Problem implements MySensors lib



  • 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.

      // Send the Sketch Version Information to the Gateway

      // Register all sensors to gw (they will be created as child devices)
      gw.present(CHILD_ID_HUM, S_HUM);
      gw.present(CHILD_ID_TEMP, S_TEMP);
      
      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

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