      @lif It’s requiring tools no longer available, so dead module. Use something else.

      https://github.com/Tom-Hirschberger/MMM-Temperature is what I used when I had a module hooked up to it.

      Thanks, I’ve given it a try but get an error in the last stage of the installation

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

        @lif I’m not sure on that, @wishmaster270 (Tom) would know more.

        The "E" in "Javascript" stands for "Easy"

            @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.

                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:

                    @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
