More Than Just An App
The SwitchMaster application is only one implementation of the wider SwitchMaster platform.
As part of the open-source release, users and developers are free to modify the existing application, add new functionality, create their own versions or build entirely new interfaces tailored to their specific requirements.
Whether you're building a custom vehicle dashboard, integrating with an existing monitoring system or creating a completely new user experience, the platform gives you the freedom to do so.
Open Development
The official SwitchMaster application remains available as a reference implementation of the platform.
However, the real strength of an open platform is that you're not limited to a single application, feature set or development roadmap.
Developers are free to:
-
Modify the existing application
-
Create their own mobile applications
-
Build custom dashboards
-
Integrate with Home Assistant
-
Develop Raspberry Pi solutions
-
Build commercial products
-
Integrate with fleet management systems
-
Create entirely new user experiences
Whether you're looking to add features, customise the user experience, integrate with third-party platforms or develop a commercial product based on the SwitchMaster ecosystem, the platform provides the flexibility to do so.
MLT Industries may also be able to assist with custom development, integrations, branding opportunities and commercial implementations depending on project scope and availability.
Open Source Platform
The SwitchMaster ecosystem includes:
-
Firmware source code
-
Mobile application source code
-
Communication protocols
-
PCB design files
-
Schematics
-
Hardware design files
-
Enclosure and case files
-
Development documentation
Nothing is locked away behind proprietary interfaces or closed APIs.
Future-Proof By Design
Many modern vehicle control systems rely on proprietary applications, cloud services or closed ecosystems.
SwitchMaster takes a different approach.
By making the platform open source, users retain control of their hardware and software. The platform can continue to evolve, be maintained and be improved regardless of what happens to any individual company or developer.
Own The Hardware. Own The Software. Own The Future.
The goal of the SwitchMaster platform is simple:
Give users complete control over their installations without subscriptions, cloud dependency or vendor lock-in.
Use the official application, modify it, build your own or integrate SwitchMaster into something entirely different.
The choice is yours.
