I have Xiaomi YI (YHS-113) camera at home and once I was wondering what servers does it connects to and what information it transmits. I had caught camera traffic on my router while it was booting and working.
Analysis revealed the following:
- Camera tried to connect to more than 20 servers.
- A part of connection is TCP, and other part is UDP.
- Not all connections were established (a part of servers didn't answer).
- Most of servers are in China, but several servers are in Amazon Cloud.
- Camera transfers to the "log.xiaoyi.com" server information about settings and WiFi name & ssid (see below).
- Camera checks is your router is Xiaomi Router or not.
- Connection to the "api.xiaoyi.com" server is secured by HTTPS with TLS 1.2.
