+
+The **Tilt Pi** {% term integration %} allows you to connect a Tilt Pi to Home Assistant to
+automatically discover Tilt Hydrometer devices.
+
+The Tilt Pi is a Raspberry Pi-based device that can read data from Tilt
+Hydrometers and broadcast it over the network. The Tilt Pi can be used to
+monitor the fermentation of beer, wine, cider, and other beverages.
+
+The benefit of the Tilt Pi is that it can be placed in a location with better
+reception than the Tilt Hydrometer itself, allowing for more reliable data
+collection.
+
+{% note %}
+For instances where you only have a Tilt Hydrometer and not a Tilt Pi, consider
+using the [Tilt Hydrometer integration](/integrations/tilt_ble).
+{% endnote %}
+
+## Prerequisites
+
+1. Have a Raspberry Pi with the Tilt Pi software installed.
+2. Have a Tilt Hydrometer in range of the Tilt Pi.
+3. Have the IP address or hostname of the Tilt Pi.

+{% configuration_basic %}
+Host:
+    description: "The hostname or IP address of the Tilt Pi."
+Port:
+    description: "The port of the Tilt Pi. The default port is 1880."
+{% endconfiguration_basic %}
+
+## Supported functionality
+
+### Entities
+
+After adding the integration, you can add the Tilt Pi device to your Home
+Assistant. If the Tilt Pi was found and there are Tilt Hydrometers in its range,
+then entities will be created for each Tilt Hydrometer.
+
+You may then use these entities in automations, scripts, dashboards, and other
+integrations.
+
+#### Sensors
+
+- **Tilt Hydrometer temperature**
+  - **Description**: Current temperature of the Tilt Hydrometer.
+  - **Entity name**: `tilt_<tilt-pi-color>_temperature`
+
+- **Tilt Hydrometer gravity**
+  - **Description**: Current specific gravity of the Tilt Hydrometer.
+  - **Entity name**: `tilt_<tilt-pi-color>_gravity`
+
+## Data updates
+
+The Tilt Pi integration {% term polling polls %} the Tilt Pi for data every 60 seconds. This
+interval is currently not configurable.
+
+## Supported devices
+
+The following devices are known to be supported by the integration:
+
+- [Tilt™ Pi v2 Bookworm May24](https://tilthydrometer.com/collections/tilt-pi/products/tilt-pi-v2-bookworm-may24-raspberry-pi-sd-card-image-download)
+
+## Removing the integration
+
+This integration follows standard integration removal. No extra steps are
+required.
