My washer and dryer are miele, and the remote notifications are useful. I've used some of the remote start features to ensure the machines run when the solar is generating, but that's about it

Honestly I'd have been better with the speed queen and a relay wired into the starter switch.

As for the dishwasher, I rigged up my current one to send me end of cycle alerts by putting a current detector loop around it's power inlet, and alerting when it goes from high to low and stays that way for a period
