      @lif Hi. Great you want to try one of my modules.

      Can you try installing a additional python system package with

      sudo apt install python3-rpi-lgpio
      

      I tried the scripts on my newly installed system with Bookworm and everything worked as expected.
      Maybe the missing package had been installed with something else I installed on my system.

      Thanks, that was already installed

      sudo apt install python3-rpi-lgpio
      Reading package lists... Done
      Building dependency tree... Done
      Reading state information... Done
      python3-rpi-lgpio is already the newest version (0.6-0~rpt1).
      0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
      
      

      This is on Bookworm

        That’s strange…Can you try to start with a new, fresh virtual python environment and install the needed libs again?

        Remove old virtual environment:

        rm -rf /home/pi/MagicMirror/modules/MMM-Temperature/scripts/py-venv
        

        Install the needed system libs:

        sudo apt -y update && sudo apt -y install python3-venv libgpiod2
        

        Re-Create the virtual environment:

        cd ~/MagicMirror/modules/MMM-Temperature/scripts
        ./venvWrapper.py --verbose --venv-name py-venv --create
        

        Re-Install the libs:

        cd ~/MagicMirror/modules/MMM-Temperature/scripts
        ./venvWrapper.py --venv-name py-venv --install-libs adafruit-circuitpython-dht
        

        Run the test again:

        cd ~/MagicMirror/modules/MMM-Temperature/scripts
        ./venvWrapper.py --venv-name py-venv --run ./dht22
        

        If it fails again. Can you please provide the output of

        cd ~/MagicMirror/modules/MMM-Temperature/scripts
        source py-venv/bin/activate
        pip freeze
        deactivate
        

        The output should look something like:

        Adafruit-Blinka==8.66.1
        Adafruit-Blinka-Raspberry-Pi5-Neopixel==1.0.0rc2
        adafruit-circuitpython-busdevice==5.2.13

          @wishmaster270 AND you must enable the virtual env in the script if pm2 starts MagicMirror

            @sdetweil Hi sam. My wrapper script will use the python binary in the virtual environment folder. This way the environment will be activated automatically.

                The only difference from yours is mine is missing the second line.

                Hope this helps

                  Hi,

                  I’ve gone through your procedure again and this time it works.

                  The only difference is that I run a python3 script to control screen blanking using a PIR before starting Magic Mirror, this time I didn’t start that script.

                  With the PIR script and MagicMirror running I get:

                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 23.5, "humidity": 53.7, "temperature_f": 74.30000000000001, "error": false}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 23.5, "humidity": 53.7, "temperature_f": 74.30000000000001, "error": false}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 0.0, "humidity": 0.0, "temperature_f": 32.0, "error": true}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 23.6, "humidity": 53.5, "temperature_f": 74.48, "error": false}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 0.0, "humidity": 0.0, "temperature_f": 32.0, "error": true}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 23.7, "humidity": 53.3, "temperature_f": 74.66, "error": false}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ ./venvWrapper.py --venv-name py-venv --run ./dht22
                  {"temperature_c": 23.8, "humidity": 53.2, "temperature_f": 74.84, "error": false}
                  pi@mm:~/MagicMirror/modules/MMM-Temperature/scripts $ 
                  
                  

                  I can live with that.

                  Thanks for all your help
