What is Virtual sensor's measuring interval?
Posted: 06.07.2021 09:26
In case when virtual sensor input contains sensors with different measurement intervals, virtual sensor measurement interval will be the smallest interval of input sensor intervals.
F.e., Average temperature virtual sensor has input from sensor 1 with measurement interval 2 minutes, sensor 2 with measurement interval 2 minutes, sensor 3 with measurement interval 5 minutes, and sensor 4 with measurement interval 10 minutes. In this case, Virtual sensor's measurement interval is 2 minutes.
As each sensor captures measurement at different times, to calculate virtual measurement Aranet Cloud performs time synchronisation - the closest measurements in time from several sensors are searched and their values are added, averaged, or otherwise calculated. This process can lead to situations where virtual sensor measurements are displayed with a delay. The larger the measurement interval of the input sensors, the greater the delay that may occur in displaying the current measurements.
