Please check this comment.
I have observed some random “Failed to read from DHT sensor” errors, that have been resolved with this bugfix provided by W-E
Good luck.

- Wed Jan 20, 2016 3:58 pm #39315 I always thought these things were flakey until I wrote my own non polling C diver from scratch for the ESP. Suffice to say, I have had one running for few months non stop, 24x7. Looking at the data, as far as I can see it has never missed a beat. You will probably find, if the driver is working, they work perfectly.
(Doing the timing in an interrupt was really interesting. There are differently timed pulses at the word boundaries of the data. Even though this is not documented in the specs and I don't need to use them, they appear in sensors from 3 different vendors.)

Did you manage to solve the error? I have the same issue i believe =/

Have not tried any of links previously posted, that is a task for tomorrow.
