In the Netherlands when smart meters where introduced one of the requirements was that the meters should have a port with a defined standard (DSMR[0]) which could be used by the house occupant to read metrics for themselved. The standard is pretty well setup with newer versions giving per second power/gas usage readings in human parsable ascii over rs232 on an rj11 connector.
