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

Same failure on install.

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

Hope this helps

@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

This is on Bookworm

Thanks, not the end of the world if I can’t use it.

@BKeyport said in MMM-DHT22:

@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

I have installed the module but get the following when I try to run your test ‘python3 AdafruitDHT.py 22 26’

I know the DHT-22 works on GPIO pin 26

Any thoughts?

Bonjour,
J’aime bien l’application mais alors qu’elle se met à jour selon le texte, le graphique ne se met pas à jour.

Je suis anglais, puis-je changer vos chaînes de test en anglais ou cela affectera-t-il le fonctionnement de l’application ?

@FrostByte
I don’t know if it helps but the only way I could get my old DVI input monitor to turn on & off was with Wayland enabled and the commands

DISPLAY=:0.0 xrandr --output HDMI-1 --auto --rotate left
and
DISPLAY=:0.0 xrandr --output HDMI-1 --off

@lif said in "Invalid Date" appears in Weather module. MM v2.29.0:

> I have tried adding the apiVersion: '2.5'

each of those lines had trailing commas, right?

Not that line but that wasn’t the problem :-)

Thanks for the link showing how to subscribe to OpenWeathermap which solved the problem.

@sdetweil

I’ve reinstalled MagicMirror with your script, it worked wonderfully, than you very much for doing this.

Best regards from France.
