I have a major problem with the DHT22, the sensor is shown as unkonwn in pimatic!
The BCM2835 library v1.5 is installed as well as the wiringPi and the pimatic-dht22-sensors plugin. I used a Raspberry Pi 3 B.
It´s possible to get the data with loldht and the values are comprehensible.
I´m the Raspbian build 2016-09-23 and a DHT22 module with pre-installed resistors.
But all data I got in pimatic is UNKNOWN at Humidity and Temperature!
I have installed the whole system 2 times to avoid installation failures depending on the installation order from the plugins and the library.
The system is for a temeperature control from a terrarium and should work with 2 DHT22
and a USB controlled 230VAC socket strip.
I hope for some quick suggestions or a tutorial for my special case.
