Been away from ST for a bit. Questions regarding its state

I took this from another post, but it explains it best:

You can set the amount of time it takes for a presence tag to be marked absent.

So if you’re having problem with it checking in and out a lot for no reason you can set it to be longer to get rid of false positives. Or if you want it faster you can increase it. I think default is 2 minutes.
