+# ESPHome AI Collaboration Guide
+
+This document provides essential context for AI models interacting with this project. Adhering to these guidelines will ensure consistency and maintain code quality.
+
+## 1. Project Overview & Purpose
+
+*   **Primary Goal:** ESPHome is a system to configure microcontrollers (like ESP32, ESP8266, RP2040, and LibreTiny-based chips) using simple yet powerful YAML configuration files. It generates C++ firmware that can be compiled and flashed to these devices, allowing users to control them remotely through home automation systems.
+*   **Business Domain:** Internet of Things (IoT), Home Automation.
+
+## 2. Core Technologies & Stack
+
+*   **Languages:** Python (>=3.11), C++ (gnu++20)
+*   **Frameworks & Runtimes:** PlatformIO, Arduino, ESP-IDF.
+*   **Build Systems:** PlatformIO is the primary build system. CMake is used as an alternative.
+*   **Configuration:** YAML.
+*   **Key Libraries/Dependencies:**
+    *   **Python:** `voluptuous` (for configuration validation), `PyYAML` (for parsing configuration files), `paho-mqtt` (for MQTT communication), `tornado` (for the web server), `aioesphomeapi` (for the native API).
+    *   **C++:** `ArduinoJson` (for JSON serialization/deserialization), `AsyncMqttClient-esphome` (for MQTT), `ESPAsyncWebServer` (for the web server).
+*   **Package Manager(s):** `pip` (for Python dependencies), `platformio` (for C++/PlatformIO dependencies).
+*   **Communication Protocols:** Protobuf (for native API), MQTT, HTTP.
+
+## 3. Architectural Patterns
+
+*   **Overall Architecture:** The project follows a code-generation architecture. The Python code parses user-defined YAML configuration files and generates C++ source code. This C++ code is then compiled and flashed to the target microcontroller using PlatformIO.
+
+*   **Directory Structure Philosophy:**
+    *   `/esphome`: Contains the core Python source code for the ESPHome application.
+    *   `/esphome/components`: Contains the individual components that can be used in ESPHome configurations. Each component is a self-contained unit with its own C++ and Python code.
+    *   `/tests`: Contains all unit and integration tests for the Python code.
+    *   `/docker`: Contains Docker-related files for building and running ESPHome in a container.
+    *   `/script`: Contains helper scripts for development and maintenance.
+
+*   **Core Architectural Components:**
+    1.  **Configuration System** (`esphome/config*.py`): Handles YAML parsing and validation using Voluptuous, schema definitions, and multi-platform configurations.
+    2.  **Code Generation** (`esphome/codegen.py`, `esphome/cpp_generator.py`): Manages Python to C++ code generation, template processing, and build flag management.
+    3.  **Component System** (`esphome/components/`): Contains modular hardware and software components with platform-specific implementations and dependency management.
+    4.  **Core Framework** (`esphome/core/`): Manages the application lifecycle, hardware abstraction, and component registration.
+    5.  **Dashboard** (`esphome/dashboard/`): A web-based interface for device configuration, management, and OTA updates.
+
+*   **Platform Support:**
+    1.  **ESP32** (`components/esp32/`): Espressif ESP32 family. Supports multiple variants (Original, C2, C3, C5, C6, H2, P4, S2, S3) with ESP-IDF framework. Arduino framework supports only a subset of the variants (Original, C3, S2, S3).
+    2.  **ESP8266** (`components/esp8266/`): Espressif ESP8266. Arduino framework only, with memory constraints.
+    3.  **RP2040** (`components/rp2040/`): Raspberry Pi Pico/RP2040. Arduino framework with PIO (Programmable I/O) support.
+    4.  **LibreTiny** (`components/libretiny/`): Realtek and Beken chips. Supports multiple chip families and auto-generated components.
+
+## 4. Coding Conventions & Style Guide
+
+*   **Formatting:**
+    *   **Python:** Uses `ruff` and `flake8` for linting and formatting. Configuration is in `pyproject.toml`.
+    *   **C++:** Uses `clang-format` for formatting. Configuration is in `.clang-format`.
+
+*   **Naming Conventions:**
+    *   **Python:** Follows PEP 8. Use clear, descriptive names following snake_case.
+    *   **C++:** Follows the Google C++ Style Guide.
+
+*   **Component Structure:**
+    *   **Standard Files:**
+        ```
+        components/[component_name]/
+        ├── __init__.py          # Component configuration schema and code generation
+        ├── [component].h        # C++ header file (if needed)
+        ├── [component].cpp      # C++ implementation (if needed)
+        └── [platform]/          # Platform-specific implementations
+            ├── __init__.py      # Platform-specific configuration
+            ├── [platform].h     # Platform C++ header
+            └── [platform].cpp   # Platform C++ implementation
+        ```
+
+    *   **Component Metadata:**
+        - `DEPENDENCIES`: List of required components
+        - `AUTO_LOAD`: Components to automatically load
+        - `CONFLICTS_WITH`: Incompatible components
+        - `CODEOWNERS`: GitHub usernames responsible for maintenance
+        - `MULTI_CONF`: Whether multiple instances are allowed
+
+*   **Code Generation & Common Patterns:**
+    *   **Configuration Schema Pattern:**
+        ```python
+        import esphome.codegen as cg
+        import esphome.config_validation as cv
+        from esphome.const import CONF_KEY, CONF_ID
+
+        CONF_PARAM = "param"  # A constant that does not yet exist in esphome/const.py
+
+        my_component_ns = cg.esphome_ns.namespace("my_component")
+        MyComponent = my_component_ns.class_("MyComponent", cg.Component)
+
+        CONFIG_SCHEMA = cv.Schema({
+            cv.GenerateID(): cv.declare_id(MyComponent),
+            cv.Required(CONF_KEY): cv.string,
+            cv.Optional(CONF_PARAM, default=42): cv.int_,
+        }).extend(cv.COMPONENT_SCHEMA)
+
+        async def to_code(config):
+            var = cg.new_Pvariable(config[CONF_ID])
+            await cg.register_component(var, config)
+            cg.add(var.set_key(config[CONF_KEY]))
+            cg.add(var.set_param(config[CONF_PARAM]))
+        ```
+
+    *   **C++ Class Pattern:**
+        ```cpp
+        namespace esphome {
+        namespace my_component {
+
+        class MyComponent : public Component {
+         public:
+          void setup() override;
+          void loop() override;
+          void dump_config() override;
+
+          void set_key(const std::string &key) { this->key_ = key; }
+          void set_param(int param) { this->param_ = param; }
+
+         protected:
+          std::string key_;
+          int param_{0};
+        };
+
+        }  // namespace my_component
+        }  // namespace esphome
+        ```
+
+    *   **Common Component Examples:**
+        - **Sensor:**
+          ```python
+          from esphome.components import sensor
+          CONFIG_SCHEMA = sensor.sensor_schema(MySensor).extend(cv.polling_component_schema("60s"))
+          async def to_code(config):
+              var = await sensor.new_sensor(config)
+              await cg.register_component(var, config)
+          ```
+
+        - **Binary Sensor:**
+          ```python
+          from esphome.components import binary_sensor
+          CONFIG_SCHEMA = binary_sensor.binary_sensor_schema().extend({ ... })
+          async def to_code(config):
+              var = await binary_sensor.new_binary_sensor(config)
+          ```
+
+        - **Switch:**
+          ```python
+          from esphome.components import switch
+          CONFIG_SCHEMA = switch.switch_schema().extend({ ... })
+          async def to_code(config):
+              var = await switch.new_switch(config)
+          ```
+
+*   **Configuration Validation:**
+    *   **Common Validators:** `cv.int_`, `cv.float_`, `cv.string`, `cv.boolean`, `cv.int_range(min=0, max=100)`, `cv.positive_int`, `cv.percentage`.
+    *   **Complex Validation:** `cv.All(cv.string, cv.Length(min=1, max=50))`, `cv.Any(cv.int_, cv.string)`.
+    *   **Platform-Specific:** `cv.only_on(["esp32", "esp8266"])`, `esp32.only_on_variant(...)`, `cv.only_on_esp32`, `cv.only_on_esp8266`, `cv.only_on_rp2040`.
+    *   **Framework-Specific:** `cv.only_with_framework(...)`, `cv.only_with_arduino`, `cv.only_with_esp_idf`.
+    *   **Schema Extensions:**
+        ```python
+        CONFIG_SCHEMA = cv.Schema({ ... })
+         .extend(cv.COMPONENT_SCHEMA)
+         .extend(uart.UART_DEVICE_SCHEMA)
+         .extend(i2c.i2c_device_schema(0x48))
+         .extend(spi.spi_device_schema(cs_pin_required=True))
+        ```
+
+## 5. Key Files & Entrypoints
+
+*   **Main Entrypoint(s):** `esphome/__main__.py` is the main entrypoint for the ESPHome command-line interface.
+*   **Configuration:**
+    *   `pyproject.toml`: Defines the Python project metadata and dependencies.
+    *   `platformio.ini`: Configures the PlatformIO build environments for different microcontrollers.
+    *   `.pre-commit-config.yaml`: Configures the pre-commit hooks for linting and formatting.
+*   **CI/CD Pipeline:** Defined in `.github/workflows`.
+*   **Static Analysis & Development:**
+    *   `esphome/core/defines.h`: A comprehensive header file containing all `#define` directives that can be added by components using `cg.add_define()` in Python. This file is used exclusively for development, static analysis tools, and CI testing - it is not used during runtime compilation. When developing components that add new defines, they must be added to this file to ensure proper IDE support and static analysis coverage. The file includes feature flags, build configurations, and platform-specific defines that help static analyzers understand the complete codebase without needing to compile for specific platforms.
+
+## 6. Development & Testing Workflow
+
+*   **Local Development Environment:** Use the provided Docker container or create a Python virtual environment and install dependencies from `requirements_dev.txt`.
+*   **Running Commands:** Use the `script/run-in-env.py` script to execute commands within the project's virtual environment. For example, to run the linter: `python3 script/run-in-env.py pre-commit run`.
+*   **Testing:**
+    *   **Python:** Run unit tests with `pytest`.
+    *   **C++:** Use `clang-tidy` for static analysis.
+    *   **Component Tests:** YAML-based compilation tests are located in `tests/`. The structure is as follows:
+        ```
+        tests/
+        ├── test_build_components/ # Base test configurations
+        └── components/[component]/ # Component-specific tests
+        ```
+        Run them using `script/test_build_components`. Use `-c <component>` to test specific components and `-t <target>` for specific platforms.
+    *   **Testing All Components Together:** To verify that all components can be tested together without ID conflicts or configuration issues, use:
+        ```bash
+        ./script/test_component_grouping.py -e config --all
+        ```
+        This tests all components in a single build to catch conflicts that might not appear when testing components individually. Use `-e config` for fast configuration validation, or `-e compile` for full compilation testing.
+*   **Debugging and Troubleshooting:**
+    *   **Debug Tools:**
+        - `esphome config <file>.yaml` to validate configuration.
+        - `esphome compile <file>.yaml` to compile without uploading.
+        - Check the Dashboard for real-time logs.
+        - Use component-specific debug logging.
+    *   **Common Issues:**
+        - **Import Errors**: Check component dependencies and `PYTHONPATH`.
+        - **Validation Errors**: Review configuration schema definitions.
+        - **Build Errors**: Check platform compatibility and library versions.
+        - **Runtime Errors**: Review generated C++ code and component logic.
+
+## 7. Specific Instructions for AI Collaboration
+
+*   **Contribution Workflow (Pull Request Process):**
+    1.  **Fork & Branch:** Create a new branch in your fork.
+    2.  **Make Changes:** Adhere to all coding conventions and patterns.
+    3.  **Test:** Create component tests for all supported platforms and run the full test suite locally.
+    4.  **Lint:** Run `pre-commit` to ensure code is compliant.
+    5.  **Commit:** Commit your changes. There is no strict format for commit messages.
+    6.  **Pull Request:** Submit a PR against the `dev` branch. The Pull Request title should have a prefix of the component being worked on (e.g., `[display] Fix bug`, `[abc123] Add new component`). Update documentation, examples, and add `CODEOWNERS` entries as needed. Pull requests should always be made with the PULL_REQUEST_TEMPLATE.md template filled out correctly.
+
+*   **Documentation Contributions:**
+    *   Documentation is hosted in the separate `esphome/esphome-docs` repository.
+    *   The contribution workflow is the same as for the codebase.
+
+*   **Best Practices:**
+    *   **Component Development:** Keep dependencies minimal, provide clear error messages, and write comprehensive docstrings and tests.
+    *   **Code Generation:** Generate minimal and efficient C++ code. Validate all user inputs thoroughly. Support multiple platform variations.
+    *   **Configuration Design:** Aim for simplicity with sensible defaults, while allowing for advanced customization.
+    *   **Embedded Systems Optimization:** ESPHome targets resource-constrained microcontrollers. Be mindful of flash size and RAM usage.
+
+        **STL Container Guidelines:**
+
+        ESPHome runs on embedded systems with limited resources. Choose containers carefully:
+
+        1. **Compile-time-known sizes:** Use `std::array` instead of `std::vector` when size is known at compile time.
+           ```cpp
+           // Bad - generates STL realloc code
+           std::vector<int> values;
+
+           // Good - no dynamic allocation
+           std::array<int, MAX_VALUES> values;
+           ```
+           Use `cg.add_define("MAX_VALUES", count)` to set the size from Python configuration.
+
+           **For byte buffers:** Avoid `std::vector<uint8_t>` unless the buffer needs to grow. Use `std::unique_ptr<uint8_t[]>` instead.
+
+           > **Note:** `std::unique_ptr<uint8_t[]>` does **not** provide bounds checking or iterator support like `std::vector<uint8_t>`. Use it only when you do not need these features and want minimal overhead.
+
+           ```cpp
+           // Bad - STL overhead for simple byte buffer
+           std::vector<uint8_t> buffer;
+           buffer.resize(256);
+
+           // Good - minimal overhead, single allocation
+           std::unique_ptr<uint8_t[]> buffer = std::make_unique<uint8_t[]>(256);
+           // Or if size is constant:
+           std::array<uint8_t, 256> buffer;
+           ```
+
+        2. **Compile-time-known fixed sizes with vector-like API:** Use `StaticVector` from `esphome/core/helpers.h` for fixed-size stack allocation with `push_back()` interface.
+           ```cpp
+           // Bad - generates STL realloc code (_M_realloc_insert)
+           std::vector<ServiceRecord> services;
+           services.reserve(5);  // Still includes reallocation machinery
+
+           // Good - compile-time fixed size, stack allocated, no reallocation machinery
+           StaticVector<ServiceRecord, MAX_SERVICES> services;  // Allocates all MAX_SERVICES on stack
+           services.push_back(record1);  // Tracks count but all slots allocated
+           ```
+           Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.
+           Like `std::array` but with vector-like API (`push_back()`, `size()`) and no STL reallocation code.
+
+        3. **Runtime-known sizes:** Use `FixedVector` from `esphome/core/helpers.h` when the size is only known at runtime initialization.
+           ```cpp
+           // Bad - generates STL realloc code (_M_realloc_insert)
+           std::vector<TxtRecord> txt_records;
+           txt_records.reserve(5);  // Still includes reallocation machinery
+
+           // Good - runtime size, single allocation, no reallocation machinery
+           FixedVector<TxtRecord> txt_records;
+           txt_records.init(record_count);  // Initialize with exact size at runtime
+           ```
+           **Benefits:**
+           - Eliminates `_M_realloc_insert`, `_M_default_append` template instantiations (saves 200-500 bytes per instance)
+           - Single allocation, no upper bound needed
+           - No reallocation overhead
+           - Compatible with protobuf code generation when using `[(fixed_vector) = true]` option
+
+        4. **Small datasets (1-16 elements):** Use `std::vector` or `std::array` with simple structs instead of `std::map`/`std::set`/`std::unordered_map`.
+           ```cpp
+           // Bad - 2KB+ overhead for red-black tree/hash table
+           std::map<std::string, int> small_lookup;
+           std::unordered_map<int, std::string> tiny_map;
+
+           // Good - simple struct with linear search (std::vector is fine)
+           struct LookupEntry {
+             const char *key;
+             int value;
+           };
+           std::vector<LookupEntry> small_lookup = {
+             {"key1", 10},
+             {"key2", 20},
+             {"key3", 30},
+           };
+           // Or std::array if size is compile-time constant:
+           // std::array<LookupEntry, 3> small_lookup = {{ ... }};
+           ```
+           Linear search on small datasets (1-16 elements) is often faster than hashing/tree overhead, but this depends on lookup frequency and access patterns. For frequent lookups in hot code paths, the O(1) vs O(n) complexity difference may still matter even for small datasets. `std::vector` with simple structs is usually fine—it's the heavy containers (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows otherwise.
+
+        5. **Detection:** Look for these patterns in compiler output:
+           - Large code sections with STL symbols (vector, map, set)
+           - `alloc`, `realloc`, `dealloc` in symbol names
+           - `_M_realloc_insert`, `_M_default_append` (vector reallocation)
+           - Red-black tree code (`rb_tree`, `_Rb_tree`)
+           - Hash table infrastructure (`unordered_map`, `hash`)
+
+        **When to optimize:**
+        - Core components (API, network, logger)
+        - Widely-used components (mdns, wifi, ble)
+        - Components causing flash size complaints
+
+        **When not to optimize:**
+        - Single-use niche components
+        - Code where readability matters more than bytes
+        - Already using appropriate containers
+
+    *   **State Management:** Use `CORE.data` for component state that needs to persist during configuration generation. Avoid module-level mutable globals.
+
+        **Bad Pattern (Module-Level Globals):**
+        ```python
+        # Don't do this - state persists between compilation runs
+        _component_state = []
+        _use_feature = None
+
+        def enable_feature():
+            global _use_feature
+            _use_feature = True
+        ```
+
+        **Good Pattern (CORE.data with Helpers):**
+        ```python
+        from esphome.core import CORE
+
+        # Keys for CORE.data storage
+        COMPONENT_STATE_KEY = "my_component_state"
+        USE_FEATURE_KEY = "my_component_use_feature"
+
+        def _get_component_state() -> list:
+            """Get component state from CORE.data."""
+            return CORE.data.setdefault(COMPONENT_STATE_KEY, [])
+
+        def _get_use_feature() -> bool | None:
+            """Get feature flag from CORE.data."""
+            return CORE.data.get(USE_FEATURE_KEY)
+
+        def _set_use_feature(value: bool) -> None:
+            """Set feature flag in CORE.data."""
+            CORE.data[USE_FEATURE_KEY] = value
+
+        def enable_feature():
+            _set_use_feature(True)
+        ```
+
+        **Why this matters:**
+        - Module-level globals persist between compilation runs if the dashboard doesn't fork/exec
+        - `CORE.data` automatically clears between runs
+        - Typed helper functions provide better IDE support and maintainability
+        - Encapsulation makes state management explicit and testable
+
+*   **Security:** Be mindful of security when making changes to the API, web server, or any other network-related code. Do not hardcode secrets or keys.
+
+*   **Dependencies & Build System Integration:**
+    *   **Python:** When adding a new Python dependency, add it to the appropriate `requirements*.txt` file and `pyproject.toml`.
+    *   **C++ / PlatformIO:** When adding a new C++ dependency, add it to `platformio.ini` and use `cg.add_library`.
+    *   **Build Flags:** Use `cg.add_build_flag(...)` to add compiler flags.

+            of the old issues, as many of them have already been resolved with
+            the latest updates.
+
+            Please make sure to update to the latest ESPHome version and
