Temperature Alarm Design: Detect, Acknowledge, Recover, and Audit
A freezer warms briefly during restocking and sends repeated alerts. Later, a genuine high-temperature incident disappears from the dashboard when someone clicks.

Rockchip Dev Board vs SoM vs Carrier Board: How to Choose
A development board, SoM, and carrier board are not performance tiers. Choose the right Rockchip path for PoC, EVT, DVT, PVT, and production.

When an RK3566 AIoT Gateway Is Enough for Lightweight Edge Computing
Select an RK3566 AIoT gateway by deadlines, CPU/NPU/memory/I/O contention, sustained load, degradation, and recovery—not 1 TOPS or a short demo.

Permission Models for Multi-Tenant Device Management: Why RBAC Is Not Enough
The most dangerous authorization defect in a multi-tenant device platform is rarely a missing menu permission.

Asset Model vs Telemetry Schema: How to Separate the Contracts
An industrial asset model and a telemetry schema should not share one lifecycle. The asset model answers what an entity is, where it belongs.
