No reading from DHT sensor

Re: MMM-DHT22 Humidity and Temperature Module
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.
anybody can help solving this.
thx - sudo ./AdafruitDHT.py 2302 27 (Data connected to gpio 27)

nobody to help?

Why aren’t you asking in the forum post for the module?

@cowboysdude
I did, but got message that topic where old and that is was better to create new topic - so i did.
anyhow i’ll post it there as well -
@Johans Ok when you start MM what does the developers window say? Any errors?
-
@cowboysdude
nothing, all is perfect - no errors.yesterday tried every pin, nothing happens.
Only module clock & this DHT22 module are in my config.
Remover & reinstalled module.
No luck .
I thought sensor might be defect but I get a reading of temp & hum via the Adafruit DHT test program.
I’ve seen other people have same problem - no reading. I’m wondering if they have sorted out or just gave up on this module. -
@Johans No sure… I don’t have a sensor or I’d be happy to test it out …
