Device Object

The Device object (Technically com.hubitat.app.DeviceWrapper, com.hubitat.app.ChildDeviceWrapper and com.hubitat.app.ParentDeviceWrapper) is composed of methods that allow you to interact with the settings and values of a device. This object is available to Apps that have been given access via a device selection input, as child devices of Apps and other devices and a driver also has access to this via the device object.

Returns

The current value of an attribute.
