Nonetheless, like most clothes washers, mine has an extra rinse cycle which the buzzer sounds between cycles.
I have a Brultech energy monitor which has multiple CT clamps. Since most, if not all, high energy loads have dedicated breakers, one could simply monitor the load and send a notification/alert if something is out of the ordinary. I currently don't do this with my Brultech.
There is a point of diminishing returns (time and expense) in home automation. The more monitoring/automation devices one adds to their home, the more parasitic loads are using electricity. I justify what I already have implemented as security and convience. My neighbors have mentioned they never know when I am on business or vacation travel, my security system automatically arm/disarms and operates my garage door when a leave/arrive home, remote access to let contractors in to perform service while at work, which I can keep an eye on them with cameras.
