How to Setup Sonoff Smart Switch Architecture Infographic

Tech architecture infographic titled "Smart Lock Install". Use archetype: SYSTEM ARCHITECTURE adapted as a network topology diagram for a smart-home installation flow. Create a clean top-down / slight isometric blueprint schematic showing labeled boxes and device nodes connected by arrows with clear data direction. Include these components as boxed modules with generic icons, English names, and one-line English role descriptions: 1) Smartphone App — "Mobile setup interface for pairing and configuration"; 2) Home Wi-Fi Router — "Local network gateway providing IP connectivity"; 3) Smart Home Hub — "Optional controller bridging local automation protocols"; 4) Smart Lock — "Battery-powered door lock with wireless control and status sensing"; 5) Door Sensor — "Reports door open or closed state"; 6) Keypad / NFC Reader — "Accepts PIN code or tap credential for local unlock"; 7) Bluetooth LE Link — "Short-range pairing channel during installation"; 8) Cloud API — "Remote management, device registration, and event sync"; 9) User Account Service — "Stores user identity, permissions, and shared access"; 10) Notification Service — "Delivers lock, unlock, tamper, and low-battery alerts". Show arrows with short English labels such as: "BLE pairing", "Wi-Fi setup", "HTTPS device registration", "OAuth login", "access policy sync", "lock status", "battery level", "PIN credential", "door state event", "push alert", "remote unlock command", "ACK 200 OK". Make the flow technically accurate: Smartphone App pairs to Smart Lock over Bluetooth Low Energy for first-time provisioning; app sends Wi-Fi credentials or hub binding settings securely; Smart Lock connects either to Smart Home Hub or directly via router depending on topology; Hub or lock communicates with Cloud API over HTTPS/TLS; User Account Service authenticates app session with OAuth and issues access token; Cloud API returns 200 OK for successful registration; Notification Service sends event-driven push notifications after lock/unlock or tamper events. Emphasize installation steps visually: mounting lock on door, inserting batteries, pairing by BLE, joining network, calibrating lock direction, testing keypad / sensor, enabling remote access. Add small callout boxes for physical install checks: "Mount interior assembly", "Align deadbolt", "Insert batteries", "Run calibration", "Test manual lock", "Verify wireless signal". Include a numbered legend 1-7 in English walking through the lifecycle: 1) Install lock hardware on the door and insert batteries. 2) Open the mobile app and authenticate with OAuth login. 3) Pair the phone to the lock using Bluetooth LE. 4) Send network or hub configuration to the lock securely. 5) Register the device with the cloud service over HTTPS. 6) Sync users, PIN codes, and automation permissions. 7) Test local unlock, remote control, and event notifications. Visual style: blueprint schematic, green smart palette, dark blueprint background with neon green lines, mint highlights, white technical labels, subtle grid, circuit-like connectors, precise vector outlines, calm high-tech DIY mood. Composition should resemble an editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout. Use generic cloud, router, smartphone, door, lock, keypad, battery, and shield icons only; no real smart-home brand logos. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real cloud-vendor logos (AWS / GCP / Azure) — use generic cloud icons, no watermarks No real smart home brand logos (no Google Home / Alexa / HomePod). Generic icons.
