I do use the timer delay to run the wash cycle when the power is cheap. I'd really like it if I could set it as "ready to go" and something else give it the "go" when the power is cheap.
Once I have that, it's also useful to have something to tell me there's wet washing that needs to be unloaded.
If my washing machine was older I could do all of this with a remote power switch and sensor, but because my washing machine has touch buttons instead of click/clacks, I can't. Turning the power on just makes it wait for a button press.
Only works if you can start a cycle on power on. My machine will just sit there waiting for someone to press the go button.
