UDP 9898
Synopsis
- Xiaomi/Aqara Smart Home Gateway (lumi.gateway v2/v3) uses UDP port 9898 for its local LAN protocol, broadcasting on 224.0.0.50:9898 for discovery and messaging.
- Home automation platforms and integrations such as Home Assistant’s “Xiaomi Gateway (Aqara)” integration, Domoticz’s Xiaomi plugin, openHAB’s Xiaomi Mi Smart Home binding, ioBroker’s mihome adapter, and homebridge-mi-aqara communicate with the gateway over UDP 9898.
- This port is used to discover devices and exchange status/control messages between the gateway and third‑party controllers on the local network.
- Some reports and research have noted security weaknesses in older Xiaomi/Aqara gateway firmware around the UDP 9898 LAN protocol (e.g., risks if exposed to the internet or if the LAN key is obtained), leading to occasional abuse of misconfigured devices.
