Factory sensor does not use current Channel values



I have a simple factory sensor that reads two values out of another sensor/channel and adds those together. When I set the Interval larger than a few minutes. It ignores newer values from the other sensor. Even manual "Scan now" does not help. With shorter Intervall times "Scan now" does work again.

When I set the Intervall to a large time, like 60 min. The sensor even reverts to older values that are not true anymore. Short interval current values, back to long interval old values. I can do this back and forth.

Do factory sensors use cashed values?

Hi there,

Please ensure that the scanning interval of this sensor is equal to or greater than the scanning interval of the source sensors to avoid incorrect sensor behavior. For example, "no data" messages or erratic changes of the sensor status can be a result of an invalid scanning interval.

Here you'll find more information about the sensor: https://www.paessler.com/manuals/prtg/sensor_factory_sensor
