I am still completely mystified by why it's useful to be able to check your dishwasher salt or rinse aid on a phone. When it's empty, you still have to actually fill it, so if the LED comes on just fill the tank at some point in the next 10 or so cycles and it'll do. And when old bag or bottle is empty, buy salt on one of the next 10 or so supermarket trips. The dishwasher will not need more any time soon after a refill. Maybe I'm missing a crucial piece of modern life, but it feels like yet more stats porn to go with all the metrics vomited into life by fitness trackers and apparently every piece of software.
