The Xiaomi Smart Temperature and Humidity Monitor 3 is a versatile assistant that helps you maintain a healthy and comfortable indoor environment. Going far beyond simple temperature readings, it consolidates six essential pieces of information onto one large, easy-to-read screen: temperature, humidity, time, date, day of the week, and an intuitive comfort level indicator.
Designed for precision, the monitor is equipped with an industrial-grade Swiss high-precision digital sensor. It can accurately detect subtle temperature changes and humidity fluctuations, refreshing every few seconds to provide real-time updates. For a quick visual check, cute facial expressions change based on the room's comfort level—a smiling face indicates a healthy environment, while a frowning face lets you know adjustments are needed.
The device features a large LCD display with a high screen-to-body ratio for enhanced readability. By default, the main display shows the temperature, but a simple press of the button on the upper right side cycles through three display modes: temperature, humidity, or time, allowing you to customize it to your preference. Additional buttons allow you to manually set the time and date or perform a factory reset.
Power efficiency is a key feature. The monitor runs on a single battery and, thanks to its ultra-low power consumption design, can provide a standby time of well over a year when not connected to the app. The thoughtful design includes round vent holes for quicker, more accurate sensing, and a durable, odorless construction. For placement, it comes with both a tabletop stand and double-sided wall adhesive, making it suitable for any room, from the bedroom and living room to the study or bathroom.
Smart Home Integration & Automation
The monitor's full potential is unlocked when connected to the Xiaomi Home app via a Bluetooth Mesh gateway. Once connected, you can trigger smart automations—set up preset conditions to automatically turn on an electric heater when the temperature drops or activate a humidifier when humidity falls below your desired level. The device can store several months of data locally, and with cloud synchronization, you can access an extended history of temperature and humidity graphs to track changes over time.
