Hungary Adopts Smart Electricity Meters: Monitor Energy Usage with Home Assistant

In Hungary, the adoption of Smart Electricity meters has been ongoing for some time. With the implementation of these advanced meters, individuals can effectively monitor the energy consumption of their homes by leveraging the capabilities of Home Assistant. It is important to note that every Hungarian smart meter adheres to the DSMR standard, originally developed in the Netherlands, utilizing a P1 port for connectivity. By utilizing this port, users can establish a connection with a smart meter gateway, enabling access to the data to get insight in their energy usage and production. With this information you are able to efficiently use your energy for costs savings.

One notable benefit of employing Home Assistant is the ability to gain valuable energy insights. This user-friendly platform provides a comprehensive and visually appealing dashboard, presenting users with all the essential information they require. Additionally, for individuals with solar panels installed, the Hungarian smart electricity meters also provide outputs related to solar panel performance.

By combining the power of Smart Electricity meters, Home Assistant, and solar panel integration, people in Hungary can effectively manage and optimize their energy usage, ultimately leading to more sustainable and efficient energy practices.

Gas usage also visible

Smart Gas meters are being installed in Hungary too, just like their electricity counterparts. When gas meters are equipped with smart capabilities, they can efficiently transfer gas usage data to smart electricity meters. This data exchange is made possible through the use of a reliable radio link, which opens up exciting possibilities, including the ability to publish this valuable information to the popular Home Assistant platform. With the Smart Meter Gateway from Smart Gateways it’s possible to monitor your gas consumption with Home Assistant too.

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