@Wayne-TP I prefer CSV format, because they are really easy to work with (wide compatibility) and I think also easy to generate/export. As they are simple text based documents, they're pretty small...

I've got a feeling we'll never get a proper Windows app to monitor and control our devices, but what would REALLY help, especially in the energy usage/monitoring department, is to be able to export...

THE reason why I bought these plugs... only to find out the app does not have this function yet. Super powerful, especially for preventing overcharging devices or if a devices has gone into standby...
