Energy Meter

Energy Meter is a local-network Chrome extension for real-time monitoring of SMA Solar plants. It auto-discovers SMA devices on your LAN, shows live energy flow, per-phase measurements, and charts, all without cloud dependency.

Key capabilities include real-time data from SMA Energy Meter and MODBUS-enabled inverters, automatic device detection, and a clear view of grid consumption and self-consumption at the connection point. Ideal for self-consumption PV setups and Sunny Home Manager devices; note that long-term recordings are not supported.
