Right. Please replace the word temp with arr[1] and hum with arr[0] in line 33 in node_helper.js

Now my logs looks like this after I changed line 33:

Okay, so it definitely fails retrieving data from the sensor, but the error handling does not catch this failure.

I have test it with two dht22. One was mine and one I received from @Bangee who was so kind to test it before sending it and it was working at his home, but when I tried it at my home it wasn’t working. So I have no Idea what can be the failure.

Hi ,
so I just figure it out, that the motiondetector by alexyak blocking the DHT22 script. If I disable this module my DHT 22 works perfect. Somebody knows what make this problem?

that’s very strange!?!
Is this module working with a PIR Sensor or a Webcam?
Im using Paviro’s PIR Sensor to turn on an off my monitor.

With picamera. I installed MM on my other pi (completely new installation) and i got the same problem after i installed the motion detector. So I disabled on my MM the motion detector and it works fine on both pi’s. It’s very strange ;o(

I am using a PIR sensor.
So i can’t reproduce it.
