Hi @DavidCP
Thank you for the feedback. I'm afraid this feature is not supported at the moment, the consumption data is only accessible when the plug is online.
About the second feedback you raised, it's definitely better if the name of energy consumption file has the tapo device's name added. While we don't have any specific details that I can share around if these two features can be achieved, or when it might, I'll make sure to log this feature request and pass it along to the team.
I'm moving this thread into the ‘Feature Requests' block for better visibility. It is recommended that you edit the subject of the post to be concise and clear, so that other users can know what the suggestion is just by reading the subject, and if they agree with you, they can directly vote on it. And please repost the second suggestion in a new post to gather clearer feedback.
