If I understand the use case correctly, it is a bit more complicated than @Adrian_Rockall described.  
The power of the device in idle state is about 100 W. 100 W is also less than 900 W. So there would be no difference if the device has a problem (600 - 800 W) or just went into idle state (100 W), the notification will be send in both cases, because the power is in both cases less than 900 W  
Therefore, the flow that is started after the timer expires needs to check the power again:

Flow #3 (like Adrian suggested)

When…  
– Timer is finished  
And…  
– power is \< 900 W (logic card)  
– power is \> 500 W (logic card, or an other value)  
Then…  
– Send notification
