Description
Complete home energy management system combining data from Victron Venus OS, Shelly Pro 3EM energy meter and JK-BMS battery management. The dashboard shows energy flows in real-time and calculates electricity costs/savings. All data is received via MQTT, stored in MongoDB and streamed live to the browser frontend via WebSockets.
Safety note: Rebuilds at your own risk. This description is a personal documentation, not a verified build guide, and the values given are experience-based estimates without any guarantee. Details under Disclaimer (German).

Smaller projects along these lines are available as the "IoT Web Dashboard" package from 399€. A project of this size I quote individually, just get in touch.
I deliver software only (firmware, configuration, code) — no assembled hardware. The components used are only linked for reference, you buy them yourself. Enclosures on request.
