ERROR Unable to load component dht.sensor: #1

Closed aheath70 closed 1 year ago

aheath70 commented 1 year ago

Found your custom DHT component whilst struggling with intermittent NAN results from a DHT22. Hoping that it might solve the issue.

I am getting the following error when trying to install to my ESP8266:

ERROR Unable to load component dht.sensor:

sensor.dht: [source /config/esphome/esp1.yaml:89]

  Platform not found: 'sensor.dht'.

I added the following to my YAML file as described in your Home Assistant post.

esphome:
  ...
  platformio_options:
    lib_deps: diaoul/DHTNew@1.0.0

...

external_components:
  - source: github://gb53smith/esphome@dev1
    components: [dht]

The esphome syntax has changed since I first experimented with external components. I have updated sensors.py and dht.h to get it working again for you. See yaml/plants.yaml for use example. Reference the external component using this method:

external_components:
### This long form works. refresh option is only needed for changes less than 24 hours old
  - source:
      type: git
      url: https://github.com:/gb53smith/esphome
      ref: main
    components: [dht]
    refresh: 0s

My issue with the older esphome version was unexpected temperature values and not NaN values. My DHT22 device is powered by 3.3V, has a 4K7 ohm pullup resistor on the data signal and a 100 nF capacitor across the power supply.

A esphome developer changed their code to fix my issue so I don't use the external component now. This was an experiment to just plug-in a known good component library from the PlatformIO repository. Esphome developers prefer to copy and modify source code from other sources for better control, I guess.

Thanks for the background. I am just trying to confirm if the problems I am having are related the default DHT library being used by ESPHOME or whether it is the cheap DHT sensors I have bought.

When I first built these sensors, I used Arduino and had the same NAN issues that I am having now with ESPHOME. I found an alternate library which resolved the issue on Arduino. I had hope that the DHTNew library might assist with ESPHOME, as one of the notes says "No more NANs".

Anyway, thanks for updating the component. I have updated my YAML as per your instructions. I am now getting the folllowing:-

Try cleaning build files and run again. Also, use the latest esphome 2022.10.2 Here is my log file. I don't get a warning about "Please upgrade to the PlatformIO Core 6" I also don't see "Updating https://github.com:/gb53smith/esphome@main" ?

Cleaned build files and tried again, and it failed with the same result. The I realised, I was running an old version of the Home Assistant ESPHOME add-on. Not sure what went wrong there as there were no updates pending, but it was dated March of 2022. I went into the HA add-on store, and there was a new version of ESPHOME, so I installed it, and low and behold I had two version of the ESPHOME addon. Anyway, I deleted the old and updated all my devices.

I was able to then flash my ESP with your code. That is the good news. The bad news is that it made no difference to my NAN issue with the DHT. In fact, the upgrade to the latest ESPHOME has made it worse. Previously, I was getting NAN's intermittently. Since the upgrade, I have failed to get a reading.

Time to purchase another brand of DHT22. Mine is an AOSONG AM2302 on a PCB with a 4K7 Pullup resistor and a 100 nF power supply bypass capacitor. Works from a 3.3V power supply.

Interesting ... mine is the same. At least if the markings on the sensor are to be believed. DHT22 on a PCB. Just not sure it is what it says it is ...

Is your PCB red or blue? Not sure if it makes any material difference, but mine is blue. It looks like it has a pullup resistor and a capacitor on it, but stuffed if I can identify specifics of what they are.

Back to the drawing board me thinks. Thanks for your help. I am feeling deflated now. Wondering whether I might better off throwing out the old ESP8266's and replacing with ESP32's. I have 6 of these sensors around the house and they are all giving a little bit of grief. I don't have spare ESP32's to test on though.

My DHT22 is on a RED PCB. It was made by Keyes with part number 140C80. The Keyes part seems to be unavailable now but I saw other products with the same part number. To verify the pullup, connect a 10K ohm resistor to ground on the data line. The voltage should drop from 3.3V to 2.24 V. Check that you can read the ESP8266 pin you are using. Remove the DHT22 and connect a toggle switch with pullup to the same pin. I used GPIO pin 2 which is labeled as D4 on my ESP8266. If you are just reading the DHT22 the ESP8266 should be adequate and the ESP32 overkill. My last ESP8266 purchase was IZOKEE D1 Mini. It is smaller than the older NodeMCU LUA. You cannot supply much current from the 3.3V regulator on the D1 Mini. Mine has a DE=A1D voltage regulator which is good for an extra 50 mA for 3.3V external components.

Not sure it is worth the time to get a non-standard DHT22 working.
If you have an Arduino library that works, it is probably available in PlatformIO. EspHome is built on top of PlatformIO so it is possible to build a wrapper around the PlatformIO library to get it working in EspHome. This repository shows an example of the wrapper technique. Over the years I have used Arduino, PlatformIO and EspHome for my IOT devices that connect to Home Assistant. EspHome is by far the easiest to use and now supports most devices.

... it is definitely something with ESPHOME. I decided to try Tasmota on the ESP8266 with the DHT in there - the same one that has been giving me NAN errors, and it has been running all day without a singe issue, happily reporting temperature and humidity. Maybe I will just stick with Tasmota I think. It has survived numerous restarts, reflashing the image multiple times, and it hasn't missed a beat.

I don't expect you to anything about this. You strike me as the kind of person who might like to know.
