Zircon3D allows you to visualize not only raw sensor data, but also custom computed values using tools like Home Assistant template sensors. This guide shows how to create a Temperature Delta heatmap, but the same approach works for any custom metric. What is “Pre-Processed Data”? Pre-processed data means: Data that is calculated or transformed before visualization Examples: Temperature Delta (current vs target) VPD (humidity + temperature) Energy efficiency metrics Custom scoring or alerts Step 1 Create a Template Sensor In Home Assistant: template: - sensor: - name: "Living Room Temperature Delta" unique_id: "living_room_temperature_delta" unit_of_measurement: "°C" state: > {{ ( state_attr('climate.living_room', 'current_temperature') - state_attr('climate.living_room', 'temperature') ) | abs | round(1) }} Repeat for other rooms with consistent naming. Step 2 Create a Heatmap in Zircon3D Add a new heatmap layer Name it (e.g., Temperature Delta) Select your template sensors Step 3 Use Matching Rules (Recommended) To scale easily across rooms: Use a rule like: uid contains temperature_delta This automatically includes all matching sensors. Step 4 Configure Color Mapping Example: 0°C → Green (good) 3°C → Yellow (moderate) 5°C → Red (needs attention) Lower values = better comfort Step 5 Assign Devices to Floorplan Place climate/HVAC devices in your 3D layout Or update existing ones to use the heatmap Step 6 View the Heatmap Switch to the heatmap layer to see your data visualized in 3D.

Turn Derived Data into Real Spatial Insight with Zircon3D Understanding how well your HVAC system performs is not just about reading temperatures, it’s about seeing how conditions vary across your entire space. With Zircon3D, you can go beyond raw sensor data and visualize derived values like Temperature Delta directly on your 3D floorplan. What is Temperature Delta? Temperature Delta = |Actual Temperature − Target Temperature| This value shows how far each area is from its desired condition: Small difference → Comfortable & balanced Large difference → Struggling to reach target Why this matters A Temperature Delta heatmap helps you instantly identify: Rooms that are too slow to heat or cool Areas with poor airflow or distribution Zones affected by insulation or layout issues Imbalance across floors or large spaces Instead of guessing, you can see the problem in seconds. Example: Temperature Delta Heatmap [image: 1776097180916-fd3ffdff-b9c8-46d9-906d-74a8865fb7a5-2026-04-13-13_10_29-2026-04-13-13_09_22-sticky-notes-new-copy-resized.png] In this example: The bedroom shows a 4°C difference, highlighted in orange/red which indicating the room is struggling to reach its target temperature. Nearby areas around 3°C (yellow) suggest moderate deviation. Green zones (0–1°C) indicate rooms that are well balanced and comfortable This kind of visualization makes it easy to spot HVAC distribution issues at a glance, especially in multi-room layouts. From Raw Data to Insight This example highlights a powerful capability of Zircon3D: You can visualize computed data, instead of just raw sensors Using a template sensor in Home Assistant, you can define your own metrics, such as: Temperature Delta heatmap (this example) VPD (Vapor Pressure Deficit) heatmap for greenhouses Energy usage heatmap per area Occupancy density heatmap Air quality indicators Then, render them as a 3D heatmap. Key Features Demonstrated ️ Support for user-defined data (template sensors) ️ Flexible entity matching (e.g., by name prefix) ️ Real-time 3D heatmap visualization ️ Works with existing HVAC / climate entities ️ Scales easily across multiple rooms How It Works 1. Create a Template Sensor in Home Assistant template: - sensor: - name: "Living Room Temperature Delta" unique_id: "living_room_temperature_delta" unit_of_measurement: "°C" state: > {{ ( state_attr('climate.living_room', 'current_temperature') - state_attr('climate.living_room', 'temperature') ) | abs | round(1) }} This calculates the difference between current and target temperature, and ensures it is always positive and easy to visualize. 2. Create a Heatmap in Zircon3D Add a new heatmap layer (e.g., Temperature Delta) Select your template sensors Use matching rules (e.g., uid contains temperature_delta) to automatically include multiple rooms 3. Configure Color Range Example: 0°C → Green (good) 3°C → Yellow (moderate) 5°C → Red (needs attention) Lower values indicate better comfort. 4. Assign Devices to the Floorplan Place your HVAC / climate devices in the 3D view Or update existing devices to use the new heatmap 5. View the Result Switch to the heatmap layer and instantly see temperature differences across your space. Why This is Powerful This is more than a visualization, it’s a data-driven spatial analysis tool. You are not limited to built-in metrics. With Zircon3D, you can: Define your own logic Compute custom values Visualize them in 3D space Turning your system into a true 3D data dashboard Learn More Get started with Zircon3D: https://zircon3d.com Documentation: https://zircon3d.com/docs Community forum (support & discussions): https://forum.zircon3d.com YouTube tutorials: https://www.youtube.com/@Zircon3D Join our Facebook group (updates & previews): https://www.facebook.com/groups/zircon3d What’s Next?

@Vagelis-Melidonis Hi, Yes, your solution is correct The Floating Cards mode is controlled by the View Profile, which is the right place to store your preferred settings for daily use. In the Designer, it will always fall back to the system default settings. We know this can be a bit confusing, and we may improve this in the future (for example, allowing it to be set via the URL). Let us know if you have any questions

@haoxian2023 Glad it is working now! Good job!

@Nima-Hamed Thanks for the reply! Tuya is great to know, that helps us a lot when planning support. Regarding the touch experience: in our latest version, we’ve introduced a Control panel designed for touch devices (please see the attached screenshot). This is a temporary solution to improve usability on phones and tablets. If you don’t see the control icon in the bottom bar, please make sure your add-on is updated to the latest version. We agree that touch interaction is very important, and improving it is definitely on our roadmap. We’ll continue refining the experience and adding more touch-friendly features in future updates. Thanks again for your feedback![image: 1774371316899-cff316b0-19f7-40fb-adae-3d6de016e816-image.png]

Hi, unfortunately we don't have this feature currently. But that's an interesting idea and we do have this feature in our backlog, we will add it in near future, please stay tuned.

A common question from new users is whether Zircon3D requires a cloud connection to run. The short answer is no, Zircon3D is designed to run locally. Local Operation All core functionality of Zircon3D runs locally inside your Home Assistant add-on, including: 3D floorplan modeling Real-time data visualization Heatmaps and dashboards Sensor monitoring Device interaction and controls Zircon3D reads data directly from your Home Assistant instance, so your monitoring and visualization continue to work even without external services. Your data and floorplans remain stored locally on your system. Zircon3D Account and Licensing To use Zircon3D, you will need a Zircon3D online account. This account is used for license management. Normally, the add-on performs a quick online license verification. Offline Activation If your system does not have internet access, Zircon3D can still be activated. You can generate a manual license token from the Zircon3D website and paste it into the add-on to activate your license. This allows Zircon3D to continue operating in restricted or offline environments. Optional Cloud Backup for Floorplans Zircon3D also provides an optional cloud backup for your floorplan projects. If enabled, your floorplan design can be uploaded to the cloud, which helps prevent data loss if you reinstall Home Assistant or move to another system. Important to note: Only floorplan project data is stored in the cloud Sensor data and Home Assistant data are never uploaded Visualization still reads live data directly from Home Assistant You can learn more about local vs cloud mode in this article: https://forum.zircon3d.com/topic/9/explained-zircon3d-local-vs-cloud-mode Summary 3D rendering and visualization run locally Data comes directly from Home Assistant Your monitoring data stays inside Home Assistant A Zircon3D account is required for licensing Offline activation is supported Optional cloud backup for floorplan projects This design keeps Zircon3D aligned with the local-first philosophy of the Home Assistant ecosystem while still providing optional convenience features.

We’re excited to announce Zircon3D v2.1, bringing several usability improvements, better visualization controls, and refinements based on user feedback. This update focuses on improving the experience on mobile devices, heatmap visualization, and floorplan editing precision. Below are the highlights of this release. ou can also check out the video overview of this release here: https://youtu.be/3_3LnBEamoQ 3D View Control Buttons (Mobile & Tablet Friendly) To improve usability on touch devices, we added on-screen control buttons for common camera actions: Rotate view Pan the scene Zoom in/out These controls make it much easier to navigate the 3D scene on tablets and phones, especially for wall-mounted dashboards or touchscreen environments. [image: 1773259455149-cff316b0-19f7-40fb-adae-3d6de016e816-image.png] Data Card Display & Heatmap Overlay Improvements We improved how data cards interact with heatmaps and added new display controls to reduce visual clutter when monitoring your building, including: Better readability when heatmaps are active Reduced overlapping between heatmaps and data panels Cleaner visualization in environments with many sensors These improvements make the heatmap view clearer and easier to interpret, especially in complex buildings with dense sensor deployments. [image: 1773327570807-f42d4a1e-1a7e-40a6-bd0f-0a9ce81aec46-image.png] Card Display Modes Three modes are available: Detailed – Show all sensor data panels (current behavior). Compact – Only show data panels related to the currently selected heatmap value. Hidden – Hide all floating data panels for a clean heatmap visualization. This makes it easier to focus on specific environmental metrics without unrelated sensors cluttering the view. Additional Display Options Two new options provide further control over what appears in the 3D scene: Show Action Cards – Toggle the display of interactive device cards such as switches or cameras. These appear as small icon bubbles in the scene. Enable Occlusion – Prevent data panels and action icons from rendering through floors. Elements hidden behind floors will now remain hidden, improving visual realism in multi-floor buildings. [image: 1773259779610-404d8b17-a290-4d10-a928-ffbbae75c935-image.png] Sensor Icons for Better International Usability Zircon3D now supports automatic sensor icons for common values such as: Temperature Humidity These icons appear in the data panel, making sensor types easier to identify even when entity names are not in English. [image: 1773328247950-921fb6e7-cbf8-4a92-a019-f3aafe005e22-image.png] Disable Wall/Room Auto-Attach Helper by Holding Shift When editing floorplans, Zircon3D normally uses an auto-attach helper to snap walls and objects together. For more precise editing, you can now: Hold the Shift key to resize rooms freely without auto-attach helper. This allows finer control when adjusting room shapes or sizes. Preview Button for Quick Viewing A new Preview button has been added to the top toolbar. This allows you to instantly preview your building visualization without manually switching to another view tab. You can quickly check how your floorplan and devices appear in the final scene while editing. This makes the workflow faster when designing your building, letting you switch between editing and viewing at any time with a single click. [image: 1773327687088-5c145f3d-02b4-4c0a-8bd5-0aa2499a2f4b-image.png] Automatic Switching Between Editing Modes Zircon3D now automatically switches between Building Edit Mode and Object Edit Mode based on the element you select in the scene. Building Edit Mode – for editing structural elements such as walls and rooms. Object Edit Mode – for editing objects such as furniture, doors, windows, and devices. This removes the need to manually change editing modes and makes the editing workflow more intuitive when building your home or facility model. Bug Fixes & Performance Improvements As always, this release also includes: Various bug fixes Performance improvements General stability enhancements Feedback Welcome Many of these improvements were inspired by community feedback. If you have suggestions or feature ideas, feel free to share them in the forum.

@lina-sayeb Hi, At the moment, Zircon3D doesn’t support importing external 3D models (such as .gltf files) yet. For now, you have a couple of options: 1. Use the existing Air Conditioner model You can place the current Air Conditioner object in the scene as a visual placeholder for the heater. 2. Add the real device from Home Assistant If the heater is a device in Home Assistant, you can: Open the Monitoring tab Find your heater / temperature entity Drag and drop it onto the floorplan It will be placed in the scene as a sensor, and you’ll still be able to see all the monitoring data associated with it. We know that allowing users to add custom objects is a useful feature, and it’s something we plan to improve in the future. If you have any other questions while working on your project, feel free to ask, happy to help!

Home Assistant is widely known as a powerful platform for smart homes. But in practice, many people also use it to monitor small businesses, workshops, farms, greenhouses, and commercial spaces. As sensor networks grow and buildings become more complex, traditional dashboards often become cluttered and difficult to interpret. Zircon3D was designed to solve this problem by adding a digital twin layer on top of Home Assistant, by turning raw sensor data into an interactive 3D representation of your physical space. This approach makes it easier to monitor environments, identify patterns, and manage devices across an entire facility. From Smart Home Dashboard to Digital Twin Most Home Assistant dashboards list devices as cards or charts. This works well for a handful of sensors, but it becomes challenging when a building contains dozens or hundreds of devices. Zircon3D introduces a 3D facility view where sensors, equipment, and spaces are mapped directly into a building model. Instead of scrolling through lists, users can visually explore their environment and immediately understand what is happening in each location. For example: Temperature sensors appear where they are physically installed Machines or appliances can be mapped to specific areas Environmental patterns become visible across rooms or zones This spatial approach helps transform Home Assistant from a device dashboard into a visual monitoring system. Business-Specific Capabilities Multi-Building and Multi-Floor Monitoring Small businesses often operate in spaces that include multiple floors or separate buildings. Zircon3D projects can organize these layouts into a single visual environment. This allows users to monitor sensors across: different floors multiple buildings separate operational areas All within one unified view. Facility Monitoring and Equipment Mapping Zircon3D makes it possible to associate sensors with the physical equipment or spaces they represent. Common monitoring scenarios include: Energy consumption across rooms or machines Air quality monitoring in offices or labs Temperature tracking in storage rooms or server racks Environmental monitoring for plants or food storage Instead of reading numbers in isolation, users can immediately see where the issue occurs in the building. Thermal and Heatmap Analytics One of Zircon3D’s most powerful features is the real-time heatmap system. Heatmaps transform sensor data into a color-based visualization that reveals environmental patterns across a space. This is especially useful for: greenhouses monitoring temperature or humidity distribution server rooms detecting heat concentration warehouses checking environmental uniformity offices analyzing comfort conditions Users can also replay historical heatmaps to review how conditions changed throughout the day. Performance on Home Assistant Hardware Zircon3D uses a GPU-accelerated WebGL rendering engine, allowing complex 3D scenes to run smoothly inside a browser. Even installations running on modest hardware, such as a Home Assistant OS system or small server can display interactive environments with large numbers of sensors. The goal is to provide professional-level visualization without requiring enterprise-grade infrastructure. Data Privacy and Local Control For many small businesses, data privacy and operational security are essential. Zircon3D runs entirely inside Home Assistant as a local add-on, which means: sensor data never leaves the local system building models remain private monitoring operates even without internet connectivity This local-first design ensures that sensitive operational data stays under the user’s control. Scalable Plans for Growing Systems Zircon3D offers a free plan for smaller installations and personal projects. As deployments grow, paid tiers provide higher limits for: project size building areas number of monitored entities This allows users to start small and scale the system as their business expands. More details can be found here: https://zircon3d.com/pricing Simplifying Complex Facilities Large monitoring systems often overwhelm users with data. Zircon3D includes different view modes that help simplify complex environments. For example: Transparent Mode makes walls semi-transparent to reveal sensors behind them Whiteout Mode highlights devices and monitoring data while reducing visual distractions These modes allow managers to quickly locate devices and understand the state of a facility. A Practical Alternative to Enterprise Systems Enterprise facility-management platforms often require expensive hardware, specialized software, and complex deployment processes. Zircon3D offers a lightweight alternative by building on top of the Home Assistant ecosystem: no specialized infrastructure required simple deployment as a Home Assistant add-on flexible enough for both individuals and businesses For many small organizations, this makes advanced monitoring capabilities accessible without enterprise-level costs.

Hi Mitchell, We don’t have this capability at the moment, but what you’re suggesting is a great idea. Allowing users to add simple 3D primitives (like cubes or basic shapes) to block off areas and attach labels would be very useful in many scenarios. It also aligns well with Zircon3D’s visual philosophy, we intentionally favor simpler, abstract representations to keep data visualization clean and readable, rather than relying on detailed or decorative models. This is something we’ve now added to our roadmap, and we do plan to implement it in a future update. Thanks a lot for taking the time to share the idea, feedback like this really helps shape where the product goes.

What happens to my projects if my subscription ends? Short answer: Your projects will NOT disappear. Your data stays safe. Your account will be downgraded to the Free plan, with some limits. After your subscription ends, you’ll be on the Free plan, which includes: 1 editable project Up to 1000 m² building area Up to 25 monitored devices Heatmap view: Temperature (Free plan feature) *This quota is based on the Free plan limits as of January 2026. What if I have more than the Free plan allows? You can still view everything, but editing is limited: Multiple projects You can view all projects You can edit only one project at a time You decide which project to keep editable If it’s not the one you want: Go to Project → More > → Project Settings Delete it The next project becomes editable This lets you choose which project fits the Free plan Area / devices / features over quota Projects that exceed Free limits will show warnings (like in the screenshots) You can: View everything Remove devices, reduce area, or simplify the project Once it fits the Free plan limits, it works normally again Important takeaway ️ No lock-out ️ No data loss ️ No forced deletion ️ You’re always in control of what to keep If you later re-subscribe, all advanced features and higher limits are instantly available again. Example after downgrade In this screenshot, the project “test” is the active project and can be viewed, edited, and deleted. All other projects are automatically switched to view-only mode. They remain fully visible, but editing is disabled until you delete projects or adjust your setup to meet the Free plan quota. [image: 1769699739170-9a9a7df4-6f11-45ba-b8ed-a168eee0994f-downgrade-1.png] View-only projects can be opened and viewed, but not edited; they can still be deleted from Project Settings → Advanced.

@keiflab Glad to hear it’s working after the update, thanks for letting us know!

Hi David, This is unfortunately a known issue related to a Home Assistant API called ingress, which allows our add-on’s UI to communicate with its backend. It appears that the ingress channel is only fully activated after the add-on UI has been opened at least once from Home Assistant. If the UI is accessed via a web card before that initial opening, Home Assistant may raise this error. Workaround As a workaround, our add-on also exposes port 11200, which bypasses Home Assistant’s ingress proxy entirely. For example, instead of using this URL: http://homeassistant.local:8123/api/hassio_ingress/ym-tlrzEEeGSTSNCz7up0Gf3uqHboBU5NGFvBfH7AMY/offline/viewer/?group=haEBrqFXAEIs&project=sLVclZKQrCvP#cam&p=0.00,0.00,0.00&h=40.11&v=39.56&z=400.00|dsp&fs=1.00&fd=tc&wc=1.00&wd=t&od=tc&thm=auto|viz&layer=rkqaX00R You can replace: :8123/api/hassio_ingress/ym-tlrzEEeGSTSNCz7up0Gf3uqHboBU5NGFvBfH7AMY with: :11200 So it becomes: http://homeassistant.local:11200/offline/viewer/?group=haEBrqFXAEIs&project=sLVclZKQrCvP#cam&p=0.00,0.00,0.00&h=40.11&v=39.56&z=400.00|dsp&fs=1.00&fd=tc&wc=1.00&wd=t&od=tc&thm=auto|viz&layer=rkqaX00R Additional notes Home Assistant ingress has caused several issues beyond this one—some users have also reported unstable connections. Accessing Zircon3D directly through port 11200 is generally more stable and can help avoid these ingress-related problems. It’s possible that the Home Assistant team will improve the ingress proxy in the future. Until then, this is currently the most reliable workaround. Please give this a try and let us know if it works for you. Thanks in advance, Chris

Design decisions, technology choices, and what to expect on mobile and tablets Zircon3D is often described as “fast” or “smooth,” but that performance is not accidental. It is the result of deliberate architectural and technical choices made from the very beginning of the project. This article explains why Zircon3D performs the way it does, what technologies make it possible, and why certain interactions especially on phones and tablets are currently more limited, even though the core system itself remains highly performant. A real-time system, not a rendering pipeline Many traditional 3D tools follow a render-first workflow: Design → export → render → view Any change requires reprocessing the entire scene Zircon3D follows a different approach. It is built as a real-time visualization engine, where: The 3D scene is always live Data changes update the scene incrementally There is no export or re-render cycle This is a fundamental reason why interactions feel immediate and responsive. GPU-accelerated rendering with WebGL At its core, Zircon3D runs on a GPU-accelerated WebGL rendering pipeline, which means: Heavy visual work is handled by the graphics card, not the CPU Large scenes remain interactive even with live data updates Animations, lighting, and heatmaps are computed efficiently Rather than relying on pre-rendered images or static textures, Zircon3D renders geometry and visual states dynamically, frame by frame. This is what allows: Smooth camera movement Real-time device state changes Continuous heatmap updates without freezing the UI Data-oriented scene design Zircon3D does not treat the 3D view as a decorative layer. The scene is directly driven by structured data, including: Rooms and spaces Devices and sensors Live state updates from Home Assistant Only the parts of the scene that actually change are updated. This avoids unnecessary recalculation and keeps performance predictable, even as systems grow. Separation of interaction logic and rendering Another key performance factor is architectural separation: Rendering logic is isolated from UI logic State updates are carefully scoped Expensive operations are minimized during interaction This makes actions like: Dragging objects Rotating the view Zooming in and out feel smooth and consistent, even on modest hardware. Why mobile and tablet interactions are currently more limited Zircon3D’s core engine performs well on phones and tablets. However, interaction is a separate challenge from rendering performance. On desktop: Mouse and keyboard provide precise control Complex gestures are easy to distinguish On mobile and tablets: Fingers are less precise Gestures overlap (drag vs pan vs rotate) Screen space is limited Accidental input is more likely Rather than shipping a compromised or frustrating editing experience, Zircon3D currently focuses mobile and tablet usage on: Viewing Monitoring Light interaction This is a deliberate design choice, not a technical limitation of the engine itself. Roadmap: hand-friendly interaction on tablets Tablet-first interaction requires different design thinking. Zircon3D’s roadmap includes: Larger, touch-optimized interaction zones Gesture-aware tools designed specifically for fingers Reduced precision requirements for placement and control Editing modes tailored for tablet usage rather than adapted from desktop This work is planned as a dedicated tablet experience, not a scaled-down desktop UI. High performance as a long-term commitment Performance in Zircon3D is not a one-time optimization. It is a guiding principle that affects: Rendering architecture Data flow design UI structure Feature decisions This is why Zircon3D can: Scale from small homes to complex environments Handle real-time data without freezing Remain responsive even as features grow In summary Zircon3D is high-performance because it is: A real-time system, not a static renderer GPU-accelerated by design Data-driven at its core Architected to minimize unnecessary work While editing on phones and tablets is currently limited by interaction constraints, the underlying engine is already capable and a tablet-friendly, hand-first experience is actively planned. Zircon3D is built not just to look good today, but to remain fast, reliable, and scalable as your system grows.

Which 3D Floorplan Tool Is Right for Home Assistant? https://youtu.be/DmW2T6G2TiU For years, many Home Assistant users relied on tools like Sweet Home 3D or traditional CAD software, powerful for drawing, but limited to static images that quickly fall out of sync with a live smart home. In 2026, the game has changed. This article compares Zircon3D with Sweet Home 3D and other popular floor-planning tools, and explains why Zircon3D was designed from the ground up for real-time visualization with Home Assistant. Sweet Home 3D - The “Static Hobbyist” Choice The workflow You design your house, render a nice image, then manually place invisible buttons or overlays in Home Assistant. The problem Even the smallest change, such as moving a lamp or adjusting a wall, requires re-rendering the entire scene from scratch. Simple layout tweaks can easily cost 20–30 minutes, turning quick experiments into a slow, frustrating workflow. What you end up with is a static picture of your home, not a live model that can evolve with your smart system. Your smart home evolves daily, but your floorplan stays frozen in time. Zircon3D advantage: Live interactivity Zircon3D uses a real-time WebGL engine. There’s no exporting and no re-rendering. Move a light, rename a room, or add a sensor and every connected dashboard updates instantly. Your home becomes a living model, not a snapshot. Floorplanner - The “Cloud Designer” The workflow A polished web-based tool with a large furniture library, excellent for interior design and real-estate mockups. The problem Floorplanner isn’t built for smart homes: There is no native integration with Home Assistant, making it difficult to connect real devices or automation data to the floorplan. Displaying live sensor values typically relies on screenshots, manual updates, or hacky workarounds that quickly become outdated. The tool has no concept of device state or animation, so lights, fans, and other devices can’t visually reflect their real-time behavior. It’s a design canvas, not a monitoring system. Zircon3D advantage: IoT-first DNA Zircon3D was designed from day one to work with Home Assistant. That’s why features like: Thermal heatmaps Real-time device state animation (fans spin, lights glow, heaters pulse) Room-aware dashboards are native concepts—not afterthoughts. Matterport - The “High-End Pro” The workflow Scan your house using a dedicated 360° camera and upload everything to a professional cloud service. The problem The overall cost is high, combining specialized scanning hardware with an ongoing subscription fee that can be hard to justify for home or small setups. All scans and models are stored and processed on external servers, meaning you don’t have direct control over where your data lives or how it’s handled. For many Home Assistant users, mandatory cloud storage and processing raise privacy concerns and become a deciding factor against adoption. It looks impressive, but comes with tradeoffs. Zircon3D advantage: Local-first privacy Zircon3D delivers a professional 3D experience without forcing your home data into the cloud. Your floorplan and sensor data stay inside your network, while still offering smooth visuals and real-time interaction. Other tools you might consider (and why they fall short) SketchUp - Powerful, but manual, static, and not automation-aware Planner 5D - Beautiful visuals, but no smart-home integration Traditional CAD tools - Accurate, but completely disconnected from live data All are great at drawing. None are great at living with your home. Why Zircon3D is different Zircon3D isn’t just a 3D floorplan tool, it’s a visualization layer for Home Assistant. Real-time 3D (not exported images) Native Home Assistant integration Heatmaps, dashboards, and device animations Local-first by default, cloud-optional Designed for monitoring, not staging If you want your floorplan to reflect what your home is doing right now, Zircon3D is built for that job. Zircon3D - The “Home Assistant–Native” Choice Zircon3D is a 3D visualization system designed specifically for Home Assistant, focusing on real-time interaction rather than static rendering. It offers a free account to get started, with affordable paid plans that are significantly lower than professional scanning or other design tools, making it practical for both home users and small facilities. Unlike traditional floor-planning apps, Zircon3D runs as a live WebGL engine, allowing layouts, devices, and sensor data to update instantly without re-exporting or re-rendering. It supports features like room-aware dashboards, heatmaps, and device state visualization, all while keeping performance smooth on everyday hardware. Most importantly for many Home Assistant users, Zircon3D follows a local-first design by default, keeping your floorplan and sensor data within your own environment, with cloud features remaining optional rather than mandatory.

If your goal is understanding, monitoring, and interacting with your smart home in real time, Zircon3D stands in a category of its own. Your home isn’t static anymore. Your floorplan shouldn’t be either.
