Infographie google home : gestion d’une maison connectée

Tech architecture infographic titled "How Google Home Manages a Smart Home" using HOW-IT-WORKS archetype, shown as an isometric 3D modern house floor plan with room-by-room automation flows. Center the composition on a generic Voice Control Hub box in the cloud/control layer, with heading text allowed to reference Google Home only in titles and section headings, but all product visuals must be generic and non-trademarked. Render labeled boxes connected by directional arrows across the house: Smartphone App — 'Mobile Controller' — 'User sends commands and views device status'; Smart Speaker — 'Voice Assistant Speaker' — 'Captures voice commands and plays responses'; Living Room Lights — 'Smart Lighting' — 'Receives on/off and brightness scenes'; Thermostat — 'Smart Thermostat' — 'Adjusts temperature and HVAC schedules'; Security Camera — 'Security Camera' — 'Streams video and motion events'; Front Door Lock — 'Smart Lock' — 'Handles lock and unlock actions'; Kitchen Appliance — 'Connected Appliance' — 'Executes scheduled or remote actions'; Home Router — 'Wi‑Fi Router' — 'Connects local devices to internet'; Cloud Service — 'Voice Control Hub' — 'Processes intent, automation rules, and device orchestration'; Automation Engine — 'Routine Engine' — 'Triggers multi-device scenes and schedules'; Notification Service — 'Alert Service' — 'Sends status updates and security alerts'. Use arrows with short English labels: 'Voice command', 'HTTPS request', 'Intent data', 'Device state sync', 'Wi‑Fi control', 'RTSP/HLS video stream', 'Lock command', 'Temperature setpoint', 'Scene trigger', 'Push notification', 'JSON response'. Show technically accurate flow: user speaks to smart speaker, audio/intent sent over HTTPS to cloud voice control service, automation rules evaluated, commands dispatched via home router over Wi‑Fi to local devices, devices return state updates, camera sends encrypted stream metadata and video path, app receives push notifications and status via HTTPS. Add clean callouts per room: Living Room, Kitchen, Entryway, Hallway, Bedroom, Utility Area. Include numbered legend 1-7 in English: 1. User issues a voice command or app action. 2. Smart speaker or mobile app sends HTTPS request to the voice control cloud. 3. Voice Control Hub interprets intent and authenticates account/device context. 4. Routine Engine checks schedules, scenes, and automation conditions. 5. Commands are sent through the home network to lights, thermostat, locks, appliances, and cameras. 6. Devices execute actions and return state updates or event data. 7. App and speakers present confirmations, live status, and alerts to the user. Visual style: photorealistic yet editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout, modern smart-home explainer, precise clean callout lines, subtle UI overlays, glossy but readable device renderings, cool tech blue palette with white and cyan highlights, calm futuristic mood, premium magazine-quality composition. All text rendered cleanly in English, no spelling errors, no gibberish characters, 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.
