Review: Mi hanno salvato la porta blindata! - Cercavo un sistema di allarme Smart che avesse dei contatti porta/finestra con sensore a vibrazione e questo articolo è il migliore tra quelli provati, motivo per il quale ho deciso di acquistare tutto il sistema Bosch. Ho fatto la prova sulla porta blindata ma avendo subito un primo tentativo di effrazione mediante manomissione di uno dei due cilindri ho provato diverse posizioni non badando alle indicazioni di montaggio suggerite dal produttore. Dopo vari test ho installato il sensore tra le due serrature: alla massima sensibilità percepisce la vibrazione prodotta da una prima mandata “delicata” con chiave quindi molto molto sensibile. Hanno tentato nuovamente una effrazione ma questa volta, essendo scattato subito l’allarme, non hanno danneggiato la porta blindata motivo per il quale, contrariamente al buon senso ho deciso di installare un secondo sensore nella posizione indicata dal costruttore (quella classica in alto) … così per abbondare visto che il costo per riparare una porta blindata ė decisamente superiore a quello di un sensore meglio avere un sensore di backup. Per me super consigliato Review: Top Artikel - Einfache an zu bringen, der kleber ist sehr fest, ich habe keine Angst das es abfallen würde. Hat sofort einwandfrei funktioniert und einfache Installation mit der App. ## Features - Smart sensor: reliably detects open doors, windows and vibrations, shows their status in the app and serves as a trigger for actions and scenarios in the Smart home thanks to the integrated button - Break-in protection: once integrated into the Bosch Smart Home alarm system, the door/window contact triggers an alarm when it detects vibrations at the window caused by break-in attempts - Warning in the alarm system: door/window sensor detects security gaps when the alarm system is activated and draws your attention to open doors and windows - Save heating costs: window sensor detects open windows, enabling the smart radiator thermostats to be automatically turned down via the "Sustainable ventilation" service to save energy costs - Maximum added value in the system: you need a Bosch Smart Home controller or Bosch Smart Home controller II to integrate the device into your Bosch Smart Home system - Box contents: 1x door/window sensor, 1x magnet with 2 spacers, 1x CR123A battery, adhesive tape, user manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBLZ8JGL | | Best Sellers Rank | 192,328 in DIY & Tools ( See Top 100 in DIY & Tools ) 164 in Home Security Door & Window Sensors | | Brand | Bosch | | Country Of Origin | China | | Customer Reviews | 4.6 out of 5 stars 311 Reviews | | EU Spare Part Availability Duration | 1 Years | | Global Trade Identification Number | 04062321542566 | | Included Components | 1x door/window sensor, 1x magnet with 2 spacers, 1x CR123A battery, adhesive tape, user manual | | Item Dimensions | 25 x 22 x 75 millimetres | | Item Type Name | Smart Home door/window contact II plus, break-in protection with smart sensor for vibration detection, compatible with Amazon Alexa and Google Assistant, | | Item Weight | 0.05 Kilograms | | Item dimensions L x W x H | 25 x 22 x 75 millimetres | | Item weight | 0.05 Kilograms | | Manufacturer | Bosch | | Manufacturer Part Number | 8750002092 | | Material | Metal | | Maximum Supply Voltage | 3 Volts | | Maximum supply voltage | 3 Volts | | Model Number | 8750002092 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Output Type | Digital | | Response Time | 5 seconds | | Sensing Distance | 2 Metres | | Specific Uses For Product | Door and window security, energy saving, integration into smart home systems | | Style | Door/window Contact II plus | | Style Name | Door/window Contact II plus | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Brand:** Bosch - **Item dimensions L x W x H:** 25 x 22 x 75 millimetres - **Item weight:** 0.05 Kilograms - **Material:** Metal - **Style:** Door/window Contact II plus ## Images ![Smart Home door/window contact II plus, break-in protection with smart sensor for vibration detection, compatible with Amazon Alexa and Google Assistant, white - Image 1](https://m.media-amazon.com/images/I/41oax0w89YL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Hi, does this work with HomeKit?** A: Dear Syl, yes it works with Apple HomeKit.
