Bedtime "Only today" override now syncs reliably (#113)
The Bedtime switch could previously show an incorrect state when using the "Only today" option in the Family Link app. In some cases, enabling or disabling Bedtime for the current evening was not properly reflected in Home Assistant, causing the switch.*_bedtime entity to appear active when it had been turned off (or the opposite).
What changed
- The Bedtime switch now reads its current state from the authoritative per-day override applied by Google, instead of relying on an indirect heuristic that could miss cases where an "Only today" OFF leaves no active window to detect.
- Google accumulates daily overrides instead of replacing them, meaning a given day can contain multiple entries. The integration now always uses the most recent override, preventing stale values from taking precedence over a newer toggle.
Result
Toggling Bedtime with the "Only today" option in the Family Link app is now correctly reflected in Home Assistant within a single refresh cycle, in both enable and disable directions. This has been verified on a real supervised device.
No configuration changes are required - just update and restart Home Assistant.
