Personally I think notification is the potential life changer most people don’t realize. Imagine an easy way to tell when the laundry is done without that godawful buzzer. Did I leave the stove on? Is there water in the basement? Is my fridge out or otherwise not leaping cool? What about my garage door? Is the hose running?

A house that can let you know when something is wrong would be huge. Today, a few techies can make that happen with sufficient time and effort. Matter can make that straightforward for everyone. My Mom could never understand Home Assistant or all the components, but she can act when the house tells her she left the oven on
