DHT22 with Debian 12 Bookworm

[wishmaster270]

Hi,

I do not use a DHT11 at the moment but my MMM-Temperature should still work

https://github.com/Tom-Hirschberger/MMM-Temperature

Just checked the install process on a Debian Bookworm and it works fine.

hello @wishmaster270 , Ok, thanks, I will try!

hello @wishmaster270 ,
I could install and try your module.
The result is empty :

When I test it direct through the terminal as you describe in you module description, “error” is on “true”.

But, interesting, it finally works when I try another direct way as described on https://pimylifeup.com/raspberry-pi-humidity-sensor-dht22/, so that it seems, that everything should work.
.

Now, do you think that there suddenly could be an error in your module ?

Sorry for disturbing you with this kind of problem, but thank you anyway in advance if you can help me :-)

There are at least four modules on the list dealing with the DHT-22. J0n4e
MMM-DHT22, ckoutavas MMM-DHT, cslev MMM-loldht22. Just do a search for dht and they will pop up.

Good luck

@RonR thanks!

Hi. No problem. If I have time it try to help.

It looks like there will installed two additional python libs in the venv in the tutorial you shared.
Maybe one of the libs is missing in the virtual environment my script creates.

You can add them to the venv with:

cd ~/MagicMirror/modules/MMM-Temperature/scripts
./venvWrapper.py --venv-name py-venv --install-libs lgpio RPi.GPIO

If you change line 25 in my dht11 script from except: to finally: you should see the whole error.

But make sure to revert the change after the problem is fixed.

@wishmaster270 thanks, I will try this week-end and inform you. Could interest the other users.

@wishmaster270 I think the gpio setup changed in bookworm
