What does a Xiaomi Mi Home device send?

Xiaomi miIO devices (plugs, purifiers, vacuums):

• Encrypted UDP to ot.io.mi.com on port 8053.
• HTTPS to xiaomi.com, mi.com, xiaomi.net.
• NTP (123).
• Local UDP port 54321 for the miIO LAN protocol.

iotaudit has a profile for this and highlights anything beyond it. Local only, no telemetry.

Check your own devices

Install and run a passive audit on your own network:
