+
+The **Bitvis Power Hub** {% term integration %} reads real-time electricity data from a [Bitvis Power Hub](https://bitvis.se/) device. The Power Hub connects to the <abbr title="Home Area Network">HAN</abbr> port (a standard port on European smart meters) on your smart electricity meter and pushes measurements to Home Assistant over your local network using UDP.
+
+Because data is pushed directly from the device, no cloud connection or polling is required.
+
+## Prerequisites
+
+Before adding the integration, make sure:
+
+- Your Bitvis Power Hub is connected to your local network and configured to send data to the IP address of your Home Assistant host on the UDP port above (default: `58220`).
+- Your router or firewall allows UDP traffic from the Power Hub to Home Assistant on that port.
+
+{% note %}
+The Bitvis Power Hub and Home Assistant must be on the same network subnet, or your router/firewall must be configured to forward UDP traffic between them.
+{% endnote %}
