Can do, can do
Go to the playground, Outputs and create an output like that, to create a windows notification, a pop up, a sound.. whatever you prefer.
I made one that spams me notifications every 15s if the pump speed goes below xxx RPM
I've used 2600 rpm for the test, but pumps usually have a base speed of 800 RPM
So you could set a warning if your pump goes below that for example.
