Sure, and if I'm off by a few minutes, that's totally fine. I honestly don't need to know the moment my clothes are done, it can wait 20-30 minutes usually. In general, a laundry run takes an hour, plus whatever soak time I choose.

So I really don't need any network access. I guess it's fine if others want it, but I see it as a liability. If it connects to a network, that's a security vulnerability (don't want a laundry DOS) and another thing to break. Ideally, every model could optionally ship without it.

Hahaha, but why?

I've used the shortest cycle, on cold, for 30+ years, with less than half the detergent "recommended". Clothes are always clean.

And my clothes get dirty. Mechanic dirty (oils are tough). Welding. Tree sap from cutting down/splitting.

Is this washing machine yours? Or is it owned by the landlord? If it's the landlord's, that's a different problem entirely, since now you need multiple people to have separate configurations on the same device to get notifications, but only when their particular load is finished.

I can absolutely see a reason to have "smart" laundromats for things like error codes, abandoned loads, usage statistics, maintenance history, full coin reservoir, etc. That's the type of problem a shared laundry room would have as well, and it would be fairly easy to add a "tap to notify" feature where you scan a QR code or tap with NFC to get remote access to it.

But for a typical home situation where the laundry machine is the apartment or house, I really don't see a point, and it's just a liability.
