The latest update to esphome 2024.10.0 causes the following issue with my emporia vue 2.
‘failed to read from sensor due to i2c error’
I rolled back to my previous esphome version 2024.9.2 and the problem disappears.
I experienced the same thing and also rolled back to fix this on my Vue2. Side but related question, I have about 15 ESPHome devices and they all seemed to upgrade to 2024.10.0 fine except the first of my 3 Emporia Vue devices. After the first one presented the error I did not do the others 2 vue devices and decided to roll back. I rolled back the integration then reinstalled the Vue config so it would roll back. It now functions as it did before. However the other 12 devices I upgraded before the vue are still on 2024.10.0 and seem to be functioning. Is there a need for me to roll all of these back as well?

I had some issues with a display not showing any values today after updating to ESPhome 2024.10.0. Solved by changing I2C frequency:
Found the culprit: frequency of I2C bus A (to which the display is connected) was set to 400kHz → display not working
After setting it to 100kHz → display working again, also with 200kHz.
Just curious why it has been working before with 2024.09.2 with 400kHz…
Anyways, case closed.
Maybe this could help in your case too?
I have the same issue with 2024.10.0. Rolling back to 2024.9.2 resolved the issue for me as well. Following this thread.

I had the same issue with my Emporia Vue 3 i2c communication after the 2024.10 upgrade. I was using 150kHz frequency. Changing that frequency to 200kHz resolves the issue (though I do have random read errors again that were resolved by using 150 kHz).
Same here, emporia vue 2 breaks with the I2C read error after 2024.10.0, had to rollback and it started working again

I had to roll back too. Can we file a bug report?

I have the same problem. Lowering the i2c frequency did not fix the problem.

On a Vue2, I had to change the frequency to 400khz and add a timeout.
frequency: 400kHz # recommended range is 50-200kHz
timeout: 1ms

### The problem
Upgrading my Emporia Vue2 to 2024.10.0 broke my device; it wo… uld constantly throw i2c timeouts:

**I've tried flashing via home assistant integration as well as manually uploading via docker image** remote OTA, and 2024.10.0 has consistent results; Downgrading back to 2024.9.2 resolved the i2C issues.
