Why does the Xiaomi Smart Pet Food Feeder 2 have the deviation in dispensing time

The factors affecting the dispensing time of the Xiaomi Smart Pet Food Feeder 2 dispensing food are listed below:  
1. The current feeder is in emergency functions (powered by four 5-cell alkaline batteries), under which the Wi-Fi function is disabled and only the basic function of dispensing food is retained. Therefore, the fact that automatic feeding plan experiences a  delay of several seconds is a normal occurrence;
2. If the time zone on your phone does not accord with your current location, the time node of dispensing food will be based on the original set-up. Although the food is dispensed successfully, the Mi Home/Xiaomi Home APP will display failure of dispensing or abnormal dispensing time.
