LLMs Are Not IoT Translators: Three Semantic Gaps in Practical LLM-IoT Integration

When integrating LLMs with industrial IoT devices, 90% of failures occur not at the API layer—but across three semantic gaps: misalignment between natural language and device command semantics, temporal distortion of time-series data in textual representations, and inability to synthesize heterogeneous alerts into executable decision chains. Based on six real-world production line deployments, this article exposes the most hidden—and critical—engineering blind spots.

Edge Computing Isn’t Just ‘Adding a Gateway’: Four Engineering Pitfalls in IoT Low-Latency Deployment

In manufacturing QA, AGV coordination, and energy alarms, end-to-end latency >200ms renders the system unusable. Based on ePPay’s field measurements across 17 industrial sites, this article exposes four overlooked engineering breakpoints: protocol tunneling distortion, timestamp inconsistency collapse, resource misallocation that increases overhead, and security policies that strangle real-time performance.
