unifi-topology 2.2.0

Python library for UniFi network topology discovery and SVG rendering

unifi-topology

Python library for UniFi network topology discovery and SVG diagram rendering.

Extracted from unifi-network-maps to provide a clean library API for programmatic use, including the Home Assistant integration.

Installation

pip install unifi-topology

Quick Start

from unifi_topology import (
    Config,
    SvgOptions,
    build_node_type_map,
    build_topology,
    extract_wan_info,
    fetch_devices,
    fetch_networks,
    normalize_devices,
    render_svg,
    resolve_svg_themes,
)

# Connect to UniFi controller
config = Config.from_env()
api_devices = fetch_devices(config)
networks = fetch_networks(config)

# Build topology model
devices = normalize_devices(api_devices)
node_types = build_node_type_map(devices)
gateways = [name for name, node_type in node_types.items() if node_type == "gateway"]
topology = build_topology(
    devices,
    include_ports=True,
    only_unifi=False,
    gateways=gateways,
)
gateway = next((device for device in devices if node_types.get(device.name) == "gateway"), None)
wan_info = extract_wan_info(gateway) if gateway else None

# Render SVG
theme = resolve_svg_themes(theme_name="unifi")
options = SvgOptions()
svg = render_svg(
    topology.tree_edges or topology.raw_edges,
    node_types=node_types,
    theme=theme,
    options=options,
    wan_info=wan_info,
)

API Overview

Adapters

• Config -- Configuration from environment variables (UNIFI_URL, UNIFI_USER/UNIFI_PASS or UNIFI_API_KEY, etc.)
• fetch_devices(config) -- Fetch device list from UniFi controller
• fetch_clients(config) -- Fetch active clients
• fetch_networks(config) -- Fetch network/VLAN configuration
• fetch_firewall_zones(config) -- Fetch firewall zone definitions
• fetch_firewall_policies(config) -- Fetch zone-based firewall policies
• fetch_firewall_groups(config) -- Fetch firewall address/port groups
• resolve_hostnames(ips, dns_server) -- Reverse DNS resolution

Model

• normalize_devices(raw) -- Convert raw API data to Device objects
• normalize_firewall_zones(raw) -- Convert raw zone data to FirewallZone objects
• normalize_firewall_policies(raw) -- Convert raw policy data to FirewallPolicy objects
• normalize_firewall_groups(raw) -- Convert raw group data to FirewallGroup objects
• build_node_type_map(devices, clients=None, ...) -- Classify node names for rendering
• build_topology(devices, *, include_ports, only_unifi, gateways) -- Build topology graph (TopologyResult with raw_edges and tree_edges)
• build_device_inventory(devices) -- Build device info table (list[DeviceInfo])
• extract_wan_info(device, ...) -- Extract WAN upstream info for a gateway device

Rendering

• render_svg(edges, *, node_types, theme, options, ...) -- Orthogonal SVG diagram
• render_svg_isometric(edges, *, node_types, theme, options, ...) -- Isometric 3D-style SVG
• render_dual(edges, *, node_types, theme, options, ...) -- Physical + VLAN grouped SVG output
• resolve_svg_themes(theme_name, theme_file) -- Load built-in or custom SVG theme

Built-in themes: unifi, unifi-dark, minimal, minimal-dark, classic, classic-dark
