+## Zigbee2MQTT Import
+
+Homelable can connect directly to your MQTT broker and import your Zigbee network topology from **Zigbee2MQTT**, placing each device on the canvas as a typed node.
+
+### Prerequisites
+
+- A running **MQTT broker** (e.g. Mosquitto) accessible from the Homelable host
+- **Zigbee2MQTT** connected to the broker with at least one device paired
+
+### Usage
+
+1. Click **Zigbee Import** in the left sidebar (below "Scan Network")
+2. Enter your broker host, port (default `1883`), optional credentials, and base topic (default `zigbee2mqtt`)
+3. Click **Test Connection** to verify reachability, then **Fetch Devices**
+4. Select the devices you want from the grouped list (Coordinator / Router / End Device)
+5. Click **Add N to Canvas** — devices are placed in a grid with IoT edges
+
+### Node Types
+
+| Type | Z2M Device | Icon |
+|------|-----------|------|
+| `zigbee_coordinator` | Coordinator | Network hub |
+| `zigbee_router` | Router (mains-powered) | Radio |
+| `zigbee_enddevice` | End Device (battery) | Antenna |
+
+Hierarchy is set automatically: coordinator → routers → end devices (`parent_id`).
+LQI (Link Quality Indicator) is stored as a node property.

-## MCP Server (AI Integration) (optionnal)
+## Gethomepage Widget (read-only stats)
+
+Homelable can expose a small JSON stats endpoint that [gethomepage](https://gethomepage.dev) consumes through its built-in `customapi` widget. Disabled by default.
+
+### Activation
+
+Add `HOMEPAGE_API_KEY` to your `.env`:
+
+`HOMEPAGE_API_KEY=your-secret-key`
+
+Restart the backend (`docker compose restart backend`).
+
+### Endpoint
+
+`GET /api/v1/stats/summary` — requires header `X-API-Key: your-secret-key`. Returns:
+

+  "zigbee_devices": 5,
+  "last_scan_at": "2026-05-14T10:00:00+00:00"

+```
+
+The backend port (`8000`) must be reachable from your gethomepage container.

+
+## MCP Server (AI Integration) (optional)
 
 Homelable can exposes a [Model Context Protocol](https://modelcontextprotocol.io) server so any MCP-compatible AI client (Claude Code, Claude Desktop, Open WebUI…) can read your homelab topology and act on it.

+# Zigbee2MQTT Network Map Importer
+
+This feature lets you connect Homelable to your MQTT broker, fetch the Zigbee2MQTT network topology, and drop all Zigbee devices onto the canvas as typed nodes with proper hierarchy.
+
+---
+
+## Feature Overview
+
+- **Automatic device discovery** — Requests the Z2M networkmap via the MQTT bridge API and parses the full device list
+- **Typed nodes** — Devices are mapped to three homelable node types:
+  - `zigbee_coordinator` — The Zigbee coordinator (hub)
+  - `zigbee_router` — Mains-powered router devices
+  - `zigbee_enddevice` — Battery-powered end devices (sensors, bulbs, etc.)
+- **Hierarchy** — `parent_id` is set automatically: coordinator → routers → end devices
+- **LQI display** — Link Quality Indicator is stored as a node property
+- **IoT edges** — Links between devices are added as `IoT / Zigbee` edge type
+
+---
+
+## Prerequisites
+
+1. A running **MQTT broker** (e.g. Mosquitto) accessible from your Homelable host
+2. **Zigbee2MQTT** connected to the broker and running
+3. Z2M must respond to networkmap requests on:
+   - **Request topic:** `<base_topic>/bridge/request/networkmap`
+   - **Response topic:** `<base_topic>/bridge/response/networkmap`
+   - The default base topic is `zigbee2mqtt`
+
+---
+
+## Step-by-step Usage
+
+### 1. Open the Zigbee Import dialog
+
+Click **Zigbee Import** in the left sidebar (below "Scan Network").
+
+### 2. Configure the MQTT connection
+
+| Field | Default | Description |
+|---|---|---|
+| Broker Host | — | IP or hostname of your MQTT broker |
+| Port | 1883 | MQTT broker port |
+| Base Topic | `zigbee2mqtt` | Zigbee2MQTT base topic |
+| Username | _(optional)_ | MQTT username if authentication is enabled |
+| Password | _(optional)_ | MQTT password |
+
+### 3. Test the connection (optional)
+
+Click **Test Connection** to verify broker reachability before fetching devices.  
+A green indicator confirms success; red shows the error message from the broker.
+
+### 4. Fetch devices
+
+Click **Fetch Devices**. Homelable will:
+1. Connect to the broker
+2. Subscribe to the response topic
+3. Publish `{"type": "raw", "routes": false}` to the request topic
+4. Wait up to 60 seconds for the network map response (large meshes can take 30 s+)
+5. Parse and group devices by type
+
+### 5. Select and add to canvas
+
+Devices are grouped by type (Coordinator / Router / End Device).  
+Use the checkboxes to select which devices to add, then click **Add N to Canvas**.
+
+> **Tip:** All devices are selected by default. Uncheck any you don't want.
+
+### 6. Arrange on the canvas
+
+Devices are placed in a grid at the top-right of the canvas.  
+Use **Auto Layout** (toolbar) to re-arrange the full canvas, or drag nodes manually.
+
+---
+
+## MQTT Configuration Tips
+
+### Mosquitto without authentication
+
+```
+listener 1883
+allow_anonymous true
+```
+
+### Mosquitto with password file
+
+```
+listener 1883
+password_file /etc/mosquitto/passwd
+```
+
+Create a user:
+```bash
+mosquitto_passwd -c /etc/mosquitto/passwd <username>
+```
+
+### Zigbee2MQTT `configuration.yaml`
+
+```yaml
+mqtt:
+  base_topic: zigbee2mqtt
+  server: mqtt://localhost:1883
+  # user: mqtt_user
+  # password: mqtt_password
+```
+
+---
+
+## Supported Z2M Versions
+
+The networkmap bridge API is available in **Zigbee2MQTT 1.x and 2.x**.  
+Tested against Z2M 1.35+ and 2.x.
+
+The importer uses the `raw` topology format (`routes: false`) which is the most widely supported mode.
+
+---
+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---|---|---|
+| "Connection refused" | Broker unreachable | Check host/port, firewall rules |
+| "Timed out waiting for networkmap" | Z2M not running or wrong base_topic | Verify Z2M is connected, check base_topic setting |
+| 0 devices returned | Z2M has no devices paired | Pair at least one device first |
+| "Malformed networkmap response" | Z2M returned unexpected format | Check Z2M version; open an issue |
+
