The Ecolink has two primary components: the sensor and a magnet. The sensor piece mounts onto the window or door frame, and the magnet attaches to the window or door itself.

Smart Way to Go Samsung SmartThings Multipurpose Sensor
Samsung's SmartThings division offers tons of great smart home and smart home monitoring products, but in our minds, one of the most versatile is its Multipurpose Sensor. You can put it on doors, windows, or cabinets to monitor if they've been opened or closed, but you can also place it on other devices to measure tilt or vibration. You can also just use it as an ambient temperature sensor to trigger automations from your SmartThings app, Alexa app, or even IFTTT.
These are also some of the more affordable sensors available, but there is a tiny asterisk to that statement. You see, like all SmartThings products, you'll need a SmartThings Hub to connect them to each other, the app, and any other third-party devices like an Amazon Echo or Google Nest Hub.
The sensors take a CR-2450 battery (included) and can be mounted on just about any surface with the included pads, screws, and brackets. They also sport a one-year Samsung SmartThings limited warranty.
