About this item
- Make sure this fits by entering your model number.
- Hub Required: Treatlife Hub is required. Without Treatlife Hub, this zigbee door sensor does not work. Please search B09V78N28M for the Hub. To create more linkage scenes, please browse our Treatlife official store, only one gateway can realize the linkage between door contact sensor and smart devices such as switches, plugs or light bulbs, which can add infinite fun and technology to your smart life.
- Automate Your Home: Trigger Treatlife smart devices or scenes, including Treatlife smart LEDs through the open&close status in the app, e.g., have your entryway lights on automatically when you open the front door. Work with the Treatlife app and support 3rd-party integration with Alexa and Google home, set an Alexa routine to say "welcome you home." All "open" and "close" history will be saved on the APP.
- Multiple Scenarios: This door sensor alarm is an excellent security addition to any contact structure: garage doors, skylights, safes, etc. Watch the security barrier at the top of the stairs or in your child's room. Receive instant alerts if your medicine cabinet, freezer door or kitchen drawers are opened unexpectedly.
- Easy to Install: Installation is a breeze. Under the 2.4G network( NOT 5G), simply connected your smart door sensor to Treatlife app. Built-in battery can be used for 2 years or more. There is adhesive on the back on the sensor and magnet, make sure the surface is clean and dry, fitting it on any door or window. Offset as much at 5mm and gap of close to 1cm still works fine. Sensor detection is nearly instant!
- Smart Home Security Sensor: You will receive timely alert notifications from the smartphone app when the status of the protected device changes. For example, get real-time alerts at the exact moment you have an unexpected guest, a runaway child, an opened safe or an escaped pet. The Treatlife window door sensor gives peace of mind, anywhere, anytime.

Protect your privacyThe door sensor gives peace of mind anywhere anytime. Get real time alerts at the exact moment when your drawer, safes or any storage boxes for important items opened unexpectedly |

Elderly CareIf you have elderly parents at home while you are at work, monitoring the exterior doors can give you a sense of safety. Monitoring interior doors, such as bathroom and pantry can provide you with activity awareness |

Why do I need this?
We know how important the entry and exit points of your home are. These are the weakest points which the burglars can use as a welcome sign. A door sensor does what you might expect — it lets you know when a door opens. This can be a good way to monitor other people going in or out of the house, and can also be an excellent way to alert you if someone enters who shouldn’t be there.

We are impressed with the range, solid connectivity, status feedback and easy to use free app for iPhone and Android. I initially used the Treatlife app, but had no problem subsequently transitioning to the Smart Life app for my convenience since I did have some legacy devices already on my Smart Life app.
I’m in the process of adding more Treatlife devices with great expectations of success.
The motion sensor was easy to connect and set up. I was able to easily create routines for motion detection in the Amazon app.
You can also set up automations easily in the Treatlife app. I look forward to using it with other Treatlife devices.

This motion sensor is no exception. Great product. Would definitely recommend it to anyone needing to set up automation with motion.
