Smoke detector Netatmo NSA-DE — photoelectric reflection, battery 10‑year, 85 dB, wireless (Wi‑Fi 2.4 GHz)

The Netatmo NSA-DE Smart Smoke Detector is a wireless, photoelectric reflection smoke alarm designed for home use. It emits an 85 dB alarm when smoke is detected and can send real-time alerts to your smartphone and family members via Wi‑Fi, while functioning as a standalone detector if Wi‑Fi is not configured. The unit is battery powered with an advertised 10‑year battery life and a compact form factor with a diameter of 115 mm and depth of 44 mm.

Advantages

The detector combines local audible protection with remote smartphone alerts through the Netatmo app, allowing you to be notified even when away from home. It uses photoelectric reflection sensing, which is effective at detecting smoldering fires, and supports interconnection and Bluetooth Low Energy for setup. The device requires only a 2.4 GHz Wi‑Fi connection for full app functionality and does not require a subscription to use the mobile app or online access.

Suitable for

• Residential homes and apartments where early smoke detection is needed
• Rooms prone to smoldering fires such as bedrooms and living rooms
• Users who want remote smartphone alerts and app control

When it may not be suitable

This alarm requires a high‑speed 2.4 GHz Wi‑Fi network for smartphone notifications and remote features; public Wi‑Fi hotspots are not supported. While the detector will sound locally without Wi‑Fi, you will not receive remote alerts or use remote hush and test functions without a compatible Wi‑Fi connection and supported mobile device.

How to use

Install the detector on a ceiling or high on a wall using the supplied mount, screws and anchors. Configure the device with the Netatmo mobile app over a 2.4 GHz Wi‑Fi network and Bluetooth Low Energy during setup to enable smartphone alerts and remote features. The detector will sound an 85 dB alarm automatically when smoke is detected even if Wi‑Fi is not configured; however, smartphone notifications and remote hush/test require a configured Wi‑Fi connection and a compatible smartphone or web browser.

What to consider before purchase

• Ensure you have a reliable 2.4 GHz Wi‑Fi network at the installation location
• Check your smartphone meets app requirements (iOS 10+/Android 5.0+ with BLE)
• Verify that remote hush and test features require the mobile app and are limited in the Webapp

Usage recommendations

Place the detector on the ceiling in central areas or high on walls away from vents, fans and cooking appliances to reduce false alarms; test the device after installation and follow local regulations for smoke alarm placement and maintenance.
