In PRTG measure the power generated by the solar panel. The second parameter is the power consumed by the receivers. I want the power of the solar panel to subtract the power of the receiver. Where the value is approaching to zero wants to trigger an alarm.

Is it possible ?

Dear Artur

This is not possible within the same sensor. However, you can setup a sensor factory which computes the difference. The result channel can be used for notifications.

I have two values in two different devices:

He wants to subtract the value of "receiver" of the "solar".

Dear Arthur

Again, this can be done by creating a factory sensor. That sensor has to be configured manually including the channel definition, which means it takes some work to create this sensor. But it is the only way possible to do this kind of computation in PRTG.
