iPhone Hotspot: who is connected? Sometimes, when I start to use my iPhone as a hotspot, I see 2 connections. Since I am the only one supposed to be using it, and I’m only using wifi (not USB as well), I can’t work out why there is a second connection.

After a while, it often goes down to 1 connection. I wonder whether the second connection is someone else trying to use it.

The question is: how can I tell who is accessing the hotspot?

BTW, the initial problem was to resolve why I appear to be having more connections than I could account for, and that is indeed covered in another question. However, I would still like to know whether it’s possible to see who is actually connected.
Other devices (including iPads, iPods, Macs, and other iPhones) connected to the same iCloud account as your iPhone will, if in WiFi range, automatically connect to your iPhone's hotspot when it's turned on (according to this Apple Support page and my personal experience). That means if any of your other devices are lying around, they will automatically connect to your iPhone's hotspot using iCloud.

tl;dr: Other devices tied to the same iCloud account might automatically be joining your iPhone's hotspot network.
