Temperature/Humidity Sensor Setup Issue

What is the problem?

I am trying to wire a DHT11 temperature/humidity sensor to interface with the enclosure plugin. I am following this walk through https://awesomeopensource.com/project/vitormhenrique/OctoPrint-Enclosure and have run into an issue installing the packages need. This is the terminal inputs which have been used.

cd ~
git clone https:// github.com/adafruit/Adafruit_Python_DHT .git (remove the spaces. put there to remove hyperlink)
cd Adafruit_Python_DHT
sudo apt-get update
sudo apt-get install build-essential python-dev python-openssl
sudo python setup.py install

All scripts run expect "sudo python setup.py install". At this step I receive this error:

Traceback (most recent call last):
File "setup.py", line 1, in
from setuptools import setup, find_packages, Extension
ImportError: No module named setuptools

What did you already try to solve it?

I have tried testing the file path which appears to be valid. I have restarted the process of installing the packages. I have rebooted the system.

Have you tried running in safe mode?


Did running in safe mode solve the problem?

Hello @matt !

The driver that is mantioned in the instructions is deprecated:

You may use the new one:

It should be supported by my plugin:

It should be pretty easy to wire up. My plugin should auto detect it.

I followed that tutorial and I am still unable to get values through OctoPrint Enclosure Plugin or terminal. The libraries/packages installed without error. The sensor has a led which is on so the unit is receiving power and ground. In respect to plugin setup, do I specify the physical PIN number or the GPIO PIN number? The plugin dose not specify. I have tried both without success.

Have you tried to run the test ( python3 dht_simpletest.py) that is mentioned in the second half on the site (Python Setup | DHT Humidity Sensing on Raspberry Pi or Beaglebone Black with GDocs Logging | Adafruit Learning System) ?

In the Top Temp plugin, I cannot find an option to accept data from a GPIO pin. Can you point me in that direction?

In top temp, you have to all a python command script to get the values:

Ahh if you were using an DS18B20 it would autodetect them and show under predefined. I will have to try and setup a DHT11 later today. I would highly recommend a DS18B20 - they are a lot more rpi friendly and supported directly in the hardware.

Hi There. I case of a not well working Enclosure Pluginat the moment i found my own solution working with a DHT22 and the TopTemp Plugin. Thank you for this great job .

I just modified AdafruitDHT.py
Edit the following Line:
print('Temp={0:0.1f}* Humidity={1:0.1f}%'.format(temperature, humidity))
to: print ('{0:0.1f}'.format(temperature))
so vou will get a Value only. Working great. You can get the Humidity by doing a renamed copy of AdafruitDHT.py as well with: print ('{0:0.1f}'.format(humidity))
In the Plugin you can call them with:
/home/pi/Adafruit_Python_DHT/examples/AdafruitDHT.py 22 4
eg. /home/pi/Adafruit_Python_DHT/examples/AdafruitDHT**(copy)**.py 22 4
best regards Michel

Just to include, there is a relatively* easy way using "device tree overlays" to include support for both types of sensor at the linux level, which can then be read with cat

I also ran into the Problem with old Libaries, after upgrading to octoPi RC3 and here ist, how I brought my DT22 back to life:
First, IΒ΄ve written a dht_v1.py :

# SPDX-License-Identifier:

#import time
import board
import adafruit_dht

# Initial the dht device, with data pin connected to:
dhtDevice = adafruit_dht.DHT22(board.D3, use_pulseio=False)
# you can pass DHT22 use_pulseio=False if you wouldn't like to use pulseio.
# This may be necessary on a Linux single board computer like the Raspberry Pi,
# but it will not work in CircuitPython.
# dhtDevice = adafruit_dht.DHT22(board.D18, use_pulseio=False)
temperature_c = dhtDevice.temperature
humidity = dhtDevice.humidity
            "Temp: {:.1f} *C    Humidity: {}% ".format(
                temperature_c, humidity

Now, you can call this Script in Top Temp as a customer script like this:

python3 /home/pi/dht_v1.py |cut -d ":" -f3|cut -d"%" -f1

python3 /home/pi/dht_v1.py |cut -d ":" -f2|cut -d"*" -f1

Happy printing !
