Solution:
Mi Temperature and Humidity Monitor 2 supports clear data, the method of data removal is as follows: when the product works normally, open the back cover and connect the two round metal reset points above the battery with conductive materials for 5-8 seconds. After the product restarts, the setting can be restored and clear the previously stored data.
Note：
1. The two contacts are Gnd and Reset, which must be pressed at the same time. Pressing one of the contacts alone cannot restore the factory.
2. Gnd is the electrical label, and Reset is the Reset label.
3. Only the data on the product storage body will be cleared, and the data that has been synchronized to Mi Home APP will not be cleared.
