ESP32 DHT11 Sensor Problem

Anas_Hmida · June 13, 2020, 1:22pm

Helllo everyone !
i have a problem that i could use some help with , i installed home assistant and using ESPHOME to control relays using my ESP32 , the relays code works very well , but then i decided to add a DHT11 sensor to my yaml and problems started showing :

INFO Uploading /data/bitanas/.pioenvs/bitanas/firmware.bin (890512 bytes)

it gets stuck there , but once i remove the sensor code , everything goes back to normal and working.
i removed my relay code and left only the sensor code , the error shows up again.

i really wish i had more knowledge in order to fix this by my self but i’m stuck can anyone help me ?

here is the code for my yaml file :

  # Enable fallback hotspot (captive portal) in case wifi connection fails

Have you tried moving your dht to a different pin? Sometimes pins have side effects. See this reference https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

Try using a different pin on the ESP.

If it’s a pin problem, you shouldn’t get the error if you disconnect the DHT and restart the board.

Hello sorry for the late reply , i have spent the last several hours trying to figure out what is wrong , until i reached the point where it uploaded the firmware but it’s stuck in a loop that i can’t get out from , here is my output :

i’m sorry if it’s too long but i couldn’t be more confused … i’m losing hope to fix this

Well from what I see it looks like it booted, did the first read of the temp and humidity from the dht which was successful, and then is trying to talk to a sensor which barfs. Guess I would need to see the sensor code.

Anas_Hmida · June 13, 2020, 10:31pm

Oh i already pasted that above !

sensor:

  - platform: dht
    pin: 14
    model: AUTO_DETECT
    temperature:
      name: "Temperature"
    humidity:
      name: "Humidity"
    update_interval: 2

Anas_Hmida · June 13, 2020, 10:34pm

Btw just a side note , the relay works WELL if i replace the sensor code with the switch code , only the DHT sensor is giving me a headache

micque · June 13, 2020, 11:55pm

I saw the dht code. What do you do with the temperature an humidity readings?

zoogara · June 14, 2020, 12:34am

@Anas_Hmida - this is a bug introduced in 1.14.4 and has been fixed in 1.15.0dev.

It affects one wire sensors including DHT11, DHT22 and Dallas.

You could either wait for the new version to come out, or install the dev version from the repository.

Note - if you install the dev version don’t forget to stop the 1.14.4 instance in HA supervisor.

Anas_Hmida · June 14, 2020, 9:19am

@zoogara THANK YOU SO MUCH , I SWITCHED TO 1.15.0DEV AND EVERYTHING WORKS

FatDash · June 15, 2020, 11:00pm

I had the exact problem with a ESP32 DEVKIT V1, DHT11, SR501. As soon as I switched to the 1.15 DEV it worked. I had been working on this for over a week. Thanks for the information.

waphass · June 16, 2020, 12:04am

Good. Can you share the procedure to switch to 1.15 DEV with us? I don’t know how to do that without breaking everything.

(a.k.a. RTFM)

zoogara · June 16, 2020, 12:44am

I use the HA Supervisor and just select the Dev version form the add-on store, so I wouldn’t have been much help for other installs - sorry.
