Dallas temperature sensor not found after upgrade to ESPHome 2024.5.0

[mrucidlo]

The problem

Dallas temperature sensor was normally working normally with ESPHome 2024.4.x version. I have only one sensor connected. After upgrade to ESPHome 2024.5.0, sensor is not found.

Which version of ESPHome has the issue?

2024.5.0

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2024.5.3

What platform are you using?

ESP32

Board

WeMos WROOM

Component causing the issue

dallas temperature sensor

Example YAML snippet

esp32:
  board: esp32dev
  framework:
    type: arduino

dallas:
  - pin: GPIO04

sensor:
  - platform: dallas
    address: 0xbe00000f1b381628
    name: "Water Heater Temperature"

Have you tried/can you try https://github.com/persuader72/esphome-components ?

I have the same issue, annoying 🤨

I don’t think this is related. I have a Dallas soldered to a gpio on esp32.

Not solved with ESPHome 2024.5.1 nor with ESPHome 2024.5.2

I had this issue and I switched the GPIO pin I was using and that seemed to fix the issue.

I’m using GPIO pin 21.
It worked for years but after the upgrade it no longer does. I don't see a hardware cause.
What pin are you using?

I’m using GPIO23 now.

After some playing around, nothing with the board I have and ESPHome version 2024.5.3 worked.
So I replaced Dallas ESPHome component (sorry ESPHome) with https://github.com/nrandell/dallasng. Temperature sensor is back, same pin as before.

My code now looks like:

external_components:

• source: github://nrandell/dallasng

dallasng:

• pin: GPIO4
  update_interval: 30s

sensor:

• platform: dallasng
  index: 0
  name: "Water Heater Temperature"
  resolution: 12
  filters:
  • filter_out: NAN

Thanks for sharing, this works for me as well

I updated to 2024.5.3 and now my temperature sensors also stopped working.
Guess I'll give dallasng a try for the time being.

Thanks, this worked for me too!

thank you - thank you. crazy that i had to dig so far to find the answer and that esphome has not been able to address for this ESP board?

Maybe you can test the new one_wire component that will replace the original dallas component esphome/esphome#6860

wow that is a fresh PR - thanks for letting me know - it works here!
