Storcube S1000 Pro Zero Export Solar: Fixing Smart Meter Mode Using Shelly Pro 3EM and Raspberry Pi Kindle Edition

by Pat Klimesch (Author) Format: Kindle Edition

The Problem

The Storcube S1000 Pro officially supports Smart Meter mode with the Shelly Pro 3EM. However, in real-world installations this setup often fails to work correctly.

Why?

Because the Storcube app allows you to select only a single phase. In a typical three-phase household, the device therefore never sees the actual total power consumption of the house. This can lead to:

incorrect feed-in settings
unnecessary grid consumption
or even exporting power to the public grid when it shouldn't

This guide shows a simple and affordable solution to fix this limitation.

The Idea

With the help of a small Raspberry Pi, you can create a virtual smart meter called CubePI. CubePI reads the measurement data from the Shelly Pro 3EM, calculates the total household consumption across all phases, and provides this value to the Storcube exactly as if it came from a real smart meter.

Nothing is modified or manipulated.
CubePI simply delivers the correct data in the format the Storcube expects.

The result: near-perfect zero export control.
Setup time: about 30 minutes. No coding required.

What You'll Learn

This guide walks you through the entire setup step by step:

Why the Storcube Smart Meter mode does not work correctly in many installations
How to set up a Raspberry Pi in just a few minutes
How to install and configure CubePI
How Shelly Pro 3EM, CubePI, and the Storcube communicate with each other
How to correctly add CubePI to the Storcube app
How to update CubePI in the future

All steps are explained in a clear and beginner-friendly way, even if you have no prior experience with Raspberry Pi or Linux.

What You'll Need

Storcube S1000 Pro (or compatible devices such as the Xoro SPS 1124)
Shelly Pro 3EM Gen2
Raspberry Pi (for example a Raspberry Pi Zero 2 W)
microSD card

The required software will be installed automatically using a simple installer script.
