@Jonae ok do flash again, do not do any apt commands. run my install script

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

So, i build my first module for MagicMirror: https://github.com/J0n4e/MMM-DHT22 hope it helps someone
