The open platform for connected recreational vehicles
We connect
what others just install.
OpenCamperCore is the open platform for connected recreational vehicles, self-builders, manufacturers and fleets.
Our Vision
The camping industry creates great products — but every system speaks its own language. Modern recreational vehicles don't need another silo solution, but a common platform.
Manufacturer-independent. Offline-capable. Future-proof. Made in Germany.
OpenCamperCore was not created to replace existing systems.
OpenCamperCore was created to connect existing systems more intelligently.
Because the future is not about more devices. The future lies in existing devices finally being able to talk to each other.
The Problem
- Too many apps
- Too many displays
- Too many manufacturers
- No common language
The Solution
- Central interface
- Open protocols
- Local control
- Modern integration
So funktioniert es
Ein Kern verbindet alle Systeme.
Heizung, Energie, Licht, Sensorik, Fahrzeugdaten — OpenCamperCore bringt bestehende Systeme zusammen und lässt sie miteinander sprechen.
Product Family
Four Products. One System.
Gateway Lite
The entry point into vehicle networking.
Connects heating, air conditioning, fridge and energy system in the living area with the OpenCamperCore app, the Victron GX and Home Assistant. One CAN port and two CI-Bus ports, for 12 V and 24 V systems. Ideal for a vehicle with one CI-Bus line.
- Truma, Alde, Eberspächer, Autoterm and more, see compatibility list
- Truma via CP plus without iNet Box (TIN bus)
- Victron GX: reads values, OCC devices in the VRM portal
- Home Assistant via your own MQTT broker
- RJ45 LAN and WiFi, updates over the internet
Ideal for: Retrofits · Panel vans · Compact recreational vehicles · Installers
Learn more →Gateway Nexus
The digital nervous system for modern recreational vehicles.
Everything the Gateway Lite does, plus more computing power, more buses and slots for extensions. For larger installations with several CAN networks or with Truma iNet X and Victron GX at the same time.
- 3× CAN, 3× LIN / CI-Bus, RS485 and Ethernet
- WiFi 2.4 + 5 GHz (Wi-Fi 6) on a dedicated radio chip
- Truma iNet X and Victron GX at the same time
- Ethernet directly to the Victron GX, even without a router (link-local) – works without WiFi
- 2 signal outputs and tilt sensor
- Slot for an LTE/GNSS module (in preparation)
Ideal for: Premium builds · Expedition vehicles · Vehicle manufacturers · Special vehicles

In preparationMore than a power distribution unit.
Distributes the 12 V of the leisure battery to fused outputs, switches pump, lights and load groups and reads tanks, temperatures and vehicle signals. Operated in the browser, in Home Assistant and with push buttons that switch even without software. In preparation: the hardware is finished, the firmware is still growing.
- 10 switched outputs, 16 monitored fuses
- Bistable relays, push buttons act directly on the relay
- 4 tank senders and up to 4 temperature sensors
- Truma via CP plus without iNet Box (field test pending)
- Web interface, Home Assistant and MQTT
Ideal for: Complete builds · Vehicle manufacturers · Truma vehicles with CP plus · Home Assistant users

Coming soonEight lighting circuits, one module.
Lighting module with eight dimmable outputs for 12 V lighting circuits and one auxiliary output. Controlled over the CAN bus (250 kbit/s, VE.Can): by the OCC Gateway Nexus or directly by the Victron GX via Victron Digital Switching. Control is implemented; we are waiting for Victron to approve the protocol.
- 8 lighting outputs, dimmable, each with its own ground contact
- On the Victron GX VE.Can, listed with the switches, no extra software (Victron approval pending)
- Device ID via DIP switch
- App and Home Assistant via the Gateway Nexus
- 8 button inputs (planned: short press switches, hold dims)
Ideal for: Interior lighting · Ambient lighting · Reading lights · Exterior lighting

Open configuratorConsulting & Custom Development
We connect — on your behalf too.
OpenCamperCore is more than a product — it is the connecting layer between systems. We offer this exact expertise as a service too: we consult, integrate and develop individual solutions together with manufacturers, conversion workshops and fleet operators.
Custom Integrations
Specialist devices, manufacturers and bus systems cleanly connected.
Custom Development – Hardware & Firmware
Customer-specific control units, firmware and OEM solutions.
Consulting & Concept
Technical consulting and system architecture from the start.
Software & Visualisation
Web interfaces, app connectivity, Home Assistant, Node-RED, dashboards.
Victron Professional Integration
Victron energy systems cleanly integrated into the overall system.
OpenCamperCore is not really hardware. The hardware is just the visible tip.
The camping industry creates great products — but each speaks its own language. OpenCamperCore connects these worlds.
Technology
A common language for the whole vehicle.
Supported technologies: CAN, LIN, CI-BUS, RV-C, RS485, MQTT, Home Assistant, Victron, Node-RED, ESPHome, OTA Updates, Webinterface, Offline-first.
What makes OpenCamperCore — each feature explained:
Beta Program
Develop together. Get better together.
- We develop together with beta testers.
- Every vehicle is different, every build is different.
- Real users help with real requirements.
- Goal: an open, practical interface.
OpenCamperCore was not developed because the world needs another control unit.
OpenCamperCore was developed because the best systems in the world should finally be able to talk to each other.
