      @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.

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

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

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

              @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

                  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.
