DHT Sensor - custom_components

Yes.
Very sad

I’m always astounded by how strictly this “open source community” project is locked down to suite the blinkered goals of a few senior developers and prevent tinkering by the people using it. The usual line being that they don’t like having to offer support for projects people are hacking together, as if all such support would be on them, which is never true in a community project.
Yes, we should absolutely be able and allowed to install our own python packages. Though I note the python and pip commands are not accessible on the terminal. The packages are surely running somewhere though so we must be able to find the pip binary and ask it to install the relevant stuff we wish to import.
If anyone knows how to access Python or Pip from the hass terminal, please say so, because the official hass administration seems to be going down the same no-right-to-repair path as apple these days of saying “sure, go ahead and make changes, but we’re going to make it as hard as possible to do.” ¬_¬

Okay, so I’ve been poking around and just taking some notes as I go.

Install the community add on “SSH & Web Terminal”
i) Ensure it is “SSH & Web Terminal” and not the more “official” one called “Terminal & SSH”. Yes they look and sound identical, but this makes a huge difference.
ii) Before starting the add on, click its “Configuration” tab and add a password (a key would be better but I’m keeping this simple for now).
iii) Back on the Info tab, where you set it to start on boot etc, turn off the stupid switch for “Protection Mode”. This causes it to hide actually useful parts of the sytem from you if it’s on, such as Python, Pip, Docker, etc.
iv) Start the addon and go to its web ui or login over an SSH terminal, however you prefer.
In the now “unprotected” terminal, run pip3 install adafruit-circuitpython-dht (oh look, it does exist after all ¬_¬)
Oh yes, the powers that be decided the primary benefit of using a Raspberry Pi over literally any other computer (it’s damned GPIO pins!) wasn’t important anymore, so we’d best install that too. pip3 install RPi.GPIO
reboot

This is where I’m a bit stumped, after rebooting, nothing has changed and in fact if I run pip3 list the installed packages have now vanished.

However, I did notice that where my manifest file listed “RPi.GPIO==0.7.1a4” and “adafruit-circuitpython-dht==3.7.0”, what I’m seeing in my pip3 freeze is showing “RPi-GPIO==0.7.1” and “adafruit-circuitpython-dht==3.7.7” so I’m going to see what happens if I update the DHT custom component to use these newer versions…

apbarratt · September 27, 2022, 12:20pm

No luck I’m afraid. I still get, like @lpt2007, the infinite spinning configuration check.
Though curiously, I cannot see where @lpt2007 found their error lines regarding the packages not installing. I’ve checked the log section but all I see there is the usual moaning warnings about custom components not being official enough for their liking.

I’m running Homeassistant Core v2022.10.3 and DHT is not working, tried to update adafruit-circuitpython-dht and rpi.gpio and changed the requirements in the dht component, but the sensor is still not working and giving ‘unknown’ instead of the temperature and humidity values.

Also tried this custom_component: GitHub - richardzone/homeassistant-dht: Support for Adafruit DHT temperature and humidity sensor and still the same errors.

megapearl · October 12, 2022, 8:35am

I got it working using a hardware ‘hack’ using the 5v instead of the 3.3v of the raspberry pi and now getting values for humidity and temperature, using above custom_component.

gaRFio01 · October 15, 2022, 3:01pm

How did you do working???
Regards

jiawku · October 17, 2022, 6:45am

Hi,
The verison of RPi.GPIO requested by dht is 0.7.1a4, while its version in rpi_GPIO is v0.7.1. The system needs gcc to compile the python wheel of RPi.GPIO v0.7.1a4. But you can simply use the same version of it in dht library. Just remove “a4” from the manifest.json of dht library.
It worked for home assistant os on raspberry pi.

tektonnic · October 18, 2022, 7:02am

Hi - can you be slightly more expansive on this please? I removed a4 but am assuming there is another library I need to add as it’s not go things working…

fer4droid · October 19, 2022, 5:35pm

Ok. It’s working now!
Simple instruction:

Remove the dht directory in \config\custom_components
(As suggest by @megapearl ) Add this repository to HACS GitHub - richardzone/homeassistant-dht: Support for Adafruit DHT temperature and humidity sensor and install the component.
(As suggest by @jiawku ) Edit the file \config\custom_components\dht\manifest.json and remove “a4” from the “0.7.1a4”.
Reboot Home Assistant.
Add the code in your .yaml file.
Check config (it should pass now) and reboot.

tektonnic · October 20, 2022, 7:13am

Thanks, I’ve followed the instruction but now my config.yaml won’t pass before restart…will have to tinker a little more

Johanf · October 24, 2022, 5:19pm

You have to restart Home Assistant before adding the configuration lines in the config.yaml. After the DHT integration is installed, then Home Assistant will pass you configuration code if it’s correctly formed. You can also restart the host, via settings, system, hardware if Home Assistant isn’t allowing to restart.

However I am personnaly struggling to get the DHT sensor on the Raspberry GPIOs working as well. Restarting and adding the code is working, but no values yet on the sensor.

Here’s my log:

gaRFio01 · November 2, 2022, 7:03am

Maybe changing the pins?

Guilherme_Gimenes · November 28, 2022, 11:40pm

perfect! working again…

after add the code, the config check wont pass… I had reboot manually… but after that it works fine.

walberjunior · December 4, 2022, 3:40am

I managed to make the sensor work with fer4droid’s tips, but my log is full of errors.

Any idea?

Guilherme_Gimenes · December 14, 2022, 3:20am

Well, I thought my DHT is working, but it isn’t. I think it is because of the library installed.
I installed a deprecated library (AdaFruit_Python_DHT) … when I check the temp and hum, it returns data correctly:

Looking at the manifest.json, its reference is “AdaFruit_CircuitPython_DHT”:

ok… I installed this one too… but I cannot see the temp and hum (maybe im using a wrong command?)
nothing happens…

Also, checking the example py… it says to check the wires… but as tested before…the wires are ok…

Whar am I doing wrong? if I cannot check the temperature and humidity using the terminal, I will never be able to check using home assistant ]

thank you!

fer4droid · January 2, 2023, 6:59pm

Yeah, 2 line of log every 30 seconds is very annoying…
I “work around” the problem by editing the file sensor.py and changing the line 183 deleting the last parameter, so the line now look like this:
@retry(reraise = True, retry = retry_if_exception_type(RuntimeError), stop = stop_after_attempt(15))

fer4droid · January 2, 2023, 7:17pm

For those of you who’s sensor doesn’t work.
Remember that non only DHT is deprecated but also the GPIO.
So try to install also the unofficial GPIO support on HACS:

walberjunior · January 2, 2023, 7:52pm

My work around was to raise the custom_components.dht.sensor log to error instead of warning

gaRFio01 · January 19, 2023, 5:55pm

So the workaround makes the custom component to work?
Thanks
