MMM-DHT-Sensor stopped working
-
Hi all,
i have this module installed:
https://github.com/ryck/MMM-DHT-Sensor/
it worked fine for several years now.
However i had to update/upgrade my Raspi 3 because other modules stopped working and now this module does not work anymore.
I tried to reinsall the module and bcm2835 but it didnt help.
Since i can readout the DHT with a python script i assume the sensor is still working. I also didnt change the (working) config so i guess the pin should be fine (GPIO6). I dont know what to do now. Does someone have a similar problem?
Thanks and cheers!

@Dracarys did you redo this step in the module install
https://github.com/ryck/MMM-DHT-Sensor/#bcm2835 -
Yes i also tried that.
-
@Dracarys What is Update/Upgrade?
Just sudo apt update the then sudo apt full-upgrade or something different? Seems odd that other modules stopped working, you updated Pi OS, I assume and now DHT sensor quits.
What is status of the other modules that were broken that prompted an update. -
@ankonaskiff17 just run my script for upgrade…
-
@sdetweil I was mainly curious to understand how it broke.
I look at these MM’s as these totally encapsulated hardware/module systems where say you built one two years ago, used whatever rendition of Pi+MM+modules were out at the time. You plugged it in and off to the races.IF you leave it alone, don’t update Pi, don’t update MM, it should run forever (technically) until something in the hardware breaks.
So I’m always intrigued as a learning thing for me is just to understand what were the circumstances around “It has run for years and It just quit working”
-
@ankonaskiff17 ok. I understand your approach
-
@sdetweil Now if I had a magic wand I could wave and this ALT issue would go up in a puff of smoke that would be nice too.
-
@ankonaskiff17 never ever tried it. the official keystroke is alt and spacebar
-
@sdetweil This is where ALT comes from. First one I built I did on my own with no guidance and I expect it is why you have seen other people saying ALT doesn’t work anymore. I can only work off the documentation. Documents said hit ALT key, I hit ALT key and it works.
