    Hey, i have the same problem.
    With “./Adafruit_Python_DHT/examples/AdafruitDHT.py 22 27” comes the Temperatur “Temp=20.1* Humidity=29.3%”
    The DHT22 is Pinned on PIN 13 (27) (WiringPi 2). On the Mirror is the Temperatur and the Humidity undefined.
    Whats the Problem? I found nothing…

      @DocVooDoo Then I don’t know, maybe there is something wrong with the module…

      Have you tried mine? https://github.com/ryck/MMM-DHT-Sensor

          @DocVooDoo sometimes the raspberry pi needs some time to pick up the values… try to increase the update time (ie, 30 seconds) and wait for it to update a couple of times…

            @ryck nothing has changed. i have “node serveronly” running, and the log says “Error: failed to read sensor at Error (native)”
            but the sensor works… look

              @DocVooDoo Weird… did you follow all the instructions? ie, install bcm2835, npm install, etc?

                      @DocVooDoo well, no idea then… Have you tried to run the normal version (instead of the serveronly)?
