Some individual monitored devices on energy dashboard show 0 consumption on year view

Hi,

not all my monitored devices show their consumption in the year view.
When I select only the month that they where added, they do show their consumption.
Seems that any device not present since the beginning do not show consumption in the year view.

I have made some screen shots. (Don’t know how to attach them here). I can send them by mail on request.

Best regards,

Marc
