SwitchBot Door Alarm Contact Sensor - Smart Home Security Wireless Window Alarm and Door Sensor, Add SwitchBot Hub Mini to be Compatible with Alexa (1 Pack)

Same quality that I've had with all my switchbot products. Very responsive - alert sent to my phone within 2 seconds. Very easy to install. Compatible with Alexa and Google Home. Connects seamlessly throigh the switchbot app. Great value for money.

Switchbot's Contact sensor is useful in many situations. It's easy to install and the Switchbot app provides settings for it to be used on a door or a cupboard. I even have one attached to a cat flap!Battery life is good and, as well as linking to the Switchbot app, I have also connected the contact sensor to the Samsung Smartthings app which allows me to control non-Switchbit bulbs via the sensor.The sensor also includes a small motion sensor which allows you to determine if visitors are leaving or arriving alongside a light sensor.I have found that notifications via the Switchbot app can be delayed (despite disabling battery optimisation etc) but they come through instantly via Smartthings.I have purchased contact sensors from other manufacturers in the past but this is the most versatile by far.

Motion sensor works well with my other switchbot products. My only gripe is that it seems to the batteries don't seem to last long and I'm constantly putting AAs in it. The app is very good and I much prefer it to the ewelink application.

Amazing it works with switch app and I can be informed on my phone when door is left opened by accident. Also I link it to other automation to trigger my lights and other things on when I get open or leave like turning off lights!

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

These Contact Alarms work brilliantly, I have mine connected up to my Homey Smart home System and they are fool proof

These are the most reliable and battery efficient door sensors I have found.They are at first glance feature packed as they have multiple sensors built in. From the obvious door open and closed detection it also has built in... Ambient light level sensing, motion sensing (which when used in conjunction with the door open and closed sensor determines if you're vhave entered of left the room/building), temperature sensing and finally a button to trigger events or scenes.So what's the problem? Surely the reliability and all these features should get them a 5 star rating? Well yes they would... BUT...Most of these features aren't presented to other devices/frameworks such as Alexa or Smartthings. This means that the only features available to trigger an event or scene is the door open or closed sensor.This means it can't be used for launching a simple scenes such as turning the lights on when entering a room (and when it's dark) and off again when leaving the room.This is a major flaw and limitation. I'm can't say if this limitation can be overcome using something like IFTTT or Home Assistant.

I've tried a lot of different contact sensors but this one is the only one with the motion sensor built in, which is brillant.Am using homebridge on RaspberryPi to make it even more integrated, now, when I go into the lobby, the motion sensor turns on my Hue lights, so I don't even need to open the door. Perfect!The only downside is I can't program the button to do anything - would have loved to be able to control this to set my Ring alarm when leaving the house, but not even the Homebridge plugin opens this up.If you have SwitchBot lights I'd imagine the button comes in very handy.Usual build quality from SwitchBot too, have loads of their products and always top notch.

Thankyou. Item as described. Easy postage.

spend hours trying to connect it to Alexa or smart life app but it fails..its only connects to smartbot app and can't access it outside this app...after alot of search i find out you need to buy another device (hub) to be able to connect to third party assistant like Alexa. Seller should mention that on description. Usless. Im returning it back

Na de automatische updates werkt de sensor perfect.

The SwitchBot Door Alarm Contact Sensor is the best of both worlds—it combines a motion sensor and a door sensor in one compact device. It's incredibly versatile and works great on windows too. Now that it's compatible with Matter, it's even better. This is hands down one of the most useful smart sensors I’ve added to my home.
