Congrats to the esp home team.

Yeah the wifi on mesh network changes look good - I guess I will have to see what breaks for the other changes :slight_smile:

I’ve already updated a lot of ESP’s and haven’t had any issues.

I’m only worried about the Select changes - and they’ll be good until May next year by which I’ll have forgotten completely about them… :joy:

Kudos to the ESPHome team for making efficiency improvements a priority!

Too often these days we see developers sitting at their bleeding-edge, high-end machines designing things which can only run on equally beefy hardware. Efficiency is often ignored when using high-level languages where all the real work is done by a “black box” module the developer just includes.

It’s great to see a project where bytes of data and CPU cycles matter.

I have some old ESP8266’s still happily running some fairly complex tasks. The last two updates saw small but noticeable improvements in the memory footprint of ESPHome on these devices. I can’t wait to see what this one brings.

Thanks Devs!!!

Yeah, there has been a remarkable and genuinely positive development across the entire ESPHome ecosystem lately. Besides what @CaptTom said, both the ESPHome integration and the in-code documentation have improved noticeably, and the user guides are clearer and more helpful than before.

It really shows how much care and effort the team is putting into the project!

Thank you all for your amazing work!

Was that after updating esphome to 2025.11.0 or after updating a device?

I want to upgrade esphome to that version, but i dont know if wait until .1 just in case.

11

after updating to 2025.11.0 . both update and a new device does not compile now. some devices work and can update. i have 6 that is not updatable

12

Are you using the ESPhome Builder integration in Home Assistant OS (HAOS) ?

13

yes and i have 25 devices in it

i restarted the system to make sure all was restarted but still errors.

14

Did you try a clean build ie ESPHome Builder → “Tree dots” → “Clean Build Files” ?

15

i did. tried on multible devices. and no cigar

16

Hmm, I’m running out of ideas. I’m assuming you’ve already updated ESPHome Builder to 2025.11?

17

yep the error came after the update. it seems that there is a missing a file or folder. can i uninstall esphome builder and reinstall without loosing my yaml files?

18

It seems there are some CMake references not working (don’t ask me why), but could you try adding this to “esphome:” as a temporary workaround:

esphome:
  . . .
  . . .
  platformio_options:
    # Force platform to re-download all tools
    platform: https://github.com/pioarduino/platform-espressif32/releases/download/55.03.31-2/platform-espressif32.zip
    platform_packages:
      - "framework-espidf @ ~3.50501.0"

Then Save → Install → Manual Download, just to see if it compiles…

EDIT:
I recommend opening an issue on the ESPHome GitHub so the developers can discuss and follow up on it with you: https://github.com/esphome/esphome/issues

19

workaround did not work. but many thanks. i will try github

Hi,

Just adding a ‘me too’:

Together with the ESP32 problem three other services failed as well (Although I don’t see what they have to do with the ESPHome upgrade):

Miele
Overkiz
Audi

Rolled back to the previous ESP Home to 2025.10.5 and a boot of HomeAssistant got evrything working again for me…
