ECMD erstellen

[ahtdf]

Hallo kann mir da jemand helfen,
ich habe an einem Arduino_uno einen DHT12 Sensor den ich via USB mit Fhem auslesen möchte.
Da ich leider kein Perl programmieren kann , habe ich mir das aus diesem Wiki Beitrag(https://wiki.fhem.de/wiki/ECMD) herauskopiert.

Mein Arduino Sketch sieht so aus

• //2018.6.28
  #include <dht_nonblocking.h>
  #include <LiquidCrystal.h>
  LiquidCrystal lcd(12, 11, 5, 4, 3, 2 );
  
  #define DHT_SENSOR_TYPE DHT_TYPE_11
  //#define DHT_SENSOR_TYPE DHT_TYPE_21
  //#define DHT_SENSOR_TYPE DHT_TYPE_22
  
  static const int DHT_SENSOR_PIN = 8;
  DHT_nonblocking dht_sensor( DHT_SENSOR_PIN, DHT_SENSOR_TYPE );
  
  void setup( ){
  lcd.begin (16, 2);
  
    Serial.begin( 9600);
  }
  void loop( )
  {
    float temperature;
    float humidity;
  
    if(dht_sensor.measure(&temperature, &humidity)){
      Serial.print("1234 ");
      Serial.print( "T" );
      Serial.print(temperature);
      Serial.print( "°C " );
      Serial.print( "H" );
      Serial.print(humidity);
      Serial.println( "%RH" );
      delay (5000);
       lcd. clear ();
        lcd. setCursor(0, 0);
        lcd. print ("Temperatur=");
        lcd. print (temperature, 1 );
        lcd. print ( "C" );
        lcd. setCursor(0, 1);
        lcd. print ("Feuchte = ");
        lcd. print (humidity, 1 );
        lcd. print ( " %," );
    }
  }

Und das ist meine classdev

• params devId1234
  reading temperature match "%devId[^\n]+\n"
  reading temperature postproc { /%devId[^T]+T([-+.,0-9]+).*/; $1 }
  reading humidity match "%devId[^\n]+\n"
  reading humidity postproc { /%devId[^H]+H([-+.,0-9]+).*/; $1 }
  state humidity

Raw Definition

• defmod Arduino_DHT12 ECMD serial /dev/ttyACM1@9600
  attr Arduino_DHT12 classdefs DHT12=opt/fhem/DHT12.classdef
  attr Arduino_DHT12 partial 200
  attr Arduino_DHT12 room Arduino
  attr Arduino_DHT12 split \r\n
  attr Arduino_DHT12 verbose 5
  
  setstate Arduino_DHT12 opened
  setstate Arduino_DHT12 2021-05-24 13:38:22 state opened
  
  

Und im Eventmonitor
steht ab und an
2021-05-24 13:44:34 ECMD Arduino_DHT12 UNKNOWNCODE   

Kann mir da jemand weiterhelfen?
