-# Project State: HA KNX Bridge
-
-## Project Description
-HA KNX Bridge is a Home Assistant custom integration that mirrors Home Assistant entities
-to KNX group addresses and accepts KNX actions to control Home Assistant entities.
-It is installed via HACS and configured through the Home Assistant UI (config flow).
-The integration should:
-- Reuse an existing Home Assistant KNX integration entry when available.
-- Allow users to add "Ports" that bind a single HA entity to KNX group addresses.
-- Auto-select appropriate KNX DPTs and request only the group addresses needed.
-- Ignore missing/empty group addresses without errors.
-
-Target compatibility: Home Assistant 2025.12 with forward compatibility to 2026.2.
-
-Project rules:
-- Keep `README.md` updated for user-relevant changes after each new version.
-- Maintain `CHANGELOG.md` with newest entries at the top.
-- Releases are created only when explicitly requested.
-- Version number must match everywhere it is referenced (manifest, changelog, README, HACS if used).
-
-## Current State (as of 2026-02-13)
-Completed:
-- Repo initialized with `main` branch and pushed to GitHub.
-- HACS metadata (`hacs.json`) and base integration scaffold created.
-- Config flow created with subentries ("Ports") for:
-  - Binary Sensor
-  - Cover
-- KNX group address validation and normalization in subentry flows.
-- Options flow skeleton added (no options yet).
-- `bcs.yaml` metadata file added for BCS store listing.
-- Bridge manager implements:
-  - Binary sensor state -> KNX send (DPT 1)
-  - Cover KNX incoming commands -> HA services
-  - Cover HA state -> KNX percent updates (DPT 5.001)
-- README includes initial DPT mapping and roadmap.
-- Project version set to 0.0.2 and `CHANGELOG.md` maintained.
-
-Files created:
-- `custom_components/ha_knx_bridge/__init__.py`
-- `custom_components/ha_knx_bridge/bridge.py`
-- `custom_components/ha_knx_bridge/config_flow.py`
-- `custom_components/ha_knx_bridge/const.py`
-- `custom_components/ha_knx_bridge/manifest.json`
-- `custom_components/ha_knx_bridge/strings.json`
-- `hacs.json`
-- `README.md`
-- `CHANGELOG.md`
-- `.gitignore`
-
-Open items / next steps:
-- Validate and format KNX group address inputs in config flow.
-- Add optional option flow for future settings.
-- Expand entity coverage (light, switch, sensor, climate).
-- Add tests (config flow, KNX mapping).
-- Improve DPT auto-selection logic per entity features.

-# Start Prompt (Use for Every New Chat)
-
-You are working on the `HA-KNX-Bridge` project.
-
-Required steps at the start of every new chat:
-1. Read `.idea/PROJECT_STATE.md` to understand the goal and current status.
-2. Scan the repository for recent code changes relevant to the request.
-3. If you make changes, update `.idea/PROJECT_STATE.md` to reflect the new state and date.
-
-Constraints:
-- Keep the project description and state accurate and concise.
-- Always write an explicit date (YYYY-MM-DD) when updating the Current State section.
-- Do not invent progress; only record what is verified in the repo.
-- After any user-relevant change and version bump, update `README.md`.
-- Maintain `CHANGELOG.md` with newest entries at the top, format:
-  - Version number
-  - Date (YYYY-MM-DD)
-  - Bullet list of changes
-- Create releases only when explicitly requested.
-- Keep the version number consistent in all files where it appears.
