Some modules have attributes that may not be supported by the device.
|
||
|
|
These attributes will be annotated with a `FeatureAttribute` return type.
|
||
|
|
For example:
|
||
|
|
|
||
|
|
```py
|
||
|
|
@property
|
||
|
|
def hsv(self) -> Annotated[HSV, FeatureAttribute()]:
|
||
|
|
"""Return the current HSV state of the bulb."""
|
||
|
|
```
|
||
|
|
|
||
|
|
You can test whether a `FeatureAttribute` is supported by the device with {meth}`kasa.Module.has_feature`
|
||
|
|
or {meth}`kasa.Module.get_feature` which will return `None` if not supported.
|
||
|
|
Calling these methods on attributes not annotated with a `FeatureAttribute` return type will return an error.
