@KirAsh4 I agree with OP that this is an unnatural way of counting days for humans.

Wouldn’t it be possible to do different calculations based on if it’s more or less that 24 hours?

Nice!

You say that the motion sensor is very sensitive. Do you get any false positives or is it sometimes it doesn’t trigger when it should?

I like the idea of an USB extension! Why didn’t I think of that… 😉

I suspect many have smart mirrors because of the gadget factor. Me included.

But after the first fascination was gone, our family have ended up with some really useful modules that actually is useful in our daily life:

• Calendar with everyone’s calendar, including shared family calendar, helps us plan activities and be aware of the other’s plans.
• My own MMM-Ruter module to see when next bus arrives.
• My own MMM-ThingSpeak (IoT) module (not released yet!) to see real temperature outside (the weather module is too inaccurate in our location) in addition to the weather forecast to know how to dress the kids.
• My own MMM-MotionEye module to see who’s outside my door before I open.
• MMM-doomsDay for counting down to my oldest son’s birthday or other things he is looking forward to. Before he kept asking “how many days until x?” and I had to count days or use a web service

Here is a screenshot from my mirror earlier tonight (Monday at 21:47) that shows two activities in 2 and 3 days:

They are both in the same Exchange calendar and on the same day (Thursday) as you can see here:

If this isn’t a bug, then I don’t know.

Yes, I know that the culprit is probably Moments.js, but …

Btw, the “correct” answere, in my eyes, is three days, not two.
