dht22 no reading from working sensor #3

Hello nebulx29,

Thanks for our work on connecting the dht22 to the pi. As the last piece of the puzzle for my magic mirror, I'm trying to connect a working dht22 to the magic mirror using your modules.

I hooked up the dht22 to my pi using through a breadboard, placing a 10k ohm resistor between the input and data line. The data line is linked to the GPIO.22 (= 22 using wPi, or 6 in BCM) on the pi and works perfectly using the Adafruit python package as I get consistent temp & humidity readings. screenshot:

I'v followed your read.me and didn't get any issues (cloning, installing prerequisites, installing, put into bin directory) so all seemed perfect.

However, once using the command to read from the bin (sudo ./dht22 c 22), it never returns any value and stays stuck as is:

I've tried re-installing multiple times and tried reading from all other pins (more by desperation than by logic..) but none of it worked.

Would you have any idea why? Is there any package that'd be missing from the read.me that could prevent the good reading using your dht22 package?

Thanks for the help :)

I'm having the same issue. Works fine with Adafruit. I'm on the latest WPi. Did anyone find a fix, workaround, another module to work with please?

Thank you in advanced!

Same issue for me. AdaFruit works perfectly but nothing with this module. Any chance of a response / update?

Hi all, for those of you who have the issue on using for a Magic Mirror, you can simply swipe to MMM-LocalTemperature which is working fine even if you have the issue listed here. Hope this helps!
