Intelligent Energy Management · Local · Real-time
Your energy system.
Locally connected.
GridFusion connects solar, storage, home and the grid into an intelligent overall system — increasing self-consumption, lowering electricity costs and providing full control over your energy.
Local Control Dynamic tariffs Solar forecast No mandatory cloud
Decide locally
Verify measurement values and act safely and traceably only when the state is valid.
Plan Ahead
Evaluate solar forecasts, electricity prices, consumption and storage together.
Maximize self-consumption
Coordinate energy surpluses and grid consumption to match the current energy flow.
Use electricity prices intelligently
View tariffs, battery level and solar production together.
Connecting systems
Consolidate measurement, storage and forecasting locally.

How GridFusion works
From the measured value to a reliable decision.
Control 7 connects existing components, translates their data into a shared energy model, and makes decisions locally. Prices and forecasts supplement this model but never assume local control.
- 01
Record energy
Meters, inverters, PV system and battery storage provide their available measurement data via separate device drivers.
Local preferred · vendor-neutral normalized - 02
Check status
GridFusion verifies recency, plausibility, battery level and system state. Stale or invalid measurements do not trigger a new battery command.
Fail-safe · traceable states - 03
Plan ahead
Self-consumption, available battery capacity, variable pricing intervals and the expected solar generation are evaluated jointly.
Price and forecast data remain optional - 04
Operate within limits
A control decision is executed only locally, with ramps, SOC limits and a central Safety Gate. Without explicit authorization, Solakon write access remains locked.
Remote requests verified locally · no Safety-Gate bypass
The heart of the system
A system.
Four energy flows.
Solar, battery, house and grid are not considered separately. GridFusion integrates their data in real time and makes decisions based on the overall energy state.
- Shared local energy model
- Measured values and states in real time
- Traceable decisions

Control 7 in motion
The real device interface. Not a replica.
The Windows simulator renders the same LVGL interfaces as the ESP32-S3 device. The demo shows the dashboard, pricing, history, controls and system views without access to real hardware.
- Pixel-accurate output at 800 × 480
- Reproducible scenes and image sequences
- Ensure: no hardware commands in the simulator
Hero-Replay uses anonymized, normalized energy values. Device identifier, location, and original timestamp are not included; other displays are simulation values.
Video description
The 30-second demo sequentially shows the local Control 7 dashboard with energy flow between solar, battery, house and grid, the electricity price and trend views, a secured control view, and diagnostics and system status. All scenes originate from the reproducible Windows simulator; it cannot send hardware commands.

Dynamic tariffs
Use electricity when prices are low.
GridFusion can identify low-cost electricity periods and reconcile them with battery capacity, expected consumption, and the solar forecast. That way charging is not simply cheap — it is sensibly planned.
- Detect cost-effective charging windows
- Avoid costly hours
- Account for battery efficiency
- Reserve space for solar yield
Forecasting & Planning
GridFusion thinks beyond the immediate moment.
A good energy manager does more than react. It takes into account what is likely to happen next — for example, favorable price windows or expected solar production.

Local First
Your energy stays with you.
The central measurement and regulation take place on the local network. Local self-consumption control remains operational even without an Internet connection.
- Local network control
- No mandatory cloud dependency for control
- Local operation during Internet outage
- Local history and diagnostics

GridFusion HMI
A display you want to look at.
The 7-inch touch display makes GridFusion directly operable on-site. Energy flow, storage, prices, forecasts and system state are visible without a smartphone or cloud portal.

Illustration and technical implementation reflect the current development status and do not yet constitute a commitment to series production.
Modular and extensible
Open to your energy system.
The first target platform connects Shelly Pro 3EM and Solakon ONE. Additional devices and interfaces can be added via clearly separated adapters.
Shelly Pro 3EM
Three-phase energy measurement as a local data source.
Solakon ONE
Battery storage for coordinated charging planning.
MQTT
Open data exchange within the local network.
Home Assistant

Wallbox
Integrate PV- and price-optimized charging.
Heat pump
Plan flexible loads intelligently.
Features
An energy system that understands interdependencies.
Self-consumption optimization
Detect solar surpluses and coordinate battery storage to match actual household consumption.
Dynamic tariffs
Assess price windows not in isolation, but together with storage, consumption and forecast.
Solar forecast
Take expected generation into account and proactively reserve battery capacity.
Battery planning
Plan charging targets and time windows in a comprehensible way, rather than merely reacting to the current measured value.
History & Analysis
Locally trace energy flows, states and decisions and perform technical diagnostics.
Local API & Integration
Securely integrate cross-vendor components via clearly separated adapters.
Transparently developed
What works — and what comes next.
GridFusion is an advanced development and pilot system, not yet a finalized, released production product. For that reason we keep the currently implemented state clearly separated from ongoing hardware tests and planned extensions.

- Local history, diagnostics and configuration
- Centralized pricing, weather, forecasting and OTA integration
- Secured Solakon control path behind central Safety Gate
Try it now
- Monitor additional systems and non-standard device combinations
- Use only drivers from verified manufacturer sources.
- Controlled write tests initially under a tight performance limit
- Extend failure, router, storage, OTA and long-term tests
- Compare forecasts and decisions with actual outcomes
Then extend

Important: Cloud services supplement data and convenience. Measurement, the Energy Engine and security decisions remain local; a central platform cannot circumvent the Solakon Safety Gate.
FAQ
Key information on GridFusion.
GridFusion is under development. Features and integrations are communicated transparently according to the actual status.
What connects GridFusion?
Solar generation, battery storage, household consumption, grid imports, dynamic electricity prices and forecasts are integrated into a local energy model.
Does the control system require a cloud?
Central measurement and control are intended to be local. External services are used only where price or weather data deliver a concrete benefit.
Which devices are supported?
Shelly Pro 3EM and Solakon ONE constitute the initial target platform. Additional integrations are planned and will be marked as available only after technical availability.
Is the display already in series production?
No. The hardware shown reflects the current state of development and does not yet constitute a binding offer for series production.
