Frequently Asked Questions

Yes — we are a Smart IoT company that develops its own hardware. We design and build custom PCB and board-level hardware to fit each project, rather than only assembling off-the-shelf parts. We pair that with our own management platform and mobile apps, plus deployment and support, into complete industry solutions. We do not fabricate chips, modules or low-level semiconductors (the upstream layer); we work at the product level — custom hardware plus software.

To stay accountable, we keep clear boundaries: no chip, module or semiconductor fabrication (we design boards, not silicon); no consumer products; no software-less projects (every project pairs hardware with a management platform or app); and we do not take classified or military projects unless specially authorized. When something is outside our expertise, we say so plainly rather than over-promising.

REDCOAST.LTD is a focused team of engineers with complementary software and hardware backgrounds. We prefer to earn trust through a transparent process, clear quotes and verifiable deliverables rather than polished credentials. Talk to us about your specific project and we will be honest about what we can and cannot do.

Yes — customization is at the core of how we work. From hardware selection, power and communication options, to platform features, app UX and third-party integration, everything is tailored to your industry, scale and compliance needs. We do not simply re-badge someone else’s solution; every project is designed from scratch.

Because our value lies in the hardware-plus-software whole. Hardware alone leaves the customer with a pile of devices to operate themselves. Paired with our own web management platform and mobile apps, you get device management, real-time monitoring, data visualization and remote control — so the project is actually operable. That is why we decline hardware-only projects.

Flexible power design is one of our key differentiators. We combine multiple power options to match the deployment environment: grid power, solar, grid-solar hybrid, wind-solar hybrid, and battery storage. Whether on city roads, in remote areas or harsh outdoor conditions, we can provide a stable and reliable power design.

We choose the right communication option per scenario: cellular 4G / 5G, low-power wide-area NB-IoT / LoRa, wired Ethernet, and short-range WiFi. On the platform side we support standard protocols such as API, MQTT and HTTP for smooth integration with the customer’s existing systems, avoiding data silos.

Standardized solutions are typically delivered in 4–6 weeks. Projects involving custom hardware selection and platform / app development take 6–10 weeks depending on complexity. Before signing, we provide a clear quote, milestones and delivery schedule — all written into the contract.

Yes. We support international B2B projects with English communication, remote technical support, project-specific documentation and deployment planning. If on-site guidance, commissioning or training is needed, the scope is confirmed during the proposal stage based on project location, schedule and local requirements.

Hardware comes with a standard warranty and the software platform includes a free upgrade period. After the warranty, paid maintenance is available to keep the system running reliably across its full lifecycle. Exact warranty terms are confirmed in the contract based on the hardware selected and project scope.

Yes. Secondary development of the platform and apps is one of our standard services. Whether adding features, integrating a new third-party system, or supporting new hardware, we keep iterating on the delivered system — handled end-to-end by the same team.

We work in three main ways: integration project delivery (one-time payment plus maintenance), packaged hardware-plus-software standardized solutions, and platform / app secondary development services. We provide solution design and a quote for free before any contract; afterwards, one team owns everything from hardware to apps, with pricing, timeline and scope all agreed upfront.
