    How does your watch know when you are standing or not?
    I've had a busy day today, honestly! But apparently I have not been on my feet!

    It does NOT just know you only stood up. I have tested that. You have to actually move around some. I assume it mostly sees a slightly higher pulse rate. The accelerometer may need to see you have moved some. I usually get quick credit by walking a to the next room or around my table. I am not sure if anyone who knows for sure is sharing.

    Yet I have been on my feet for about 6 hours or more today. I have a 'Stand' reading of 0.

    Most of the answer (if not all of it) is that it counts you as standing if your arm is by your side, and not if your arm is out in front of you. If you walk while carrying things, it doesn't count as standing. If you stand at a kitchen bench while cooking or at a standing desk while working, it doesn't count as standing (unless you drop your arm to your side often enough for that to register). If you sit with your arm dangling down the side of the chair, it does count as standing.

    I believe arm position and arm movement are how it measure it, i.e., moving around while standing causes the arm to move in a way that's difficult (or unnatural) to move when sitting.

    The way it knows if you are "standing" is simply by detecting motion. The watch simply needs to move for 60s continuously and you will then be given a credit for standing. Easiest way to test this is if you have been using your computer for X amount of time (probably sitting): Without moving your arm anywhere, just roll your arm on the desk back and worth for 60s.

    For OP: Is this just a one time happening? Has it been working during other days? Does Wrist Raise work?

    Try rebooting the watch and make sure Wrist Raise works (the display turns on when you raise your wrist). If it's still not working try resetting it and to be 100% sure set it up as new device. If still not working it's most likely broken so you have to send it for repair.
