Implemented device-to-outlet mapping API with the following endpoints: ## New Endpoints 1. **GET /api/devices/{id}/outlets** - List all outlets mapped to a device 2. **POST /api/devices/{id}/outlets** - Assign outlets to a device (accepts list of outlet_ids) 3. **DELETE /api/devices/{id}/outlets/{outlet_id}** - Remove an outlet mapping from a device 4. **POST /api/devices/{id}/power/{action}** - Control power (on/off/reboot) for all outlets mapped to a device ## Implementation Details - Added schemas in app/api/schemas.py:155-197 - Added endpoints in app/api/config_router.py:294-548 - Validates outlet IDs are in range 1-24 - Prevents assigning same outlet to multiple devices (409 Conflict) - Requires confirmation for power operations (confirm: true) - Handles SNMP timeouts and errors gracefully (503 Service Unavailable) - Cascade deletes outlet mappings when device is deleted ## Testing - Added 24 new tests in tests/test_config_api.py - All 139 tests pass (56 in test_config_api.py alone) - Tests cover: success cases, validation, conflicts, cascades, SNMP error handling ## QA Verification Can assign device to outlets 1,2,3,4 and power on/off all at once as specified in acceptance criteria.
