+Ubiquiti's [UISP](https://techspecs.ui.com/uisp/wireless) (Ubiquity Internet Service Provider) product line includes various devices designed for interconnecting locations. This integration provides monitoring capabilities for devices running the airOS opearting system.
+
+There is currently support for the following device types within Home Assistant:
+
+- [Sensor](#sensor)
+
+{% note %}
+Ubiquiti UISP products cannot be managed from their popular [UniFi](/integrations/unifi/) software. They are typically configured using a web browser, the UISP Mobile App, or the UISP Cloud/Self-Hosted platform.
+{% endnote %}
+
+## Prerequisites
+
+This integration only supports devices running airOS 8 and already configured using your browser or the UISP app.
+
+{% include integrations/config_flow.md %}
+
+## Supported devices
+
+### airOS 8
+
+While there is no known limitation to which devices running airOS 8 are supported, success has been reported on:
+
+- PowerBeam 5AC gen2
+- Nanostation 5AC (LOCO5AC) 
+
+## Sensor
+
+This integration exposes the following sensor entities for your airOS devices:
+
+### Network Role
+
+Indicates the role of the device in your network, either 'bridge' or 'router'.
+
+### Wireless Frequency
+
+The base frequency set for this device.
+
+### Wireless Mode
+
+ndicates the device's role in the wireless link, typically 'ap-ptp' (Access Point Point-to-Point) or 'sta-ptp' (Station Point-to-Point).
+
+### Wireless SSID
+
+The SSID (wireless network name) used by this device.
+
+### Download capacity & Upload capacity
+
+Indicates the estimated maximum link capacity (bandwidth) for download and upload between devices.
+
+### Throughput receive and throughput transmit.
+
+These sensors show the actual data transfer rate (receive and transmit) for this device.
+
+### Antenna gain
+
+Performance in decibels of the devices antenna. See [Gain](https://en.wikipedia.org/wiki/Gain_(antenna)) on Wikipedia.
+
+## Data updates
+
+Data is polled from devices every 60 seconds.
+
+## Troubleshooting
+
+### Accessing the local device
+
+If you need to configure the device directly, you can find the link to your device by:
+
+1. Go to {% my integrations title="**Settings** > **Devices & services**" %}, and select your integration and device.
+2. On the device entry, select the link provided for the configuration URL (usually found next to the {% icon "mdi:dots-vertical" %} icon).
+3. Follow the instructions on your device's web interface or consult the [airOS 8 Manual (PDF)](https://dl.ubnt.com/guides/airOS/airOS_UG_V80.pdf).
+
+### Adjusting the update interval
+
+Please note that the [default intervals](#data-updates) are considered best practice. Updating too frequently may induce considerable load on your bridge(s) resulting in unexpected results or missing data.
