+# 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.
