Warning that custom component is using device_state_attributes

Configuration
1

Updated to 2012.12.x and I am seeing these warnings.

Entity sensor.emoncms_use (<class 'custom_components.emoncms2.sensor.EmonCmsSensor'>) implements device_state_attributes.

As I am nominally the maintainer, I probably need to do something to the component, but I have no idea what this log message means.

Can someone point me to the relevant release note and or the documentation regarding this, or even better, tell me what needs fixing :slight_smile:

Entity looks like this;

Rename the property device_state_attributes to extra_state_attributes

Thanks - discovered I had an old ‘second’ copy in my custom components :frowning:
