My LG washer and dryer send a push notification to my phone when the load is done, or I can check on the minutes remaining from anywhere. The other stuff I don't care about, but that feature is pretty useful for me. Having an open API would be better, but I know 99% of their customers wouldn't know what to do with that.

$10 smart home vibration sensor works great for this. I have it all fancy in HomeAssistant so I can toggle if I want to be notified or not. You can also cue off the light if it has an led to indicate it's running.
