+title: Siren Entity
+sidebar_label: Siren
+---
+
+A siren entity is a device whose main purpose is to control siren devices like a doorbell or chime. Derive entity platforms from [`homeassistant.components.siren.SirenEntity`](https://github.com/home-assistant/home-assistant/blob/master/homeassistant/components/siren/__init__.py)
+
+## Properties
+
+> Properties should always only return information from memory and not do I/O (like network requests). Implement `update()` or `async_update()` to fetch data or build a mechanism to push state updates to the entity class instance.
+
+| Name                    | Type   | Default                               | Description                                                                             |
+| ----------------------- | ------ | ------------------------------------- | --------------------------------------------------------------------------------------- |
+| is_on                   | bool   | `NotImplementedError()`               | Whether the device is on or off.                                                        |
+
+### Tones
+
+A device can have different tones that are played. Integrations are responsible for providing the available tones when supported.
+
+### Supported features
+
+Supported features constants are combined using the bitwise or (`|`) operator.
+
+| Name                      | Description                                                                                                      |
+| ------------------------- | ---------------------------------------------------------------------------------------------------------------- |
+| `SUPPORT_TONES`           | The device supports different tones (the tone can be passed in to `turn_on` service).                                |
+| `SUPPORT_DURATION`        | The device supports setting a duration for the tone (the duration can be passed in to `turn_on` service).            |
+| `SUPPORT_VOLUME_SET`      | The device supports setting the volume level of the device (the volume level can be passed in to `turn_on` service). |
+
+
+## Methods
+
+### Turn on
+
+There are three optional input parameters that can be passed into the service call, each gated by a supported feature flag. If the corresponding flag isn't set when a given input parameter is provided in the service call, it will be filtered out from the service call by the base platform before being passed to the integration.
+
+| Parameter Name 	| Data Validation                       	| Supported Feature Flag 	|
+|----------------	|---------------------------------------	|------------------------	|
+| `tone`         	| `vol.Any(vol.Coerce(int), cv.string)` 	| `SUPPORT_TONES`        	|
+| `duration`     	| `cv.positive_int`                     	| `SUPPORT_DURATIONS`    	|
+| `volume_level` 	| `cv.small_float`                      	| `SUPPORT_VOLUME_SET`   	|
