If you are thinking of data - you have to think of meta data. Instead of how often you do laundry think more:

* number of adults in the house hold (people who have access to the account)

* when you are home

* opening fridge/doing laundry/etc. I have no idea if their app has an excuse to ask for location- but app location tracking would be the most valuable data

* even if you don’t share location- these things are on your network and any regular and simple network scanning would show when certain devices are home and we they are not home and what schedules they follow

This isn’t even very imaginative, just the basics really. I would not be surprised if you could guess the household size solely based on the number of times a fridge is opened in a day. You could at least determine between a person without a family vs. family- that’s useful for ads. Are these the fridges that have cameras in them ‘so you can see what you have while at the grocery store’? Throw some image detection in there and you now know brand targeting and if they cook regularly or eat out. A goldmine of data really.
