Siren Entity

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



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.

is_onboolNoneWhether the device is on or off.
available_toneslist or dictNotImplementedError()The list or dictionary of available tones on the device to pass into the turn_on service. If a dictionary is provided, when a user uses the dict value of a tone, it will get converted to the corresponding dict key before being passed on to the integration platform. Requires SUPPORT_TONES feature.


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.

SirenEntityFeature.TONESThe device supports different tones (the tone can be passed in to turn_on service).
SirenEntityFeature.DURATIONThe device supports setting a duration for the tone (the duration can be passed in to turn_on service).
SirenEntityFeature.VOLUME_SETThe device supports setting the volume level of the device (the volume level can be passed in to turn_on service).


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.
