It offers real-time audible and smartphone alerts, escape route illumination, live camera activation during emergencies, and advanced dust compensation to reduce false alarms. With a 5-year replaceable battery and easy installation, it’s designed for proactive, connected fire safety. ## Description From the manufacturer Smart alarm If smoke develops, the smoke alarm alerts you audibly on site and via the app if you’re not home. Maximum fire safety Integrated into the alarm system, the smoke detector triggers the illumination of the escape routes and a camera live feed when it detects smoke. Smart break-in protection As part of the alarm system, it also reliably informs and alerts you if there’s a break-in. Dust compensation Minimises false alarms caused by natural house dust and dirt, thanks to the low degree of soiling in the smoke chamber. Prefect all-round protection Alarm in case of fire The interlinked smoke alarm reliably alerts you straight away if smoke develops using the sirens on site. If there’s a fire, it forwards the signal to all integrated smoke alarms and Twinguards. The smoke detector also informs you when you’re out via push notification on your smartphone. All you need to do to call the fire brigade is tap the emergency call button on the app screen. Reliable protection Alarm in case of a break-in Once integrated in the Bosch Smart Home alarm system, the smoke detector also reliably informs you of a break-in via the sirens and scares off unwanted guests.

This happens acoustically via the sirens on site and is forwarded to all smoke detectors and Twinguards. When combined with other interlinked devices, the smoke detector offers even more safety. Integrated lamps illuminate the escape route in an emergency and the shutters are rolled up to open exits. At the same time, smart cameras in your home are activated so that you can visually check the cause of the alarm, even if you’re not at home. Review: Bosch Smart Home Warnung - Bisjetzt funktioniert alles super Review: Zu Teuer, Controller + App fast nutzlos - Die App kann nichts, außer sehr schlecht anzeigen, ob eine Verbindung zum Controller besteht oder nicht. Man kann nicht sehen, wie der Batteriestatus ist. Außerdem haben die Rauchmelder auch sonst keine Sensoren wie Temperatur oder Luftfeuchte, die den Preis rechtfertigen würden. Die Reichweite des Controllers bzw. der Rauchmelder um miteinander zu kommunizieren ist auch sehr schlecht. Ein Stockwerk und nur eine Tür reichen schon aus, dass die Kommunikation abbricht und der Rauchmelder ständig rot blinkt. Ich warte jetzt noch, bis es die neue Fritzbox mit Zigbee Unterstützung gibt, mit der kann ich die Rauchmelder auch einbinden und kann auf den Controller komplett verzichten. Den Controller verkaufe ich dann auf e-bay. 2-Sterne: - Man kann einen Verbindungstest machen (Nutzlos wenn im nächsten Augenblick die Verbindung wieder abreißt), aber man hat zumindest einen Anhaltspunkt. - Testton per App ist möglich ## Features - Central control unit: Connects Bosch Smart Home devices and selected partner devices via the Zigbee wireless protocol and is ready for the international smart home standard matter - Smart Alarm: if it detects smoke, the smoke detector alerts you on site via alarms and on the app when you’re out via push notification on your smartphone - Smoke Detector II, Set of 3 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C4FWZCF8 | | Alarm | Visual | | Best Sellers Rank | 51,309 in DIY & Tools ( See Top 100 in DIY & Tools ) 139 in Smoke Alarms | | Brand | Bosch | | Compatible Devices | Smartphone | | Compatible devices | Smartphone | | Customer Reviews | 4.3 out of 5 stars 5 Reviews | | Power source | Battery Powered | | Product Style | Smoke Detector II, Set of 3 | | Sensor Type | Ionization | | Sensor type | Ionization | | Style | Smoke Detector II, Set of 3 | ## Product Details - **Alarm:** Visual - **Brand:** Bosch - **Compatible devices:** Smartphone - **Power source:** Battery Powered - **Sensor type:** Ionization - **Style:** Smoke Detector II, Set of 3 ## Images ![Bosch Smart Home Fire Warning Set, 3x Smoke Detector II, 1x Controller II - Image 1](https://m.media-amazon.com/images/I/51j6EDWcDrL.jpg) ![Bosch Smart Home Fire Warning Set, 3x Smoke Detector II, 1x Controller II - Image 2](https://m.media-amazon.com/images/I/41BliVPL0eL.jpg) ![Bosch Smart Home Fire Warning Set, 3x Smoke Detector II, 1x Controller II - Image 3](https://m.media-amazon.com/images/I/61spGdJDXQL.jpg) ![Bosch Smart Home Fire Warning Set, 3x Smoke Detector II, 1x Controller II - Image 4](https://m.media-amazon.com/images/I/51oQBp5WxAL.jpg) ![Bosch Smart Home Fire Warning Set, 3x Smoke Detector II, 1x Controller II - Image 5](https://m.media-amazon.com/images/I/71KX89WXYXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bosch Smart Home Warnung *by A***X on 9 April 2026* Bisjetzt funktioniert alles super ### ⭐⭐ Zu Teuer, Controller + App fast nutzlos *by C***I on 2 April 2024* Die App kann nichts, außer sehr schlecht anzeigen, ob eine Verbindung zum Controller besteht oder nicht.
