A generic TCP/UDP network binding for openHAB that provides bidirectional text-based communication with any TCP or UDP device.

Designed as a modern replacement for the deprecated openHAB 2 TCP/UDP binding, it supports per-packet UDP mode, IP source filtering, compound command sequences, and auto-reconnecting TCP clients.

Supported Things

  • UDP Connection (tcpudp:udp): For connectionless communication. Supports per-packet or delimiter-based framing and source IP filtering.
  • TCP Client Connection (tcpudp:tcp): For persistent stream-based communication. Supports auto-reconnect and configurable timeouts.

Features

  • Compound Commands: Comma-separated command strings (e.g. KEY1,KEY2,ENTER) are automatically split and sent with 500ms spacing.
  • Source Filtering: Restrict UDP receive to specific IP addresses.
  • Per-packet mode: Each UDP datagram = one message (no delimiter needed).
  • Status Monitoring: Includes connected and lastActivity channels.

Configuration

Please refer to the README for detailed parameters for both TCP and UDP Thing types.
