## Summary description

Xiaomi Mi Smart Sensor Set ZHTZ02LM is a wireless door and window sensor kit in white designed for home security and automation.

Use the sensors to detect open/close status, integrate with smart home systems and receive alerts for doors and windows.

## Long description

The Xiaomi Mi Smart Sensor Set ZHTZ02LM is a wireless door and window sensor kit in white intended for home security and basic automation. The set detects open and closed states of doors and windows and transmits status changes over a wireless connection. It uses user-replaceable button cell batteries (CR1632, CR2032 or CR2450) and can be integrated into smart home setups to trigger notifications, scenes or linked devices when contact is made or broken.
Advantages
This sensor set provides compact magnetic detection with wireless connectivity suitable for discreet installation on frames and sashes. Battery operation with common CR1632, CR2032 or CR2450 cells allows straightforward replacement without specialist tools. The white finish is intended to blend with most interiors while the simple design supports integration into broader smart home automation for event-based actions and alerts.
Suitable for (tasks / use cases)
 Monitoring doors and windows for open/close status in apartments and houses
 Triggering smart home automations such as lighting, alarms or notifications
 Temporary or permanent installation on interior doors, windows or cabinets
When it may not be suitable
This sensor set is designed for basic contact detection and not for professional-grade security installations that require tamper-proof housings, wired power or certified intrusion detection. It relies on replaceable button cells and wireless communication, so environments that demand continuous high-frequency reporting or operate far beyond typical home wireless ranges may need alternative hardware.
Key specifications
 Function: Magnetic contact sensor (open/close detection)
 Color: White
 Power supply: Replaceable button cell batteries (CR1632, CR2032 or CR2450)
 Connectivity: Wireless
 Mounting: Surface-mounted on door or window frame and sash
How to use
Mount the sensor body on the fixed frame and the magnet on the moving part (sash or door) so that the two parts align when closed. Insert the correct type of battery according to the device’s orientation and manufacturer's instructions, observing polarity. Pair the sensor with your Xiaomi-compatible smart home hub or app via the wireless setup procedure described in the hub’s documentation. Configure notifications, automation rules or linked devices in the smart home app to act when the sensor reports open or closed states.
What to consider before purchase
 Confirm compatibility with your existing smart home hub or Xiaomi ecosystem before buying
 Decide which battery type (CR1632, CR2032 or CR2450) you will use and whether you want longer life vs. size
 Check mounting surface and alignment space to ensure proper magnet-to-sensor positioning
Usage recommendations
For reliable operation, install the sensor within the wireless range of your hub and avoid metal surfaces that can interfere with the signal. Test alignment after mounting to ensure the sensor registers closed state consistently. Replace batteries as soon as low-battery alerts appear and follow local guidelines for battery disposal.
