How to Setup Google Home Thermostat Comparison Infographic

Tech architecture infographic titled "Voice Assistants Compared" using archetype HOW-IT-WORKS adapted as a protocol comparison chart. Create a side-by-side comparison of 3 generic voice assistant ecosystems for smart home control, shown as parallel labeled BOXES and ARROWS in a dark mode developer layout. Column 1: "Assistant A" with microphone/speaker icon, role description "Captures voice commands and triggers smart home actions". Column 2: "Assistant B" with voice orb icon, role description "Processes requests and manages connected devices". Column 3: "Assistant C" with smart speaker icon, role description "Handles automation, queries, and device control". Below each assistant, show connected component boxes: "Mobile App" with phone icon, role description "Pairs devices and manages home settings"; "Cloud API" with cloud icon, role description "Authenticates users and routes commands"; "Home Hub" with hub/router icon, role description "Bridges local devices and automations"; "Thermostat Device" with thermostat icon, role description "Receives temperature setpoints and reports status". Connect boxes with ARROWS showing data direction: from User voice input to Assistant labeled "Voice command"; Assistant to Cloud API labeled "HTTPS request"; Cloud API to Home Hub labeled "Device command"; Home Hub to Thermostat Device labeled "Zigbee / Thread / Wi-Fi"; Thermostat Device back to Hub labeled "Temperature state"; Hub back to Cloud API labeled "Device telemetry"; Cloud API back to Assistant labeled "JSON response"; Assistant back to User labeled "Voice confirmation". Include small comparison metric boxes under each column: "Setup flow", "Local control", "Cloud dependency", "Automation support", "Device compatibility", with simple neutral comparison indicators, all text in English. Add a centered top comparison header row with generic protocol/support labels such as "Wake word", "HTTPS", "OAuth 2.0", "Matter / Thread", "App pairing". Add a numbered legend (1-7) walking through the request lifecycle in English: 1. User speaks a thermostat command. 2. Assistant performs wake-word detection and speech recognition. 3. Cloud API authenticates account and checks permissions. 4. Command is translated into a thermostat setpoint action. 5. Home hub forwards the action over Zigbee, Thread, or Wi-Fi. 6. Thermostat applies the change and returns current state. 7. Assistant confirms success or reports an error such as HTTP 200 OK or device offline timeout. Emphasize comparison of setup and control flow for smart thermostat onboarding and command execution, but do not include brand logos. Visual style: editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout. Use dark mode UI panels, cool tech blue palette with cyan highlights, slate background, soft neon outlines, crisp grid alignment, subtle glow, professional and analytical mood. Include generic 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.
