# Package: BYD Charging Schedule At Home
# File:    byd_charging_schedule_athome.yaml
# Version: v1.0.1
# Date:    2026-06-19
#
# Purpose:
#   Enables the BYD Atto 3 charging schedule when the car arrives home.
#   Disables the schedule only after the car has been confirmed away for a
#   configurable delay, to avoid rapid toggling from uncertain presence detection.
#
# Behaviour:
#   - Confirmed arrival home:
#       Turns ON switch.atto_3_schedule_enabled,
#       but only if the car had previously been confirmed away.
#
#   - Confirmed away:
#       After away_confirm_minutes, turns OFF switch.atto_3_schedule_enabled.
#
#   - Manual control:
#       If the car is already home and the user or another HA automation turns
#       the schedule OFF manually, this package will not turn it back ON unless
#       the car is later confirmed away and then arrives home again.
#
# Notes:
#   - Home Assistant usually stores the device_tracker home state as "home",
#     even if the UI displays "At Home".
#   - Change away_confirm_minutes below if you want a longer/shorter debounce.
