It is possible to obtain information about available features of a device, e.g. if it supports playback actions or power management, using interface.Features. Supported features are listed in const.FeatureName.

Feature State

A feature can at any given time be considered to be in one of the following states:

State Meaning
Unknown The feature is supported by the device but it is not possible to determine if it is available or not, i.e. if it can be used now. All devices for instance supports Pause, but it is only possible to pause if something is playing.
Unsupported The feature is not supported by the device at all, e.g. Siri is unsupported on Apple TV 3 or none of the configured protocols support this feature.
Unavailable The feature is supported but currently not possible to use, e.g. skip to next track is only possible if a song is playing.
Available The feature is supported and available now, e.g. Pause is possible because something is playing.

Because of technical reasons, the state of some features are not possible to determine, so pyatv will make an educated guess. If something seems strange, please write an issue about it. Make sure you include full debug logs, otherwise it will be hard to troubleshoot.

Using the Features API

After connecting to a device, you get the interface via interface.AppleTV.features:

atv = await pyatv.connect(config, ...)
ft = atv.features

To obtain current state of a feature, e.g. const.FeatureName.Play, use interface.Features.get_feature:

from pyatv.const import FeatureName, FeatureState

info = ft.get_feature(FeatureName.Play)
if info.state == FeatureState.Available:
    print("Play is not possible right now")

The state of all features can be obtained via interface.Features.all_features. By default, this method will exclude unsupported features. Pass include_unsupported=True when calling to include state of all features:

all_features = ft.all_features(include_unsupported=unsupported)
for name, feature in all_features.items():
    print(f"{name} = {feature.state}")

There’s a helper method, interface.Features.in_state, that checks if one or more features are in one or several states:

# Check if Play is available
if ft.in_state(FeatureState.Available, FeatureName.Play):

# Check if Play is either available or unsupported
if ft.in_state([FeatureState.Available, FeatureState.Unsupported],

# Check if Play *and* Pause are supported
if not ft.in_state(FeatureName.Unsupported, FeatureName.Play, FeatureName.Pause):
