Trigger flood DS18B20 Temp sensor on raspberry pi

Device & model : * Hardware: Raspberry Pi 2 Model B (Sony, UK)
Sensor: DS18B20
dashboard : Web/Windows.chrome

I have connected my pi via the website and my sensors are working perfectly. The only thing that is annoying is the fact that when you put a trigger (for example temp below x), the trigger keeps generating events.
Of course, it makes sense that the condition remains true but there should be a way to stop the notifications after x triggers or so. Just for the sake of not spamming mailboxes.
I found some topics in the forum, but the only solution I could find was about changing code. Since I did all my setup without my own code I don’t see a solution.
Is there a solution or workaround?

you will need to use the python code to connect the raspberry and DS18B20 to cayenne. Sending MQTT messages within notification limit
