+    *   **C++:** Follows the Google C++ Style Guide with these specifics (following clang-tidy conventions):
+        - Function, method, and variable names: `lower_snake_case`
+        - Class/struct/enum names: `UpperCamelCase`
+        - Top-level constants (global/namespace scope): `UPPER_SNAKE_CASE`
+        - Function-local constants: `lower_snake_case`
+        - Protected/private fields: `lower_snake_case_with_trailing_underscore_`
+        - Favor descriptive names over abbreviations
+
+*   **C++ Field Visibility:**
+    *   **Prefer `protected`:** Use `protected` for most class fields to enable extensibility and testing. Fields should be `lower_snake_case_with_trailing_underscore_`.
+    *   **Use `private` for safety-critical cases:** Use `private` visibility when direct field access could introduce bugs or violate invariants:
+        1. **Pointer lifetime issues:** When setters validate and store pointers from known lists to prevent dangling references.
+           ```cpp
+           // Helper to find matching string in vector and return its pointer
+           inline const char *vector_find(const std::vector<const char *> &vec, const char *value) {
+             for (const char *item : vec) {
+               if (strcmp(item, value) == 0)
+                 return item;
+             }
+             return nullptr;
+           }
+
+           class ClimateDevice {
+            public:
+             void set_custom_fan_modes(std::initializer_list<const char *> modes) {
+               this->custom_fan_modes_ = modes;
+               this->active_custom_fan_mode_ = nullptr;  // Reset when modes change
+             }
+             bool set_custom_fan_mode(const char *mode) {
+               // Find mode in supported list and store that pointer (not the input pointer)
+               const char *validated_mode = vector_find(this->custom_fan_modes_, mode);
+               if (validated_mode != nullptr) {
+                 this->active_custom_fan_mode_ = validated_mode;
+                 return true;

+           };
+           ```
+        2. **Invariant coupling:** When multiple fields must remain synchronized to prevent buffer overflows or data corruption.
+           ```cpp
+           class Buffer {
+            public:
+             void resize(size_t new_size) {
+               auto new_data = std::make_unique<uint8_t[]>(new_size);
+               if (this->data_) {
+                 std::memcpy(new_data.get(), this->data_.get(), std::min(this->size_, new_size));
+               }
+               this->data_ = std::move(new_data);
+               this->size_ = new_size;  // Must stay in sync with data_
+             }
+            private:
+             std::unique_ptr<uint8_t[]> data_;
+             size_t size_{0};  // Must match allocated size of data_
+           };
+           ```
+        3. **Resource management:** When setters perform cleanup or registration operations that derived classes might skip.
+    *   **Provide `protected` accessor methods:** When derived classes need controlled access to `private` members.
+
+*   **C++ Preprocessor Directives:**
+    *   **Avoid `#define` for constants:** Using `#define` for constants is discouraged and should be replaced with `const` variables or enums.
+    *   **Use `#define` only for:**
+        - Conditional compilation (`#ifdef`, `#ifndef`)
+        - Compile-time sizes calculated during Python code generation (e.g., configuring `std::array` or `StaticVector` dimensions via `cg.add_define()`)
+
+*   **C++ Additional Conventions:**
+    *   **Member access:** Prefix all class member access with `this->` (e.g., `this->value_` not `value_`)
+    *   **Indentation:** Use spaces (two per indentation level), not tabs
+    *   **Type aliases:** Prefer `using type_t = int;` over `typedef int type_t;`
+    *   **Line length:** Wrap lines at no more than 120 characters

     *   **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.

+## 8. Public API and Breaking Changes
+
+*   **Public C++ API:**
+    *   **Components**: Only documented features at [esphome.io](https://esphome.io) are public API. Undocumented `public` members are internal.
+    *   **Core/Base Classes** (`esphome/core/`, `Component`, `Sensor`, etc.): All `public` members are public API.
+    *   **Components with Global Accessors** (`global_api_server`, etc.): All `public` members are public API (except config setters).
+
+*   **Public Python API:**
+    *   All documented configuration options at [esphome.io](https://esphome.io) are public API.
+    *   Python code in `esphome/core/` actively used by existing core components is considered stable API.
+    *   Other Python code is internal unless explicitly documented for external component use.
+
+*   **Breaking Changes Policy:**
+    *   Aim for **6-month deprecation window** when possible
+    *   Clean breaks allowed for: signature changes, deep refactorings, resource constraints
+    *   Must document migration path in PR description (generates release notes)
+    *   Blog post required for core/base class changes or significant architectural changes
+    *   Full details: https://developers.esphome.io/contributing/code/#public-api-and-breaking-changes
+
+*   **Breaking Change Checklist:**
+    - [ ] Clear justification (RAM/flash savings, architectural improvement)
+    - [ ] Explored non-breaking alternatives
+    - [ ] Added deprecation warnings if possible (use `ESPDEPRECATED` macro for C++)
+    - [ ] Documented migration path in PR description with before/after examples
+    - [ ] Updated all internal usage and esphome-docs
+    - [ ] Tested backward compatibility during deprecation period
+
+*   **Deprecation Pattern (C++):**
+    ```cpp
+    // Remove before 2026.6.0
+    ESPDEPRECATED("Use new_method() instead. Removed in 2026.6.0", "2025.12.0")
+    void old_method() { this->new_method(); }
+    ```
+
+*   **Deprecation Pattern (Python):**
+    ```python
+    # Remove before 2026.6.0
+    if CONF_OLD_KEY in config:
+        _LOGGER.warning(f"'{CONF_OLD_KEY}' deprecated, use '{CONF_NEW_KEY}'. Removed in 2026.6.0")
+        config[CONF_NEW_KEY] = config.pop(CONF_OLD_KEY)  # Auto-migrate

+            the latest updates.
+
+            Please make sure to update to the latest ESPHome version and

+// CRITICAL ESP32-S3 HARDWARE SHA ACCELERATION REQUIREMENTS:
+//
+// The ESP32-S3 uses hardware DMA for SHA acceleration. The mbedtls_sha256_context structure contains
+// internal state that the DMA engine references. This imposes two critical constraints:
+//
+// 1. NO VARIABLE LENGTH ARRAYS (VLAs): VLAs corrupt the stack layout, causing the DMA engine to
+//    write to incorrect memory locations. This results in null pointer dereferences and crashes.
+//    ALWAYS use fixed-size arrays (e.g., char buf[65], not char buf[size+1]).
+//
+// 2. SAME STACK FRAME ONLY: The SHA256 object must be created and used entirely within the same
+//    function. NEVER pass the SHA256 object or HashBase pointer to another function. When the stack
+//    frame changes (function call/return), the DMA references become invalid and will produce
+//    truncated hash output (20 bytes instead of 32) or corrupt memory.
+//
+// CORRECT USAGE:
+//   void my_function() {
+//     sha256::SHA256 hasher;  // Created locally
+//     hasher.init();
+//     hasher.add(data, len);  // Any size, no chunking needed
+//     hasher.calculate();
+//     bool ok = hasher.equals_hex(expected);
+//     // hasher destroyed when function returns
+//   }
+//
+// INCORRECT USAGE (WILL FAIL ON ESP32-S3):
+//   void my_function() {
+//     sha256::SHA256 hasher;
+//     helper(&hasher);  // WRONG: Passed to different stack frame

+// ===== RAS-2819T PROTOCOL DOCUMENTATION =====
+//
+// The RAS-2819T uses a two-packet IR protocol with some exceptions for simple commands.
+//
+// PACKET STRUCTURE:
+// All packets are 6 bytes (48 bits) transmitted with standard Toshiba timing.
+//
+// TWO-PACKET COMMANDS (Mode/Temperature/Fan changes):
+//
+// First Packet (rc_code_1):  [C2 3D] [FAN_HI FAN_LO] [TEMP] [~TEMP]
+//   Byte 0-1: Header (always 0xC23D)
+//   Byte 2-3: Fan speed encoding (varies by mode, see fan tables below)
+//   Byte 4:   Temperature + mode encoding
+//   Byte 5:   Bitwise complement of temperature byte
+//
+// Second Packet (rc_code_2): [D5] [FAN2] [00] [SUF1] [SUF2] [SUF3]
+//   Byte 0:   Header (always 0xD5)
+//   Byte 1:   Fan speed secondary encoding
+//   Byte 2:   Always 0x00
+//   Byte 3-5: Fixed suffix pattern (depends on fan speed and mode)
+//
+// TEMPERATURE ENCODING:
+// Base temp codes: 18°C=0x10, 19°C=0x30, 20°C=0x20, 21°C=0x60, 22°C=0x70,
+//                  23°C=0x50, 24°C=0x40, 25°C=0xC0, 26°C=0xD0, 27°C=0x90,
+//                  28°C=0x80, 29°C=0xA0, 30°C=0xB0
+// Mode offsets added to base temp:
+//   COOL: No offset
+//   HEAT: +0x0C (e.g., 24°C heat = 0x40 | 0x0C = 0x4C)
+//   AUTO: +0x08 (e.g., 24°C auto = 0x40 | 0x08 = 0x48)
+//   DRY:  +0x24 (e.g., 24°C dry = 0x40 | 0x24 = 0x64)
+//
+// FAN SPEED ENCODING (First packet bytes 2-3):
+//   AUTO: 0xBF40, QUIET: 0xFF00, LOW: 0x9F60, MEDIUM: 0x5FA0, HIGH: 0x3FC0
+//   Special cases: AUTO/DRY modes use 0x1FE0 instead
+//
+// SINGLE-PACKET COMMANDS:
+// Power Off: 0xC23D7B84E01F (6 bytes, no second packet)
+// Swing Toggle: 0xC23D6B94E01F (6 bytes, no second packet)
+//
+// MODE DETECTION (from first packet):
+// - Check bytes 2-3: if 0x7B84 → OFF mode
+// - Check bytes 2-3: if 0x1FE0 → AUTO/DRY/low-temp-COOL (distinguish by temp code)
+// - Otherwise: COOL/HEAT/FAN_ONLY (distinguish by temp code and byte 5)

+// This component uses a dedicated USB task for event processing to prevent data loss.
+// - USB Task (high priority): Handles USB events, executes transfer callbacks, releases transfer slots
+// - Main Loop Task: Initiates transfers, processes device connect/disconnect events
+//
+// Thread-safe communication:
+// - Lock-free queues for USB task -> main loop events (SPSC pattern)
+// - Lock-free TransferRequest pool using atomic bitmask (MCMP pattern - multi-consumer, multi-producer)
+//
+// TransferRequest pool access pattern:
+// - get_trq_() [allocate]: Called from BOTH USB task and main loop threads
+//   * USB task: via USB UART input callbacks that restart transfers immediately
+//   * Main loop: for output transfers and flow-controlled input restarts
+// - release_trq() [deallocate]: Called from BOTH USB task and main loop threads
+//   * USB task: immediately after transfer callback completes (critical for preventing slot exhaustion)
+//   * Main loop: when transfer submission fails
+//
+// The multi-threaded allocation/deallocation is intentional for performance:
+// - USB task can immediately restart input transfers and release slots without context switching
+// - Main loop controls backpressure by deciding when to restart after consuming data
+// The atomic bitmask ensures thread-safe allocation/deallocation without mutex blocking.

-// Helper function for WiFi scan result comparison
-// Returns true if 'a' should be placed before 'b' in the sorted order
+/// Comparator for WiFi scan result sorting - determines which network should be tried first
+/// Returns true if 'a' should be placed before 'b' in the sorted order (a is "better" than b)
+///
+/// Sorting logic (in priority order):
+/// 1. Matching networks always ranked before non-matching networks
+/// 2. For matching networks: Priority first (CRITICAL - tracks failure history)
+/// 3. RSSI as tiebreaker for equal priority or non-matching networks
+///
+/// WHY PRIORITY MUST BE CHECKED FIRST:
+/// The priority field tracks connection failure history via priority degradation:
+/// - Initial priority: 0.0 (from config or default)
+/// - Each connection failure: priority -= 1.0 (becomes -1.0, -2.0, -3.0, etc.)
+/// - Failed BSSIDs sorted lower → naturally try different BSSID on next scan
+///
+/// This enables automatic BSSID cycling for various real-world failure scenarios:
+/// - Crashed/hung AP (visible but not responding)
+/// - Misconfigured mesh node (accepts auth but no DHCP/routing)
+/// - Capacity limits (AP refuses new clients)
+/// - Rogue AP (same SSID, wrong password or malicious)
+/// - Intermittent hardware issues (flaky radio, overheating)
+///
+/// Example mesh network: 3 APs with same SSID "home", all at priority 0.0 initially
+/// - Try strongest BSSID A (sorted by RSSI) → fails → priority A becomes -1.0
+/// - Next scan: BSSID B and C (priority 0.0) sorted BEFORE A (priority -1.0)
+/// - Try next strongest BSSID B → succeeds or fails and gets deprioritized
+/// - System naturally cycles through all BSSIDs via priority degradation
+/// - Eventually finds working AP or tries all options before restarting adapter
+///
+/// If we checked RSSI first (Bug in PR #9963):
+/// - Same failed BSSID would keep being selected if it has strongest signal
+/// - Device stuck connecting to crashed AP with -30dBm while working AP at -50dBm ignored
+/// - Priority degradation would be useless
+/// - Mesh networks would never recover from single AP failure

+ * Instead of each entity maintaining controller callbacks (32 bytes overhead per entity),
+ * entities call ControllerRegistry::notify_*_update() which iterates the small list

+ * rather than receiving it as callback parameters that were being ignored anyway.
+ *
+ * Memory savings: 32 bytes per entity (2 controllers × 16 bytes std::function overhead)

+ * Large config (80 entities): ~2,540 bytes saved

+PlatformIO output format:

+    Flash: [===       ]  34.0% (used 348511 bytes from 1023984 bytes)

+This script combines multiple component test files that use the same common bus

+The merger handles:
+- Component-specific substitutions (prefixing to avoid conflicts)
+- Multiple instances of component configurations
+- Shared common bus packages (included only once)
+- Platform-specific configurations
+- Uses ESPHome's built-in merge_config for proper YAML merging

+# How to write C++ ESPHome unit tests
+
+1. Locate the folder with your component or create a new one with the same name as the component.
+2. Write the tests. You can add as many `.cpp` and `.h` files as you need to organize your tests.
+
+**IMPORTANT**: wrap all your testing code in a unique namespace to avoid linker collisions when compiling
+testing binaries that combine many components. By convention, this unique namespace is `esphome::component::testing`
+(where "component" is the component under test), for example: `esphome::uart::testing`.
+
+
+## Running component unit tests
+
+(from the repository root)
+```bash
+./script/cpp_unit_test.py component1 component2 ...
+```
+
+The above will compile and run the provided components and their tests.
+
+To run all tests, you can invoke `cpp_unit_test.py` with the special `--all` flag:
+
+```bash
+./script/cpp_unit_test.py --all
+```
+
+To run a specific test suite, you can provide a Google Test filter:
+
+```bash
+GTEST_FILTER='UART*' ./script/cpp_unit_test.py uart modbus
+```
+
+The process will return `0` for success or nonzero for failure. In case of failure, the errors will be printed out to the console.

+### Helper Utilities
+
+#### InitialStateHelper (`state_utils.py`)
+
+The `InitialStateHelper` class solves a common problem in integration tests: when an API client connects, ESPHome automatically broadcasts the current state of all entities. This can interfere with tests that want to track only new state changes triggered by test actions.
+
+**What it does:**
+- Tracks all entities (except stateless ones like buttons)
+- Swallows the first state broadcast for each entity
+- Forwards all subsequent state changes to your test callback
+- Provides `wait_for_initial_states()` to synchronize before test actions
+
+**When to use it:**
+- Any test that triggers entity state changes and needs to verify them
+- Tests that would otherwise see duplicate or unexpected states
+- Tests that need clean separation between initial state and test-triggered changes
+
+**Implementation details:**
+- Uses `(device_id, key)` tuples to uniquely identify entities across devices
+- Automatically excludes `ButtonInfo` entities (stateless)
+- Provides debug logging to track state reception (use `--log-cli-level=DEBUG`)
+- Safe for concurrent use with multiple entity types
+
+**Future work:**
+Consider converting existing integration tests to use `InitialStateHelper` for more reliable state tracking and to eliminate race conditions related to initial state broadcasts.
+
 ### Writing Tests
 
 The simplest way to write a test is to use the `run_compiled` and `api_client_connected` fixtures:

 ##### State Subscription Pattern

+**Recommended: Using InitialStateHelper**

+"""Integration test for script.wait during on_boot (issue #12043).
+
+This test verifies that script.wait works correctly when triggered from on_boot.
+The issue was that ScriptWaitAction::setup() unconditionally disabled the loop,
+even if play_complex() had already been called (from an on_boot trigger at the
+same priority level) and enabled it.
+
+The race condition occurs because:
+1. on_boot's default priority is 600.0 (setup_priority::DATA)
+2. ScriptWaitAction's default setup priority is also DATA (600.0)
+3. When they have the same priority, if on_boot runs first and triggers a script,
+   ScriptWaitAction::play_complex() enables the loop
+4. Then ScriptWaitAction::setup() runs and unconditionally disables the loop
+5. The wait never completes because the loop is disabled
+
+The fix adds a conditional check (like WaitUntilAction has) to only disable the
+loop in setup() if num_running_ is 0.

+# Common Bus Configurations for Component Tests
+
+This directory contains standardized bus configurations (I2C, SPI, UART, Modbus, BLE) that component tests use, enabling multiple components to be tested together with intelligent grouping.
+
+## Purpose
+
+These common configs allow multiple components to **share a single bus**, dramatically reducing CI time by compiling multiple compatible components together. Components with identical bus configurations are automatically grouped and tested together.
+
+## Structure
+
+```

+    └── esp32-c3-idf.yaml
+```
+
+## How It Works
+
+### Component Test Structure
+Each component test includes the common bus config:
+
+```yaml
+# tests/components/bh1750/test.esp32-idf.yaml
+packages:
+  i2c: !include ../../test_build_components/common/i2c/esp32-idf.yaml
+
+<<: !include common.yaml
+```
+
+The common config provides:
+- Standardized pin assignments
+- A shared bus instance (`i2c_bus`, `spi_bus`, `uart_bus`, `modbus_bus`, etc.)
+
+The component's `common.yaml` references the shared bus:
+```yaml
+# tests/components/bh1750/common.yaml
+sensor:
+  - platform: bh1750
+    i2c_id: i2c_bus
+    name: Living Room Brightness
+    address: 0x23
+```
+
+### Intelligent Grouping (Implemented)
+Components with identical bus configurations are automatically grouped and tested together:
+
+```yaml
+# Auto-generated merged config (created by test_build_components.py)
+packages:
+  i2c: !include ../../test_build_components/common/i2c/esp32-idf.yaml
+
+sensor:
+  - platform: bme280_i2c
+    i2c_id: i2c_bus
+    temperature:
+      name: BME280 Temperature
+  - platform: bh1750
+    i2c_id: i2c_bus
+    name: BH1750 Illuminance
+  - platform: sht3xd
+    i2c_id: i2c_bus
+    temperature:
+      name: SHT3xD Temperature
+```
+
+**Result**: 3 components compile in one test instead of 3 separate tests!
+
+### Package Dependencies
+Some packages include other packages to avoid duplication:
+
+```yaml
+# tests/test_build_components/common/modbus/esp32-idf.yaml
+packages:
+  uart: !include ../uart/esp32-idf.yaml  # Modbus requires UART
+
+substitutions:
+  flow_control_pin: GPIO4
+
+modbus:
+  - id: modbus_bus
+    uart_id: uart_bus
+    flow_control_pin: ${flow_control_pin}
+```
+
+Components using `modbus` packages automatically get `uart` as well.
+
+## Pin Allocations
+
+### I2C (Standard - 50kHz)
+- **ESP32 IDF**: SCL=GPIO16, SDA=GPIO17
+- **ESP32 Arduino**: SCL=GPIO22, SDA=GPIO21
+- **ESP32-C3**: SCL=GPIO5, SDA=GPIO4
+- **ESP32-S2/S3**: SCL=GPIO9, SDA=GPIO8
+- **ESP8266**: SCL=GPIO5, SDA=GPIO4
+- **RP2040**: SCL=GPIO5, SDA=GPIO4
+- **BK72xx**: SCL=P20, SDA=P21
+
+### I2C Low Frequency (10kHz)
+Same pin allocations as standard I2C, but with 10kHz frequency for components requiring slower speeds.
+
+### SPI
+- **ESP32**: CLK=GPIO18, MOSI=GPIO23, MISO=GPIO19
+- **ESP32-C3**: CLK=GPIO6, MOSI=GPIO7, MISO=GPIO5
+- **ESP32-S2**: CLK=GPIO36, MOSI=GPIO35, MISO=GPIO37
+- **ESP32-S3**: CLK=GPIO40, MOSI=GPIO6, MISO=GPIO41
+- **ESP8266**: CLK=GPIO14, MOSI=GPIO13, MISO=GPIO12
+- **RP2040**: CLK=GPIO18, MOSI=GPIO19, MISO=GPIO16
+- CS pins are component-specific (each SPI device needs unique CS)
+
+### UART
+- **ESP32 IDF**: TX=GPIO17, RX=GPIO16 (baud: 19200)
+- **ESP32-C3 IDF**: TX=GPIO7, RX=GPIO6 (baud: 19200)
+- **ESP8266**: TX=GPIO1, RX=GPIO3 (baud: 19200)
+- **RP2040**: TX=GPIO0, RX=GPIO1 (baud: 19200)
+
+### Modbus (includes UART)
+Same UART pins as above, plus:
+- **flow_control_pin**: GPIO4 (all platforms)
+
+### BLE
+- **ESP32**: Shared `esp32_ble_tracker` infrastructure
+- Each component defines unique `ble_client` with different MAC addresses
+
+## Benefits
+
+1. **Shared bus = less duplication**
+   - 200+ I2C components use common bus configs
+   - 60+ SPI components use common bus configs
+   - 80+ UART components use common bus configs
+   - 6 Modbus components use common modbus configs (which include UART)
+
+2. **Intelligent grouping reduces CI time**
+   - Components with identical bus configs are automatically grouped
+   - Typical reduction: 80-90% fewer builds
+   - Example: 3 I2C components → 1 merged build (saves 2 builds)
+   - CI runs 5 component batches in parallel (configurable via `max-parallel` in `.github/workflows/ci.yml`)
+
+3. **Easier maintenance**
+   - Change bus pins for a platform once, affects all component tests
+   - Consistent pin assignments across all components
+   - Centralized bus configuration
+
+## Component Compatibility
+
+### Groupable Components
+Components are automatically grouped when they have:
+- Identical bus package references (e.g., all use `i2c/esp32-idf.yaml`)
+- No local file references (`$component_dir`)
+- No `!extend` or `!remove` directives
+- Proper bus ID references (`i2c_id: i2c_bus`, `spi_id: spi_bus`, etc.)
+
+### Non-Groupable Components
+Components tested individually when they:
+- Use different bus frequencies (e.g., `i2c` vs `i2c_low_freq`)
+- Reference local files with `$component_dir`
+- Are platform components (abstract base classes with `IS_PLATFORM_COMPONENT = True`)
+- Define buses directly (not migrated to packages yet)
+- Are in `ISOLATED_COMPONENTS` list (known build conflicts)
+
+### Bus Variants
+- **i2c** (50kHz): Standard I2C frequency for most sensors
+- **i2c_low_freq** (10kHz): For sensors requiring slower I2C speeds
+- **modbus**: Includes UART via package dependencies
+
+### Making Components Groupable
+
+**WARNING**: Using `!extend` or `!remove` directives in component test files prevents automatic component grouping in CI, making builds slower.
+
+When platform-specific parameters are needed, inline the full configuration rather than using `!extend` or `!remove`. This allows the component to be grouped with other compatible components, reducing CI build time.
+
+**Note**: Some components legitimately require `!extend` or `!remove` for platform-specific features (e.g., `adc` removing ESP32-only `attenuation` parameter on ESP8266). These are correctly identified as non-groupable.
+
+## Testing Components
+
+### Testing Individual Components
+Test specific components using `test_build_components`:
+```bash
+# Test a single component
+./script/test_build_components -c bme280_i2c -t esp32-idf -e config
+
+# Test multiple components
+./script/test_build_components -c bme280_i2c,bh1750,sht3xd -t esp32-idf -e compile
+```
+
+### Testing All Components Together
+To verify that all components can be tested together without ID conflicts or configuration issues:
+```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. This is useful for:
+- Detecting ID conflicts between components
+- Validating that components can coexist in the same configuration
+- Ensuring proper `i2c_id`, `spi_id`, `uart_id` specifications
+
+Use `-e config` for fast configuration validation, or `-e compile` for full compilation testing.
+
+### Testing Component Groups
+Test specific groups of components by bus signature:
+```bash
+# Test all I2C components together
+./script/test_component_grouping.py -s i2c -e config
+
+# Test with custom group sizes
+./script/test_component_grouping.py --min-size 5 --max-size 20 --max-groups 3
+```
+
+## Implementation Details
+
+### Scripts
+- `script/analyze_component_buses.py`: Analyzes components to detect bus usage and grouping compatibility
+- `script/merge_component_configs.py`: Merges multiple component configs into a single test file
+- `script/test_build_components.py`: Main test runner with intelligent grouping
+- `script/test_component_grouping.py`: Test component groups or all components together
+- `script/split_components_for_ci.py`: Splits components into batches for parallel CI execution
+
+### Configuration
+- `.github/workflows/ci.yml`: CI workflow with `max-parallel: 5` for component testing
+- Package dependencies defined in `PACKAGE_DEPENDENCIES` (e.g., modbus → uart)
+- Base bus components excluded from migration warnings: `i2c`, `spi`, `uart`, `modbus`, `canbus`
