Recieve text when laptop powered on

Is there a way to get a text message sent when my kids laptop is turned on. Could this be done if laptop plugged into smart outlet.

The short answer to your question is no. Even if you were to use a energy monitoring outlet, there might not be enough difference in current flow between charging and lite operation.

I think you’ll be better served by using an app to do this; may already be one out there.

Have a script run at startup that triggers an endpoint? Just an idea
