8-8: Consider adding a screenshot of the menu path.Adding a screenshot showing the path to Settings > Repairs > System information would help users locate this feature more easily.
22-30: Add guidance on error handling and common pitfalls.The example would be more robust with additional guidance on:
- Error handling for when no config entries exist
- Handling multiple config entries
- Exception handling for network failures
Here's a more comprehensive example:
async def system_health_info(hass: HomeAssistant) -> dict[str, Any]: """Get info for the info page.""" entries = hass.config_entries.async_entries(DOMAIN) if not entries: return { "setup_state": "no_entries", "documentation": "https://www.home-assistant.io/integrations/example" } # Use the primary entry if multiple exist config_entry = entries[0] try: can_reach = await system_health.async_check_can_reach_url( hass, ENDPOINT, timeout=3 ) except Exception as err: # pylint: disable=broad-except can_reach = f"Failed to connect: {err}" return { "can_reach_server": can_reach, "remaining_requests": config_entry.runtime_data.requests_remaining, "setup_state": "configured" }
32-34: Enhance the helper function documentation.Consider adding more details about
async_check_can_reach_url:
- Available parameters (e.g., timeout)
- Return type
- Exception handling
37-46: Add translation naming conventions.Consider adding guidelines for:
- Key naming conventions (e.g., using snake_case)
- Best practices for writing clear, translatable descriptions
- How to handle dynamic values in translations
37-37: Simplify wording.Replace "In order to provide" with "To provide" for better conciseness.

1-4: YAML Front Matter is Correctly Formatted
The front matter (lines 1–4) is well-formed with a proper title and sidebar label. This matches the convention used elsewhere in the documentation.
6-9: Introduction Clarity & Module Reference
The introduction (lines 6–9) clearly explains the purpose of the system health platform. However, as suggested in previous reviews, consider clarifying that the referenced file,system_health.py, is the specific platform module responsible for handling these callbacks.
10-13: Instruction on Adding thesystem_health.pyFile
The instruction at lines 10–13 correctly directs users to add asystem_health.pyfile and implement theasync_registermethod. To further improve clarity, you might include a brief note on the role or location of this file within the integration structure (as per earlier feedback).
14-24:async_registerSnippet is Well-Structured
The Python code snippet (lines 14–24) for theasync_registerfunction is concise and follows best practices (e.g., proper import order and use of the@callbackdecorator). The inline documentation is helpful.
28-40: Async Info Callback Implementation
Thesystem_health_infofunction (lines 28–40) demonstrates clear asynchronous behavior and accurately returns a mixed-type dictionary. The inline comment on line 37 about setting a coroutine (instead of awaiting it) is useful for readers to understand that the frontend handles pending results. You might consider a brief note explaining when an explicit await might be necessary in different contexts, although this design is intentional here.
42-45: Helpful Tip on theasync_check_can_reach_urlHelper
The tip block (lines 42–45) effectively highlights the purpose of theasync_check_can_reach_urlhelper. It reinforces its non-blocking nature and guides users on how to integrate it into their system health callbacks.

6-8: Clarify Platform Module Naming.
While the instructions mention adding asystem_health.pyfile in line 12, it may be beneficial to reiterate at the introduction that the file must be named exactlysystem_health.pyto avoid any ambiguity for the integrator.
14-24: Include Additional Import Guidance in Code Snippet.
Theasync_registercode snippet is well presented. However, since later examples use types such asAny(in the return type) or refer to placeholders likeExampleConfigEntry, it might help to include a comment or additional import (e.g.,from typing import Any) to ensure completeness for integrators who copy these snippets.
26-40: Clarify Placeholder Identifiers in the Callback Example.
Thesystem_health_infofunction example is clear; however, identifiers likeExampleConfigEntry,DOMAIN, andENDPOINTare used without explanation. Consider adding inline comments or notes indicating these are placeholders that should be replaced with the actual integration-specific values.
47-57: Improve Language Consistency in Translation Instructions.
The instruction "Translate each key on the info dictionary using thesystem_healthsection onstrings.jsonfile" can be reworded for clarity. Consider revising it to "Translate each key on the info dictionary using thesystem_healthsection in thestrings.jsonfile" to improve grammatical precision.🧰 Tools

1-4: Front Matter is Correct but Consider Additional Metadata.
The YAML front matter is structured correctly. You may consider adding extra metadata (e.g., a description or authors field) to provide more context if required by the project guidelines.
10-12: Introduction Clarity and Importance of Naming.
The introduction clearly explains the purpose of the system health platform. Consider briefly explaining why the precise naming (i.e.system_health.py) is critical, or linking to further guidelines, to reinforce best practices.
42-44: Tip Block is Informative.
The tip block effectively explains the purpose ofasync_check_can_reach_url. It aids in understanding and requires no change.
