This adds a test to check that all feature.set_value() calls will cause
a query, i.e., that there are no self.call()s that are not awaited, and
fixes existing code in this context.
This also fixes an issue where it was not possible to print out the
feature if the value threw an exception.
This can be used to hint how the sensor value should be rounded when
displaying it to users.
The values are adapted from the values used by homeassistant.
Moves `FeatureType` into `Feature` to make it easier to use the API.
This also enforces that no invalid types are accepted (i.e.,
`Category.Config` cannot be a `Sensor`)
If `--verbose` is used with the cli tool, some extra information is
displayed for features when in the state command.
Adds `FeatureType.Action` making it possible to expose features like
"reboot", "test alarm", "pair" etc.
The `attribute_getter` is no longer mandatory, but it will raise an
exception if not defined for other types than actions.
Trying to read returns a static string `<Action>`.
This overloads the `set_value` to call the given callable on any value.
This also fixes the `play` and `stop` coroutines of the alarm module to
await the call.
This adds a generic interface for all device classes to introspect available device features,
that is necessary to make it easier to support a wide variety of supported devices with different set of features.
This will allow constructing generic interfaces (e.g., in homeassistant) that fetch and change these features without hard-coding the API calls.
`Device.features()` now returns a mapping of `<identifier, Feature>` where the `Feature` contains all necessary information (like the name, the icon, a way to get and change the setting) to present and change the defined feature through its interface.
