I recently configured a custom sensor to monitor energy consumption using the SlimmeLezer+ device. This setup has been incredibly helpful in understanding my energy usage patterns. I reused some C code from Forsberg’s GitHub repository to create a custom sensor for my Romande Energie AM550 meter. The process involved setting up the device to read DSMR P1 data and integrating it into my Home Assistant setup. I found the code adaptable and it provided the necessary data points such as cumulative active import/export and voltage/current readings. The integration was seamless, and the sensors now provide real-time data which helps in optimizing energy consumption. I would recommend this approach to anyone looking to gain deeper insights into their energy usage without relying on third-party apps. The ability to customize the sensor to fit specific needs is a significant advantage. If anyone has questions or needs assistance with similar setups, feel free to reach out!
