+Integrates [SNOOZ](https://getsnooz.com/) devices into Home Assistant.
+
+{% include integrations/config_flow.md %}
+
+The SNOOZ integration will automatically discover devices once the [Bluetooth](/integrations/bluetooth) integration is enabled and functional.
+
+## Supported devices
+
+- [SNOOZ White Noise Machine](https://getsnooz.com/products/snooz-white-noise-machine)
+
+## Setup
+
+Once a device is discovered, it needs to be put into pairing mode to complete setup.
+
+### Entering pairing mode
+
+1. Ensure the device is not connected to a mobile app or any other Bluetooth controller.
+2. Hold your finger on the power button until all buttons begin pulsing on and off (~ 5 seconds).

+
+## Platforms
+
+### Fan
+
+Devices are exposed as Fan entities with a persistent connection to the device.
+
+Fan speed percentage is mapped to the device volume level.
+
+<div class='note'>
+Speed percentages less than 10 have no effect - they all map to a value of 1 on the device.
