An Anova Precision Cooker connected through ESPHome can revert from Fahrenheit to Celsius without being asked, leaving its display and converted readings out of step. ESPHome reapplies the configured temperature scale before each status check instead of setting it only when Bluetooth first connects.
Contributor raykholo tested the correction on a Bluetooth-only Precision Cooker 1.0: the display returned to Fahrenheit without restarting the ESP32, and temperatures tracked correctly while heating from Home Assistant. This is raykholo's first contribution to ESPHome, with review and approval from jesserockz.
