Netatmo Smarter smoke detector set of 3

The Smart Smoke Detector is a photoelectric (optical) smoke detector that increases the security of your home. When a fire breaks out and the powerful 85 dB alarm is triggered, the Smart Smoke Detector sends this alarm directly to your smartphone in real time.

Unlike conventional smoke detectors, the Smart Smoke Detector takes this worry off your shoulders by sending real-time alerts to your smartphone and your family members as soon as smoke is detected. Simply install the wireless Smart Smoke Detector on the ceiling in every bedroom, nursery and hallway, download the app and protect your home from fires. It's simple.
