Error message

connection_error

What it means

Raised by the bosch_alarm set_panel_date service when panel.set_panel_date(value) fails with asyncio.InvalidStateError. In the bosch_alarm library this surfaces when the panel's connection state is inconsistent (futures already done/cancelled because the session died), i.e. the cached runtime panel object no longer has a live connection. The HomeAssistantError carries translation_key 'connection_error' with the panel title as placeholder.

Solutions

1. Confirm the integration entry state is Loaded (not SetupRetry/Failed) before calling the service.
2. Reload the bosch_alarm integration to re-establish the panel connection, then re-run the service.
3. Restore panel network reachability (see cannot_connect triage) so the connection stays healthy.

entry = hass.config_entries.async_get_entry(entry_id)
if entry.state is not ConfigEntryState.LOADED:
    raise ServiceValidationError("panel_not_connected")  # check before calling service

try:
    await panel.set_panel_date(value)
except asyncio.InvalidStateError as err:
    raise HomeAssistantError(translation_domain=DOMAIN, translation_key="connection_error", ...) from err

When it happens

Trigger: Calling the bosch_alarm.set_panel_date service while the panel entry is in a retry/failed state, right after a network drop, or when the coordinator hasn't reconnected yet.

Common situations: Panel briefly offline; service invoked during entry setup retries; stale runtime_data after a disconnect event.
