> It has a powerful function: if the status on the display is blank, the house is in a “healthy” state and does not need any attention. This approach of only showing what information is relevant in a given moment flies right in the face of how most smart homes approach communicating their status

Depends - my family almost always has events coming up for something, so there is always something that needs attention in the next couple days. The display has no idea when I look at it if I'm asking "is there anything tonight" - that is things where the answer is sometimes no; or if I'm asking what is planned for the rest of the week.
Likewise there are always chores. Cleaning the litter box is daily, but in the rare case where everything that must be done is done there are things like washing windows that can wait a few months but if I have time...
It is also useful to put a clock on this display - computers are accurate unlike the battery powered things you have on the wall. (though it is a matter of taste if this is worth it...)
And at least where I live I always need to know the weather for the day (if storms are expected it might be deadly to ride my bike to work even though it is fine now).
Sure knowing the temperature and relative humidity in the house isn't really useful if the system is working correct. Though it does settle some arguments so it is worth having anyway.
