Please merge this and create a new release. Thanks.

[brennen]

Tested, seems to be working fine. Release incoming.

Hi, thanks for this fix. Any idea when this will be available in hass.io?

[fabaff]

After @brennen created a new release that is available at PyPI.

[langestefan]

Nice. Any update @brennen ? Still getting the error in hass.io.

[geofbaum]

@langestefan The latest update to PyPi was on the 7th of November. Not sure why you're getting an error if Hass.io and your setup are using the updated code.

[langestefan]

@geofbaum Also not sure. Error is still exactly the same so I'm guessing this fix hasn't been included in the most recent release.

[brennen]

The changes in this PR are included in version 1.4.0, uploaded to PyPI (for both the Adafruit_Python_DHT and Adafruit-DHT variants) of the library on the 7th.

That said, having glanced over the issue on home-assistant, I'm not sure whether this would be a fix or not. I'm not familiar with hass.io and haven't tried to test platform detection there.

I have not investigated deeply, but it looks like home-assistant is pinning the library to an earlier release.

(Failing that, it's possible to override the platform and skip platform detection when calling read() or read_retry(). That might be of use but I'm really not familiar with the context this is being used in.)

I've tried this but I couldn't locate the file raising the error:
File "/usr/local/lib/python3.6/site-packages/Adafruit_DHT/common.py"

Seems there is no folder 'Adafruit_DHT' in my hass.io instance.

Yes, we are pinning the releases. 1.4.0 will be available in the upcoming 0.84 as for 0.83 it was too late.
