  • For reference: smart meters like Kamstrup are in use all over the EU. Example of a p1 dongle is the “smart meter gateway” which can be read from home assistant via the DSMR integration or directly from mqtt.

    This would give you the counters for exactly how much you have pulled from and pushed into the grid.

    Can confirm this will integrate nicely into the energy dashboard.

    And biggest tip: when you have configured everything, it will take up to 2 hours before any data is visible from the energy dashboard. This screwed me over quite a bit, needless to say :-)


  • Look up your inverter brand and pray there is an integration for it. Also: try to make your electrical meter smart to be able to tell the difference between pulling from grid and delivering to grid. If you already have a smart meter, see if it exposes some interface (like P1 with the DSMR protocol for example) to easily integrate the meter into home assistant.

    I have done all this with a goodwe inverter and a kamstrup meter P1 port using a DSMR dongle.

    If you need any pointers, dm me.
