RE: MMM-DHT22 Humidity and Temperature Module
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.

Big problem with CPU load
Hi Folks!
My CPU last is extremely high. For quite some time. I made a screenshot. What exactly can that be? Have the system newly installed completely.
I will continue to observe this.
Greetings, Marcel
