Hello,
I have a weird issue with my two DHT22s: from time to time the data given is exactly twice as high as some seconds before:
dht22
I already tried different gpio pins, different DHT22s, tripple checked the wiring (the hardware should be ok).

Any ideas?
Thanks in advance!

I had the same problem just lately. It seems that a bit is incorrect, might be a timing issue. I implemented a completely different function to read the bits and better adjust to timing issues.
See my forked repo.
