OWNd (Fork)

This package is an event listener and command forwarder for the OpenWebNet protocol, tailored for Home Assistant integration.

Note on this Fork: This is a modified fork of the original OWNd library by anotherjulien (v0.7.48). It includes critical hardening for connection stability, keepalive fixes for MH201 gateways, and updates to comply with modern Home Assistant development standards.

Key Enhancements in this Fork

• Connection Hardening: Reconnection mechanism now handles all connectivity drops (EOF, TCP resets/RST, aborted connections). Modernized connect() with strict timeouts to prevent hangs on unreachable hosts.
• Robust Command Delivery: OWNCommandSession.send rewritten as an iterative loop (3 retries max) instead of recursion, preventing stack overflows on unstable lines.
• HA Modernization & Security: Upgraded to target Python 3.14+, replaced pytz with native zoneinfo, and migrated xml.dom.minidom to defusedxml to address potential security vectors (Bandit/Ruff clean).
• Injectable Sessions: aiohttp sessions can now be injected directly from Home Assistant's config_flow.

Testing OWNd

Clone this repository and then execute:

cd OWNd
pip3 install .
python3 -m OWNd --help

Auto-Discovery Connection

To automatically discover the first available OpenWebNet gateway via SSDP on your local network:

python3 -m OWNd

Manual Connection

To skip discovery and force connection to a specific gateway:

python3 -m OWNd --address <IP_ADDRESS> --port <PORT> --password <PASSWORD> --mac <MAC_ADDRESS>

Note: Gateway configuration parameters can be retrieved using the BTicino Home+Project application.
