The smart meter is the benext p1 meter. No idea if this is already updated to 3.0

i found this:  
Smart meters

If you are the developer of an app that adds support for smart meters (e.g. a P1 meter for The Netherlands), you should make sure that you set the _cumulative_ flag in the device’s _energy_ object.

Also make sure that you are not providing negative _measure\_power_ values to the _setCapabilityValue_ method.

so i think its not updated yet?
