The larger piece holds the electronics and goes on the frame. The smaller piece goes on the door or window itself. It connects over WiFi to the Tuya Smart or Smart Life app, with no separate hub listed. Easy Life Markets sells it in white as a single sensor, a pack of two or a pack of three.\u003c\/p\u003e\n\n\u003cp\u003ePeople use sensors like this to know when the front door opens while they are out, to check that a back door or garage was shut, to keep track of a medicine cupboard or a child's bedroom door, and to trigger other smart devices, such as a light that comes on when a door opens.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Is in the Box\u003c\/h2\u003e\n\u003cp\u003eThe supplier does not publish a written packing list. Each sensor is the two pieces shown in the photos, the main body and the smaller magnet piece.

With the door shut, the magnet sits beside the switch. When the door opens, the magnet moves away, the switch changes state, and the sensor reports it over WiFi. The app then records the time and sends a notification.\u003c\/p\u003e\n\u003cp\u003eBattery WiFi sensors usually sleep between events to save power and wake only when the door moves. In practice this means a notification can take a few seconds to arrive.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the Voice Assistant Support Means\u003c\/h2\u003e\n\u003cp\u003eThe supplier lists Alexa, Google Assistant and IFTTT. With a sensor, this is mainly about routines: asking whether a door is open, or having another device react when it opens. What is possible depends on each platform and changes over time, so we do not promise a particular routine. Set up the sensor in the Tuya Smart or Smart Life app first, then link that account to the assistant.\u003c\/p\u003e\n\n\u003ch2\u003eFitting It\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eAdd the sensor to the app before you stick it down, while you are standing near the router. Follow the app's steps to put it in pairing mode.\u003c\/li\u003e\n\u003cli\u003eDecide where it goes. The usual place is the top corner of the door on the opening side, with the main body on the frame and the small piece on the door.\u003c\/li\u003e\n\u003cli\u003eHold both pieces in place and open and close the door. Check that the app changes between open and closed every time.\u003c\/li\u003e\n\u003cli\u003eClean both surfaces with a dry cloth so the adhesive grips.\u003c\/li\u003e\n\u003cli\u003eFix the pieces level with each other and close together.\u003c\/li\u003e\n\u003cli\u003eName the sensor in the app after its door, and switch on notifications.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch2\u003eGetting Reliable Alerts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCheck the WiFi signal at the door. A weak signal is the usual reason for late or missing alerts.\u003c\/li\u003e\n\u003cli\u003eOn a metal door or frame, test before fixing. Steel can affect the magnet's range.\u003c\/li\u003e\n\u003cli\u003eAllow the app to send notifications and to run in the background in your phone's settings.\u003c\/li\u003e\n\u003cli\u003eReplace the batteries when the app shows them low. A sensor with a flat battery reports nothing.\u003c\/li\u003e\n\u003cli\u003eKeep the two pieces aligned.
