-# 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 (>=3.10), 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 (S2, S3, C3, etc.) and both IDF and Arduino frameworks.
-    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"])`, `cv.only_with_arduino`.
-    *   **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`.
-
-## 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.
-*   **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.
-
-*   **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.

+   * - Specialized handling for different field types according to protobuf spec
+   * - Templated helpers for repeated fields and messages
