Troubleshooting
1. Q: If the Xiaomi Smart Temperature and Humidity Monitor 3 Mini shows incorrect values, how to solve it?
A: To solve the problem, please refer to the following steps:
1. The ventilation holes are blocked. Remove any obstructions;
2. Water gets into the ventilation holes. Dry the monitor in a well-ventilated area or use absorbent paper to wipe it dry.

A: Only when the phone is directly connected to the monitor, the temperature and humidity values displayed on the Xiaomi Home/Mi Home APP home interface will be consistent with the monitor. If the phone is only connected to the Bluetooth gateway, the value displayed on the Xiaomi Home/Mi Home APP home interface is reported by the Bluetooth gateway and will not be real-time data. The Bluetooth gateway data is updated every 5 to 10 minutes on average, and is inconsistent with the temperature and humidity data of the device because they are not updated at the same time.
4. Q: Why are the temperature and humidity data of multiple monitors inconsistent during use?
A: 1. In an open environment, temperature and humidity measurements are affected by the external environment. It is recommended that you check whether the vents are blocked. Please remove the obstructions. If water enters the vents, place them in a dry and ventilated place to dry or wipe them with absorbent paper. People approaching, walking, breathing or holding them will cause differences in the measurement results. Even the temperature and humidity at different locations in the same room can vary greatly. The temperature and humidity differences at different locations are normal;
2. It is recommended to place multiple devices in a closed environment and let them stand for about half an hour before comparing them. Although the data obtained in this way can only be used as a reference, it can reduce the impact of external environmental changes. If accurate measurements are required, they must be sent to an authoritative laboratory for testing and confirmation;
3. The humidity error standard of this product is ±5%RH (within the range of 10~90%RH), and the temperature error standard is ±0.5℃;
4. In an open environment, due to uneven distribution of temperature and humidity, even if the difference in humidity readings of two products reaches about 10%RH, it is normal. For example, one product can be within the upper limit of the error +5%RH, and another product can be within the lower limit of the error -5%RH. The difference between the two will reach 10%, but as long as they are within the error range of ±5%RH, each is in compliance with the standard;
5. Wrong comparison method: The monitor uses high-precision sensors. It is recommended not to compare the displayed temperature and humidity with the temperature/humidity of the weather forecast, humidifier, air conditioner, and the monitors of different brands.
