DHT 22 error while updating #15847

besgum · 2018-08-05T15:27:28Z

Home Assistant release with the issue:
Version 0.75.1

Operating environment (Hass.io/Docker/Windows/etc.):

Raspberry pi 3b+, Hass.io supervisor 123

Description of problem:
DHT22 sensor is connected to the GPIO 18, 3.3V and ground. Home assistant cant update the sensor.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

sensor:
# DHT22 sensor
  - platform: dht
    sensor: DHT22
    pin: 18
    monitored_conditions:
    - temperature
    - humidity

Traceback (if applicable):

I have try with different DHT22 sensor, but the same happen

my config

sensor:

         - temperature
         - humidity

kaiomatico · 2018-08-21T14:19:49Z

So I took a look at the source code from adafruit DHT on github. The following code is used to determine the platform: https://github.com/adafruit/Adafruit_Python_DHT/blob/master/Adafruit_DHT/platform_detect.py from there have a look at def pi_version. Using cat /proc/cpuinfo the "Hardware" tab is being searched. Loging in via ssh to my hassIO on hassOS does not output the information this function is searching for. This is my output:

This is what it is searching for:
# Match a line like 'Hardware : BCM2709' match = re.search('^Hardware\s+:\s+(\w+)$', cpuinfo, flags=re.MULTILINE | re.IGNORECASE)

kaiomatico · 2018-08-21T14:21:07Z

If someone can tell me how to break out of the hassOS container and modify the file /usr/local/lib/python3.6/site-packages/Adafruit_DHT/common.py maybe we could easily fix it and push the changes to the adafruit github

kaiomatico · 2018-08-22T10:24:30Z

Just a quick update, I hope I don't spam too much: Moving my installation to hassbian makes the DHT Sensor work. So it is just a problem with hassIO / hassOS.

RssFra97 · 2018-08-22T10:49:59Z

ok, but none of the developers hear the problem or are they trying to fix it?

kaiomatico · 2018-08-22T11:02:51Z

@RWGaMeR I created an issue in the hassOS github repository but that got closed by the developer. Maybe it is not hassOS specific but hassIO specific. In the hassIO repository there is still an open issue about the DHT sensors, but they are trying to focus more on the build itself (using the correct pip and gcc versions). Here is the link, there has not been much activity in the last 2 weeks: home-assistant/supervisor#624

So because my issue was closed I guess the issue must be hassIO specific (not hassOS and not home-assistant specific and not Adafruit-DHT specific). So I don't know if they are trying to fix it.

RssFra97 · 2018-08-22T11:07:57Z

ok, thanks for info

RssFra97 · 2018-08-22T11:08:07Z

@kaiomatico

besgum · 2018-09-10T13:37:57Z

Hi, any news regarding this issue? it's been a month and I haven't been able to fix this. If someone could give me a hint to make the DHT22 component work again would be great

I have also the same problem in version 0.84.3 on an Raspberry Pi Zero w with a new installation of hassIO. The sensor is a DHT22.

I'm wondering because of the "cannot import name Rapsberry Pi_2_Driver"-> I'm using a Raspberry Pi Zero

Ahh, it is a bug in Adafruit_Python_DHT

The Pi Zero is not supportet yet.
