Gerätesteuerung, Live-Daten und Optimierung per REST-API. Für Hersteller und Plattformen mit eigenem Frontend.



The control backbone for your energy products
# one endpoint, every device GET /v1/users/{userID}/devices { "model": { "vendor": "Viessmann", "category": "heatPump" }, "capabilities": [ { "name": "display-power", "data": { "power": 1450 } }, { "name": "display-temperature", "data": { "temperature": 43.5 } } ] }
Whether you build devices or sell energy
Manufacturers
You build wallboxes, inverters, or heat pumps and want to offer energy management as software on top — without your own cloud team and without integrating third-party devices yourself.
Energy providers
You already have an app or a customer portal and want to add device control, live data, and optimization — without maintaining 80 manufacturer interfaces yourself.
Proven features, thousands of times over. Ready to integrate.
Live monitoring and control
Real-time values and direct control commands through a unified capabilities logic — no device hard-coding.
PV and load forecasts
Forecasts for generation and consumption over the next 48 hours — the data basis for optimization and procurement.
Energy communities
Community output is captured per household — the basis for energy-sharing models and shared billing.
Historical data
Daily profiles in 5-minute resolution, plus weekly and monthly aggregates — per device, including savings.
Solar and price optimization
Devices run automatically on solar surplus or dynamic tariff — as ready-made logic, not raw data.
Flexibility marketing
Controllable devices are made market-ready — you connect them to your procurement or trading process.
Device data becomes margin
Anyone who knows the flexibility of wallboxes, heat pumps, and storage can market it. The Connect API delivers customer-specific forecasts — to smooth procurement, anticipate load profiles, and bring controllable loads into your trading model.
Ihr bringt den energiewirtschaftlichen Prozess, wir liefern die Datenbasis und die User-Oberfläche dafür.


The difference is in the control
A storage system that only charges is a storage system. A storage system that knows when electricity is cheap, when the sun will come, and when the car needs charging is a product. That intelligence is what the Connect API delivers — fully optimized, not raw data to build yourself.
To make that reliable, we rely on official interfaces. EVs, for example, we connect directly through the manufacturer APIs of VW, BMW, and Tesla .
What your developers can expect
Protocol
REST, JSON, versioned under /v1/
SDKs
C#, Python, JavaScript
Authentication
OAuth2 Client Credentials
Abstraction
Unified capabilities
Live data
Push via Azure Event Hubs
Hosting
EU data centres, GDPR
Real-time without polling
Live telemetry: pushed, not polled
Instead of querying each device individually, you receive all device changes as a continuous stream in near real time. Ideal for dashboards and monitoring — and cleanly attributable per end customer.
Endpoints, auth flows, capability reference, and code examples
For developers: the complete documentation
80 protocols become one logic
Every manufacturer speaks its own language. One wallbox reports its charging status differently from the next, a heat pump differently again. Integrating them all would mean learning dozens of languages and constantly patching.
Instead, we translate every device into a shared language: the capabilities. Whether charging, showing power, or optimizing for solar — it all appears in the same format. You program once, and new manufacturers are added with no effort on your side.
