About this gig
RS-485, Smart Lock & Industrial Hardware Integration
Need your mobile app to communicate directly with real hardware smart locks, vending machines, or industrial control boards? I specialize in RS-485 protocol integration, connecting Android apps directly to physical devices for real-world control and monitoring.
Experience with:
- Smart lock systems multi-position lock boards with multi-channel unlock control
- Vending machine & kiosk board integration with real-time polling
- Industrial device communication (motor control, temperature monitoring, status feedback)
What I can build:
- RS-485 driver communication setup between your app and hardware
- Multi-channel unlock / lock control systems
- Real-time device polling and status monitoring (run, acknowledge, scan, temperature commands)
- Native SDK integration for direct hardware communication
- Live device dashboards showing connection and status
Perfect for:
- Smart lock / access control products
- Vending machine and kiosk manufacturers
- Warehouse & industrial equipment monitoring
- Property management / rental access systems
- Custom IoT hardware startups

FAQ
Do I need to provide the hardware/board for you to work with?
Yes — for RS-485 integration, I'll need either physical access to the device/board or its technical documentation (command protocol, communication specs) so I can build accurate communication with it.
What types of hardware have you worked with?
Smart lock systems (multi-position lock boards), vending/kiosk machine boards, and industrial control boards using RS-485 protocol for polling, unlock control, and status monitoring.
Can you work with hardware I haven't listed, or custom/proprietary boards?
Yes, in most cases — RS-485 is a standard protocol, so if you can share the command documentation or SDK for your specific device, I can build the integration. Message me first with details so I can confirm feasibility.
Do I need an existing mobile app, or can you build one from scratch?
Both. If you have an existing app, share repository access and I'll integrate the hardware communication into it. If not, I can build the full app around the hardware integration.
How do revisions work for hardware integration projects?
Each package includes a set number of revisions. Since hardware testing sometimes requires back-and-forth as we confirm behavior on your actual device, I recommend using the Milestones workflow so we can validate each stage together.
Do you provide source code?
es, full source code is included in every package so you retain complete ownership.
What information should I share before ordering?
Your device/board model (if known), any technical documentation or SDK files you have, and whether you need a full app built or just the hardware communication module added to an existing one.
Can this integrate with a backend or monitoring dashboard?
Yes — I can sync device status and control data to a backend (Firebase, MongoDB, MySQL) and build a simple real-time dashboard if needed.
