Integration diagnostics	Diagnostics

Integrations can provide diagnostics to help the user gather data to aid in troubleshooting. Diagnostics can be provided for config entries but also individually for each device entry.

Users can download config entry diagnostics from the config entry options menu, on the integration page. For device diagnostics, users can download them from the device info section (or from its menu, depending on the integration). Note that if an integration does not implement device diagnostics, the device page will provide config entry diagnostics.

:::warning It is critical to ensure that no sensitive data is exposed. This includes but is not limited to:

• Passwords and API keys
• Authentication tokens
• Location data
• Personal information

Home Assistant provides the async_redact_data utility function which you can use to safely remove sensitive data from the diagnostics output. :::

The following is an example on how to implement both config entry and device entry diagnostics:

TO_REDACT = [
    CONF_API_KEY,
    APPLIANCE_CODE
]

async def async_get_config_entry_diagnostics(
    hass: HomeAssistant, entry: MyConfigEntry
) -> dict[str, Any]:
    """Return diagnostics for a config entry."""

    return {
        "entry_data": async_redact_data(entry.data, TO_REDACT),
        "data": entry.runtime_data.data,
    }

async def async_get_device_diagnostics(
    hass: HomeAssistant, entry: MyConfigEntry, device: DeviceEntry
) -> dict[str, Any]:
    """Return diagnostics for a device."""
    appliance = _get_appliance_by_device_id(hass, device.id)
    return {
        "details": async_redact_data(appliance.raw_data, TO_REDACT),
        "data": appliance.data,
    }

An integration can provide both types of diagnostics or just one of them.
