Build HEMS
on Hardware
You Already Know

You already build images for ZGEMMA boxes. The AI-Energy Box is the same platform — Amlogic S905Y4, running OpenPLi, OpenViX or OpenATV — with one addition: a USB RS485 bridge that connects to solar inverters, EV chargers and smart meters.

We need Enigma2 community developers to build open-source HEMS plugins. We will send you the hardware for free.

AI-Energy Box + USB RS485 Bridge
We ship the complete dev kit to your door at no cost. No strings attached beyond contributing your plugin back to the community as open-source.

Your Plugin, Your Credit
Everything you build is published on zgemma.org as a free download for the whole Enigma2 community. Full authorship credit to you.

Learning Curve on the Linux Side
OpenPLi, OpenViX, OpenATV — you built these images. Same Python plugin framework. Same Enigma2 APIs. Just a new hardware interface to talk to.
Same Box.
New Capability.

The AI-Energy Box is not a new platform to learn. It is the ZGEMMA hardware you already work with, running the same Enigma2 Linux stack you know inside out.

The only addition is a USB 2.0 → RS485 bridge that exposes a standard serial interface to industrial energy devices — solar inverters, battery systems, EV chargers and smart meters using Modbus RTU, SunSpec or OCPP.

Your Python skills, your plugin knowledge, your image build process — all of it transfers directly.

What We Need Built
☀️
Modbus RTU · SunSpec
Solar Inverter Monitor
Read live generation data from solar inverters via Modbus RTU or SunSpec. Display power output, daily yield and fault status as an Enigma2 plugin. Compatible with SMA, Fronius, Huawei, Growatt and other major brands.
🔋
Modbus RTU
Battery Storage Dashboard
Monitor home battery state-of-charge, charge/discharge rate and grid import/export via Modbus. Show real-time energy flow: solar → battery → grid → home. Supports BYD, Pylontech, LG Chem and other systems.
⚡
OCPP 1.6J
EV Charger Controller
Control residential EV chargers via OCPP. Start/stop charging, set charge rate, view session history and enable time-of-use scheduling — all from the TV interface via your set-top box.
📊
All Protocols
Home Energy Overview
A combined dashboard aggregating solar, battery, EV and grid consumption into a single Enigma2 screen. Show today's self-sufficiency rate, cost savings and carbon offset in real time.
🌡️
Zigbee · P1/DSMR
Smart Meter Integration
Read P1/DSMR smart meter data (Netherlands, Belgium) or Zigbee energy monitors. Display live grid consumption, peak demand and hourly usage history directly from the set-top box.
