Library Design & Modules

This page aims to provide some details on the design and internals of this library. You might be interested in this if you want to improve this library, or if you are just looking to access some information that is not currently exposed.

Update Cycle

When update() is called, the library constructs a query to send to the device based on supported modules. Internally, each module defines query() to describe what they want query during the update.

The returned data is cached internally to avoid I/O on property accesses. All properties defined both in the device class and in the module classes follow this principle.

While the properties are designed to provide a nice API to use for common use cases, you may sometimes want to access the raw, cached data as returned by the device. This can be done using the internal_state property.

Modules

The functionality provided by all SmartDevice instances is (mostly) done inside separate modules. While the individual device-type specific classes provide an easy access for the most import features, you can also access individual modules through kasa.SmartDevice.modules. You can get the list of supported modules for a given device instance using supported_modules.

Note

If you only need some module-specific information, you can call the wanted method on the module to avoid using update().
