Maybe you can elaborate on which other features you'd find useful from that list and especially why. I really don't see it and find most of these obnoxiously unuseful.
To your given example: Not having to fill it with detergent every single time, sure I can see how that might be nice. Buy your detergent, dump a few liters in there and only do that again once some LED blinks that says "Add detergent" or something. How does a large house come into play?
Now when would a washer figure out that it needs more detergent? Probably in one of three cases: At the beginning of a wash cycle it might calculate that it doesn't have enough for this time. Don't start, blink LED that says "Add detergent". Or it figures out that it won't have enough after this cycle is done. Well, who cares, wait until I try to use the machine next time.
Or maybe it finds out in the middle of the cycle, when it no longer needs to feed any detergent but determined it's now "out". But it's still running (you know, rinsing, spinning etc). If an ADHD person gets a notification that the detergent level is low in the middle of the cycle while they're in the middle of a meeting or maybe finally got into some flow state and PING detergent is low: Why is that good? I'd rather just refill it when I'm out of any other context anyway and I'm trying to fill the machine and it won't start until I fill it up again. You know, like I also just filled it with clothes?
To have a detergent dispenser and LED light for that, the machine needs to have some brains in it. App or no app. I specifically said dispenser is the feature that I like, not its app integration.
ADHD comment was about cycle being done, not detergent. My washing machine is in the garage and there is no way for me to hear when it's done. Given that I do have ADHD, I will simply forget that I'm doing any laundry. Yeah, I can set a timer on my phone, which is what I do, but notification is more convenient.
As the original poster, I can say that it's my ADHD that made me go for a smarter machine. The amount of times I'd come back to my washing machine days later, after forgetting I'd put a wash on, was just ridiculous.
And, the fact it just works out all the settings before I get bored is good (previously I just used the same wash settings for everything, which meant creased clothes constantly - and not one pure woolen item survived its first wash!)
