I fixed the "no module found" error by running "sudo apt install python3-rpi.gpio". However the sensor still doesn't work, I now get "DHT sensor not found, check wiring" from the adafruit test script.
The sensor is connected to GPIO4 (pin 7). Inside the script I have:
dhtDevice = adafruit_dht.DHT22(board.D4)
and have also tried:
dhtDevice = adafruit_dht.DHT22(board.D4, use_pulseio=False)
Have got it working.
After finding this, I installed the following:
pip3 install sysv-ipc
And now the sensor is working fine in both octoprint and the test script.
I still require "use SUDO" to be disabled under advanced settings like I did with the 3B+. Which makes sense because if a run the test script as sudo it still says sensor not found.
i had this issue but manged to get rounf that im using the dht11 sensor and its reading temp and humi but to dislaying the values on my octoprint
Hey guys, I've recently changed from using a pi 3b+ to a pi 4b. I previously had a DHT22 temp sensor working with the enclosure plugin on the 3B+. Its now connected the same (to GPIO 4) on the 4B but I cannot get it to work.
