## Description

SwitchBot Door Alarm Contact Sensor - Smart Home Security Wireless Window Alarm and Door Sensor, Add SwitchBot Hub to Make it Compatible with Alexa: desertcart.com: Tools & Home Improvement

Review: Quick, easy, reliable - These lil fellers are FANTASTIC. Motion sensor + door state functionality in one box is great. Home Assistant integration is fast and easy. Latency is non-existent. Can't say enough good things.
Review: ⭐️⭐️⭐️⭐️⭐️ Simple, Reliable, and Super Handy! - I’ve been using the SwitchBot Contact Sensor for a few weeks now, and I’m honestly impressed by how easy it was to set up and how well it works. I paired it with my SwitchBot Hub and it immediately started delivering real-time notifications whenever a door or window is opened. Setup took less than 5 minutes—just peel, stick, and pair. One thing I really like is the motion detection feature built into the sensor. It goes beyond just tracking open/close status and helps monitor movement in the area, making it doubly useful. Battery life looks great so far, and I love that I can check everything from my phone whether I’m home or away. If you’re looking to add an affordable and effective security boost to your smart home, this sensor is a no-brainer. It’s compact, accurate, and integrates smoothly with other SwitchBot gear. Highly recommend!

## Features

- [Window & Door Alarm Sensor for Home Security] SwitchBot Contact Sensor can detect the opening/closing of doors and windows, guarding security of the elderly, children, and pets. With the built-in light sensor, it will automatically trigger the Switchbot Bot to turn on the light when someone moves when the environment goes dark. The magnets need to be aligned with the bottom of the body, and the distance between the two components needs to be less than 1.2 inches (30mm).
- [Detects People Leaving or Entering the Home] With the built-in motion sensor, Contact Sensor will know whether you are leaving or coming home, making it possible to trigger the different actions you set in the "Scene" in the SwitchBot app. When it detects you leaving home, the appliances will automatically turn off, and when it detects you coming home, the appliances will automatically turn on. (SwitchBot Hub Mini required)
- [Easy to Install & Place It Anywhere] Thanks to the small and wireless design with long battery life, you can install Contact Sensor tool-free and get it set up in seconds. Place it on a medicine box to track whether the elderly are taking their medication, or place it on your pet's cage to know if your kitten has slipped away.
- [Part of the SwitchBot Ecosystem] Connect Contact Sensor with other SwitchBot products and set up a ”Scene“ in the SwitchBot app. When windows are opened, the SwitchBot Bot will be triggered to turn off the Air purifier automatically. (SwitchBot Hub required)
- [Remote Alert Notification & Voice Alarm from Alexa] You will receive a door-open alert notification on your phone if a suspicious person enters the house while you are away (SwitchBot Hub required). Alexa will start a voice alarm to scare off any burglars, ensuring your apartment security.

### ⭐⭐⭐⭐ Great - But Ocassionally Delayed Notifications
*by H***R on July 25, 2023*

I have this sensor mounted on an exterior door. Usually when the door is opened, I get a notification on my Android phone (Pixel 7) almost immediately (95% of the time). However there are times where notifications can take up to 10 minutes, and I'm not exactly sure why. This could be an issue with my phone and completely unrelated to this device - not sure. Othewise, as with other Switchbot products, it was easy to setup and install. Overall I'm pleased and would buy it again.
