v0.4.0

[lnagel]

New Features

• Zone counting sensors and controller-level heat request (Refactor heat request to controller-level, add zone counting sensors, rename entities #90) — Three new controller-level sensors (zones_flowing, zones_heating, zones_window) provide granular visibility into zone states. The heat request signal has been moved from a per-zone dictionary to a single controller-level binary sensor.
• Zone heat state (Refactor heat request to controller-level, add zone counting sensors, rename entities #90) — New ZoneState.heat boolean derived from flow AND supply coefficient > 10%, with a corresponding remaining_duration property for tracking remaining zone run time.
• Deferred controller initialization (Defer controller initialization until watched entities report valid state #91) — The controller now stays in INITIALIZING until all watched entities (valves, DHW, heat request, supply/outdoor temp sensors) report valid state, preventing commands from being issued to entities that haven't reported in yet. After a 120-second timeout, it logs a warning and proceeds regardless.
• Zone remaining duration sensor (Add remaining duration sensor for UFH zones #96) — New per-zone sensor displaying the remaining time (in seconds) for the current zone operation. Uses Home Assistant's duration device class for proper formatting.

Bug Fixes

• Preserve supply target temp during initialization (Preserve supply_target_temp when outdoor sensor unavailable during init #97) — When the outdoor sensor hasn't reported yet during INITIALIZING, the controller no longer overwrites the supply target temperature restored from saved state with the static config default. The outdoor temp update is now skipped when the value is None during initialization.

Breaking Changes

Entity IDs change for existing installations (#90):

• binary_sensor.*_blocked → binary_sensor.*_window
• binary_sensor.*_heat_request (zone-level) → binary_sensor.*_heat
• sensor.*_requesting_zones → sensor.*_zones_flowing (+ new zones_heating, zones_window)
• New: binary_sensor.*_heat_request (now at controller level)

Automations or dashboards referencing old entity IDs will need updating.

Refactoring / Internal

• Weather compensation documented in README (Document weather compensation feature in README #89) — Added heating curve / outdoor temperature compensation to the comparison table, key differentiators, and requirements sections.
• Controller status and init tracking moved to controller (Move controller status and init tracking from coordinator to controller #92) — ControllerStatus and init_started_at moved from coordinator to ControllerState. New update_status() method on HeatingController handles zone status aggregation and init timeout. Coordinator reduced to a thin delegation layer.
• Remaining coordinator business logic moved to controller (Move remaining coordinator business logic to controller #94) — Fail-safe zone detection, DHW transition handling, and observation period transitions all moved from coordinator to HeatingController. Includes storage migration V2 → V3 for last_force_update tracking.
• Remove unused valve_on_since field — Cleaned up unused valve_on_since field from ZoneState.
