I am using the DSC06106-ZWUS with my setup for the washing machine and using Rule Machine with a virtual switch, I can get notifications.
I have it set up so that when my washing machine goes over 4W it will turn on a virtual switch.
Then I have a rule that states if the draw falls under 4W with that virtual switch on, I will get a text message and also have a message spoken over my speaker (as well as turning off the virtual switch as a reset for the next use).
