+
+The **Fing** {% term integration %} allows Home Assistant to retrieve detailed information about the devices on your local network. [Fing](https://www.fing.com/) helps home users and IT professionals monitor, protect, and understand their networks with intuitive tools that make connectivity management simple and effective. 
+By connecting through the [Local API](https://www.fing.com/developers/local-api/), Fing automatically builds and synchronizes an inventory of devices to detect online presence and trigger automations.
+
+## Prerequisites
+
+- Ensure that the [Local API](https://www.fing.com/developers/local-api/) is enabled on your Fing Agent ([Fing Agent](https://www.fing.com/agent/), Fingbox, or [Fing Desktop](https://www.fing.com/desktop/)).
+- You will need your Fing Agent’s IP address, port, and API key to complete the setup.
+
+{% include integrations/config_flow.md %}
+
+## Troubleshooting
+
+If you experience issues with the **Fing integration**, try the following:
+
+- Confirm that the Fing Agent is running and reachable on your network.
+- Verify that the configured IP address and port in Home Assistant match your Fing Agent’s actual settings.
+- Make sure your Local API version is **1.1.0** or newer.
+
+## Removing the integration
+
+You can remove this integration following the standard Home Assistant procedure.
+
+{% include integrations/remove_device_service.md %}
+
+Once the integration is deleted, you may also disable the Fing Local API on your network if you no longer plan to use it.
