Walkthrough

ESPHome version bumped from 25.7.18.1 to 26.3.2.1 in the Core configuration. A character encoding change detected in the BME280 Temperature Offset unit_of_measurement field requires verification.

Poem

🐰 A version bump hops into place,
From 25 to 26, picking up pace!
But oh, a strange glyph in the temperature field—
Did encoding mischief get revealed?
Let's verify this character's true name! 🌡️

In `@Integrations/ESPHome/Core.yaml`:
- Line 145: The unit_of_measurement value contains a garbled character ("�C");
update the YAML key unit_of_measurement to use the correct degree Celsius symbol
(°C) instead of the replacement character so the UI displays temperatures
properly—locate the unit_of_measurement entry in the
Integrations/ESPHome/Core.yaml and replace the corrupted character with the
proper ° character.
