Port 3865xPL Home Automation Protocol

xPL carries home-automation commands and status messages, typically as unencrypted UDP broadcasts on a local network.

Technical Details

what runs on :3865

xPL messages are readable text with a message type (such as command, status, or trigger), source and target fields, a schema, and a body. Implementations typically exchange them over UDP on port 3865, often using local-network broadcasts; hubs can relay messages between devices. IANA lists both TCP and UDP, but UDP is the usual deployment, so an open TCP port should not automatically be assumed to speak xPL.

security overview

Normal xPL traffic is not encrypted and does not provide protocol-level authentication, so devices on the same network may be able to observe, forge, or send automation messages. Keep it on a trusted, segmented LAN and do not expose a listener to the public internet; the impact of accepted commands depends on the connected devices and their xPL applications.
