## Description

Easily monitor doors and windows with this wireless contact sensor. Automatically triggers lights when motion is detected in dark environments to enhance home security.

Review: Take your time to find the optimum postion, experiment. - These sensors are exellent, just take your time to find the optimum position for each sensor, precence works very well as does the motion, i have three set up, and these are then controled by home assistant, the one on the front door turns on a porch light when the door is open and I am entering the house after sunset, and the sensor will turn on the prch and hallway when leaving and both turn off a a predefined time after. The other two I just use as sensors one on the landing to turn on a light if I am going up or down the stairs after sunset and before sunrise. I've had them a few months now and they work floorlessly. Brilliant
Review: Easy to install, smart to use - Smart home systems can be clunky and difficult to use, but the SwitchBot ones are great. They work well straight out of the box. There is enough customisation available in the app so you can do what you want, without it being too technical and overly complicated. Would 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.
- [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. Alexa will start a voice alarm to scare off any burglars, ensuring your apartment security. [Remote Alert Notification] You will receive a notification if a suspicious person enters the house while you are away. (SwitchBot Hub required)

## Questions & Answers

**Q: Will I be able to see the status when I am away from my flat if I placed this on the front door?**
A: It shows the status of the sensor in the SwitchBot app. You can also run Alexa routines with this sensor to make a sound through an amazon speaker when opened.

**Q: Can i add few of those at the same time on the app , together ?**
A: Yes, I have 3 of them

**Q: How much wifi will it use? Im wanting to place it in my toolbox at work (no wifi) so will have to get a 4g router im just curious how much it will cos**
A: Dear customer

Thanks for asking! This item is a Bluetooth product, and it works as a trigger for your SwitchBot product line. If you would like to get longer distance interaction, it might need a SwitchBot Hub Mini (sold separately) to connect to WiFi

**Q: Can you detect motion without the door sensor being triggered? e.g. door is shut and someone walks past? will it detet that**
A: Yes. If you have the hub and if you’re triggering another SwitchBot device.

### ⭐⭐⭐⭐ Look for your hubs device limit. if using Apple Home
*by L***1 on 27 October 2025*

I recently purchased the door lock that came with the Hub Mini, along with a Switch Bot device. I was impressed with the brand and decided to purchase two external temperature sensors. 1 for my refrigerator and a second for my bathroom. I noticed these on offer, so purchased four additional sensors to add to my Apple Home via Matter. However, I discovered that there is a device limit for the Hub Mini. This means that I would need to purchase another Hub. btw. I attempted to remove the temperature sensors from the Hub Mini, as per the support document, but the Hub Mini informed me that the sensor wire must be connected. I am unsure what this means, so I am unable to add any more devices. Apparently, the device limit is eight, but I am only able to add the four, I already purchased 4 so hit my limit. The Matter support is misleading. The whole purpose of Matter is to eliminate the need for multiple hubs for different devices.so Its unfortunate, as I had the Black Vacuum Bot in my wish list waiting for updates for HomeKi and to be back in stock. I also been waiting months for the black remote to also be back in stock. but tbh I am unwilling to purchase another Hub, as I already have way too many. and one more is a deal breaker. Great brand, great products, and removed 1 star as the actual devices look and feel premium and great features that was looking forward to use. but the device limit made me return them. but if anyone had the larger hub already then these are amazing products as very good features at way less than other brands. i recommend this product even though I returned. as its my choice not to purchase another hub.
