Newbie - Notification based on power consumption

Night 4 with mi casa verde setup.

Still liking the z wave functionality. The camera functionality is pretty weak though.

I have a smart switch energy meter on my dehumidifier. When the water tank is full in the thing not surprisingly it stops dehumidifying and the power consumption drops.

What I’d like to do is send a notification when the energy consumption drops so I know I need to go dump it.

Pretty new to this, but I didn’t see any way to do that. Am I missing something?
