There are differences between the different measuring methods: the connected Weather station and the manual rain gauge.
These two types of data are collected differently, so it's not unusual to see differences between the measures of the 2 instruments.
The measurements obtained from our connected weather station offer further accuracy and precision than those obtained from a manual rain gauge. In fact, the larger the diameter of the container, the more accurate the data will be, which is why weather stations offer more accurate data than manual rain gauges.
PS: Careful not to overestimate the rainfall 😉
