion sensors to gateway

Hi

Im new here i have question about all system domoticz + arduino.

I want make this system on my home
but everything is done by wireless communication from here my question whether it is possible to combine domoticza with Arduino and rasppberry sleeps in a way wired and wireless ? the point is the part of Sensors will be connected directly to the gate
