Sweden is adopting Smart Electricity meters for a while. When you have such a smart meter, you can monitor the energy usage of your home with Home Assistant. Every Swedish smart meter is following the DSMR standard which uses a P1 port. This P1 port can be used to connect a smart meter gateway to make the data available for your own usage. One way to get some insights is Home Assistant. Home Assistant has a beautiful dashboard with all the information you need. The Swedish smart electricity meters also output the output of solarpanels if installed.

Gas usage also visible

Some gas meters are smart too. When they are, most of the times they transfer the gas usase to the smart electricity meter. They use a radio link for this. This makes it possible to also publish this data to Home Assistant

In this post I will tell you how to connect your smart meter from Sweden to Home Assistant.

What do you need to connect a Swedish smart meter to Home Assistant?
