# Project issues

General issues are listed at
<https://github.com/project-chip/connectedhomeip/issues> .

In order to be able to effectively follow up on these issues, they are separated
into groups for further review and fixing based on current maintainers on
specific areas of the code. The separation is done via `labels`.

Issues that still need triaging are labeled as `needs triage`:

<https://github.com/project-chip/connectedhomeip/issues?q=is%3Aissue+is%3Aopen+label%3A%22needs+triage%22>

## Non-SDK issues

In some cases the issue is integrating with ecosystems or environments are not
supported. In these cases, issues can be re-directed to specific support pages
rather than the SDK GitHub issues.

### Google Integration

-   General integration link: <https://developers.home.google.com/matter>
-   Support via the communities areas:
    -   Stack overflow:
        <https://stackoverflow.com/questions/tagged/google-smart-home>
    -   Google Nest Community:
        <https://www.googlenestcommunity.com/t5/Smart-Home-Developer-Forum/bd-p/Smart-Home-Developer-Forum>

### Apple Integration

This applies if there is an issue with Home interacting with a device (as
opposed to an issue with Matter.framework or the SDK that is encountered by code
actually running on darwin).

General instructions available at [here](./guides/darwin.md) in the
`Providing feedback to Apple` section.

Once a Feedback Assistant ticket is filed, the ticket ID can be sent to Boris
Zbkarsky to ensure it is noticed by the right people

### Environments not currently supported / not maintained

Some items are explicitly not maintained currently

-   Windows integration: no official maintainer for this so currently not
    supported
-   Old compiler support: CHIP requires a C++17 or higher compiler.

## Platform maintainers

This level of separation is generally for platform-specific issues (e.g. failure
to commission for one specific platform, failure to run on some specific
operating system).

Contact is generally done on slack. E-mail addresses are not added here on
purpose in order to avoid spam.

## Example maintenance

Examples often correspond to specific device types. We have split the contact
per device type regardless of example (e.g. all-clusters will contain all device
types or functionality) as well as individual examples.
