  "question": "Which convertible car seats have sensors that send alerts to a phone when the harness comes loose or a child is unbuckled?",
  "answer": "Evenflo Revolve360 Slim 2-in-1 Rotating Car Seat with SensorSafe: SensorSafe alerts in real time over Bluetooth to four potentially unsafe conditions: unsafe ambient temperature, child unattended, child buckled too long, and unexpected chest clip unbuckling.\nCYBEX Sirona M SensorSafe 2.0: SensorSafe can alert a smartphone when a buckled child remains after shutdown, the clip opens during travel, rear-seat temperature is uncomfortable or sitting time is extended; alerts may escalate to emergency contacts with GPS coordinates.\nCybex Sirona S SensorSafe: The Bluetooth chest clip can alert the app when it is unbuckled, the rear seat becomes too hot or cold, or the driver leaves the child behind.\nCYBEX Eternis S SensorSafe: The chest clip can alert the phone app about unbuckling, temperature, and periods of inactivity.\nCybex Gold Eternis S Sensor Safe All-In-One Car Seat: The video demonstrates the SensorSafe OBD receiver and app alerts for temperature, an unbuckled chest clip, and a child left in the car with location shown. It also shows the three-position reclining headrest and several colour options.\nCybex Callisto G 360: Reports the SensorSafe chest clip links to a phone app that warns about unbuckling, unsafe temperature and leaving a child behind.",
