Smart Home Control Technology Analysis
Realizing device control relies on three major technology components:
- MIot protocol: Xiaomi Eco's open communication protocol, direct connection to devices via LAN/WiFi
- Voucher Binding: Need the did (device ID) and token (access token) of the device under the Mi Home account
- local relay: the client's built-in command forwarding service that converts natural language into API calls
Required before use:
- All devices need to be connected to the same local area network (2.4 GHz band)
- Enable "LAN Control" privilege in Mi Home App
- Clients need to do device discovery (broadcast udp:54321 port)
- Voice commands need to contain a clear location + device + action (e.g. "turn off the lamp in the bedroom")
