      installed modules as described in read.me file but I get no reading of temp or hum.
      sensor is working, tested with AdaFruit example

      sudo ./AdafruitDHT.py 2302 27 (Data connected to gpio 27)
      I get a perfect temp & hum reading, so i’m shure sensor is working.
      i’m using an RPI3 - according to wiring pin, wpi 2 = gpio27 = physical pin 13.
      I think wiring is OK.

      only clock and this module installed.

        Hey guys :) Hope you are all good.
        Finally I have the time to work on this module again :)
        I had the same errors like you before and unsuprisingly did not found a solution for it.

        Is someone in this thread still active?

          @PaulB - glad you have found some time to work on it.
          Yes I still have the problem with reading the data in the MM.
          Hope you can find the cause. I would like to help you, but i’m not a programmer.
          The only thing I could help on is perhaps some beta testing.
          Cheers.
          Johan

            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?
