For people in The Netherlands: all Smart Meters that the net maintainers installed (are required to) support the P1 standard, which provides a standardized interface for customers to read out current current draw, cumulative power use, etc. Usually gas is hooked as well. You can hook up a cheap dongle to expose the stats in an app. For instance, we use: https://www.homewizard.com/nl/shop/wi-fi-p1-meter/ https://www.homewizard.com/nl/shop/wi-fi-p1-meter/ This meter also exposes an API on the local network. I have written a small driver for the SmartThings Hub, so that you can get the stats/graphs in the SmartThings app as well (we use a SmartThings hub for Zigbee/Z-Wave devices): https://github.com/danieldk/homewizard-energy https://github.com/danieldk/homewizard-energy

This applies to Finland and Sweden too, perhaps others to follow.

  Same principle in Norway, though it uses HAN instead of P1.

    They call it HAN here in Finland too, but it's the same interface as the Netherlands one.

Same in France, the official meters have an interface on which you can plug a Raspberry Pi for example to read the data live.

Do you know of an equivalent for the optical ports that speak DLMS/COSEM? The P1 standard doesn't seem to have caught on here in Spain just yet.

It seems that nl ppl always live 20 years into the future.

> all Smart Meters that the net maintainers installed (are required to) support the P1 standard Does that support monitoring each power circuit separately?

  Not likely, you’d need a CT around the phase conductor(s) of every circuit. The meter likely only has CTs around the 2 (3) phase conductors on the incoming service drop. It is entirely possible to meter each individual circuit, either with CTs and a meter or (gross simplification) special breakers that have metering capability built-in.

Indeed it is great to use what is already provider by the utilities company, for the same reason I wrote a prometheus exporter that exposes the homewizard values https://github.com/chrisdoc/homewizard-p1-prometheus https://github.com/chrisdoc/homewizard-p1-prometheus

Or to integrate with home assistant and cheaper https://www.zuidwijk.com/product/slimmelezer-plus/ https://www.zuidwijk.com/product/slimmelezer-plus/

I guess I will be able to get this cheap when we finally have smart meters in Germany in like 20 years
