Levoit Core 300s - Unable to trigger "Sleep" Mode from Automation since Update

[whistlerofficial]

Hello,

since the Update to the newest Firmware and ESPHome 2026.1.4 i am not able to trigger the "Sleep" Mode from an Automation / Developer Tools anymore.
This was possible before (Firmware from January 17 2026).

I am able to set the sleep mode manually via the HA UI.

Setting the Fan Mode via fan.set_preset_mode works for me

action: fan.set_preset_mode
metadata: {}
target:
  entity_id: fan.levoit_core300s_s3_fan
data:
  preset_mode: Sleep
