That's a feature I'd kinda like, but I won't rope myself into the manufacturer's ecosystem just to get it. Especially not Samsung, the maker of my current washing machine. Not that I'll ever buy another Samsung appliance, but that's a different story.

What I did instead was paste an Aqara zigbee vibration sensor to the side of the washing machine. Then a little bit of Home Assistant magic and it tells me when the washer seems to be done. In case I didn't hear the symphony it plays at the end of a cycle.

Is the chime at the end of the cycle inadequate?

My washer is not where I always hear it and the notification on my phone is a handy reminder.

Yes, because it assumes you can hear it.

If you're too far away to be able to hear it, then what would you do with the information anyway?

Kids, life, family, noise happens, it is pretty easy to have it go off and not hear it, but still want to get to it when it is done.
