A complete Home Assistant energy monitoring kit built around a Raspberry Pi 4 and Eastron SDM230 Modbus energy meter. Designed for customers who want a practical DIN rail-mounted setup for real energy measurement, dashboards, and automation. Supplied from UK stock with fast dispatch.

This kit provides everything required to add real energy monitoring to Home Assistant.

Instead of relying on estimated power usage, the included Eastron SDM230 Modbus energy meter measures real electrical consumption directly from your electrical supply.

Combined with a Raspberry Pi 4, this setup allows Home Assistant to display detailed energy dashboards, monitor solar production, track EV charging, and analyse household or sub-metered energy use.

It is a practical kit for Home Assistant users building a more complete energy monitoring setup.

Please note: this is a hardware kit for customers building their own Home Assistant monitoring system. It is not a fully plug-and-play consumer appliance.
