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. [image: 1768240845035-30c5f3a0-a3b5-40af-b901-c102001d96d0-image.png] In short If your goal is interior design or real-estate visuals, the classic tools still work well. 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.

Understanding the environment inside your home has never been more important — and more intuitive — than now. With Zircon3D, you can view real-time temperature and humidity heatmaps across your entire home in a fully interactive 3D floorplan. This feature goes far beyond traditional dashboards. It transforms your sensor data into a thermal layer you can see and feel — at a glance. [image: 1762380296195-72d3f8763a3e5d3afb06dc0f1dde8c16dd1b8fb2.gif] ️ Why a 3D Heatmap is Better Than Numbers Most smart home systems show environmental data as a list of temperature or humidity values per room. While functional, numbers require mental effort — you have to read, compare, and interpret them in context. But with a 3D heatmap, your brain does less work and sees more. The moment you look at your Zircon3D model, you’ll instantly spot: Hot or cold spots Humid zones (like kitchens, basements, or bathrooms) Areas with sensor failure or drop-off Rooms where climate control may be inefficient Color-coded layers mapped directly onto your 3D space make it obvious what’s happening in your home — no charts or tables required. 🧠 Color is a Language Your Brain Understands Humans evolved to read visual cues. A splash of red feels hot. Blue feels cold. We don’t need to "translate" a Celsius value when we see the heat right on the walls or floors of a room. In Zircon3D, each space is shaded based on sensor data pulled in real time from Home Assistant or your supported smart home platform. Whether you're glancing at your bedroom from your phone or exploring your basement from a tablet, the thermal layer gives you a natural, intuitive sense of space and comfort. ️ Built for Home Assistant — and More Zircon3D integrates seamlessly with Home Assistant via our Zircon3D Proxy add-on, letting you visualize all your temperature and humidity sensors automatically in your existing smart home setup. https://youtu.be/YMsyuJpP2RA And we’re not stopping there — Zircon3D is a standalone system as well, with planned support for additional platforms and OEM integrations. Whether you’re a smart home enthusiast or a developer building your own solution, Zircon3D can turn your raw data into an immersive experience. Use Cases Beyond Just Comfort Smart HVAC tuning: See where hot or cold zones exist and adjust vents or thermostats accordingly. Airflow analysis: Identify stagnant or poorly ventilated spaces. Sensor health: Quickly detect dropped or faulty sensors by the absence of data on the heatmap. Energy efficiency: Cross-reference the heatmap with insulation zones or external weather data. Experience It Yourself Your smart home is more than devices — it's a living, breathing environment. Zircon3D’s real-time heatmap feature helps you see it like never before.

Hi everyone! Zircon3D v1.2 is now live. This release introduces several new features, including customizable stairs, wall openings, and standalone divider walls. We’ve also added support for wall-mounted items like lights and framed pictures, as well as ceiling-mounted lights. On the Home Assistant side, the enhanced Monitoring panel now supports template sensors with a configured unique_id, KNX integrated entities and other standalone entities from Home Assistant, along with improved search and filter capabilities. Pro users can now change floor materials, and as always, we’ve included various bug fixes and improvements. 1. How to Add Customizable Stairs You can now add fully customizable stairs under Building Parts, with support for straight, L-shaped, and U-shaped designs. To customize a stair: Select the stair and open the Properties Panel on the right. Enable the Override toggle to unlock advanced settings. Adjust the Width, Tread Depth, Riser Height, and the overall Rise and Run. For L-shaped stairs, toggle between Left and Right turns. U-shaped stairs also support Left and Right configurations. This gives you flexible control to design the staircase that fits your layout perfectly. https://youtu.be/qd_3kGRQCvk 2. How to Add Divider Walls and Wall Openings To add a standalone divider or create an opening in a wall, go to the Building Parts tab and open the Rooms sub-tab. Divider Walls: Drag and drop a Divider onto the floorplan to create a separate wall. You can resize, reposition, and rotate it using the position helper to match your preferred layout. Wall Openings: Drag and drop the Opening component onto any existing wall. This creates an opening within the wall, which you can resize by dragging the blue handles. To remove the opening, select the parent room and use the right-side Properties Panel. These tools offer more flexibility for refining your floorplan structure. 3. Wall-Mounted and Ceiling-Mounted Items You can now easily mount objects directly to walls and ceilings: Ceiling Lights: Select a ceiling light and drag it over your floorplan. When you hover near a ceiling, it will highlight, drop the light to mount it in place. Wall-Mounted Items: Wall-mounted lights and framed pictures can be dragged onto any wall. The system will automatically align and attach them to the wall surface. This makes it simple to add decorative or functional elements directly onto your structure. https://youtu.be/qZKqv394oz0 4. Enhanced Monitoring Panel with Search & Filter, Supporting Template and KNX This update brings expanded compatibility to Zircon3D’s Monitoring panel. We now support Template Sensors (with unique_id), KNX integrated entities, and other standalone entities from Home Assistant. When adding your monitored devices to the floorplan, you can: Drag and drop the Home Assistant Entities or devices from the Monitoring Panel directly onto the floor, or Map them to furniture models for a more immersive experience. These features help you build a smarter, more visual representation of your environment. If the sensor represents a temperature value, make sure to also specify: device_class: "temperature" A valid unit_of_measurement (e.g., "°C") Here’s an example configuration: template: - sensor: - name: "temperature_difference" unique_id: "temp_diff" state: > {% set t1 = states('sensor.aqara_temp_humidity_sensor_temperature_2') | float(0) %} {% set t2 = states('sensor.aqara_temp_humidity_sensor_temperature') | float(0) %} {{ (t1 - t2) | round(2) }} unit_of_measurement: "°C" device_class: "temperature" This will allow Zircon3D to recognize and display the template sensor correctly. https://youtu.be/2vl8UVddpx8 5. Floor Material Customization (Pro Users Only) Pro users can now customize floor materials for each space. To change a floor’s material: Select the floor from the Navigation Tree on the left. Then, choose a material from the Properties Panel on the right. This allows greater control over the look and feel of each room in your 3D model.

Own Your Data - You Can Choose Between Cloud Convenience and On-Premise Privacy Monitoring data never leaves user's local network You have full control over where your floorplan data is stored, cloud, local, or both All monitoring data (like sensor readings) stays 100% local inside Home Assistant The cloud version does not display or access any sensor/device state This setup lets users decide how much convenience vs. control they want, without compromising privacy or ownership. We’re also exploring more advanced options for self-hosting everything , including full 3D rendering on local devices or private servers. [image: 1762454434362-472170916_122204971070210827_877832266592100984_n.jpg]

Zircon3D is designed with privacy, flexibility, and resilience in mind. Whether you're running the Home Assistant Add-on or the standalone Docker version, we offer two distinct modes of operation for storing your floorplan data: Local-Only and Cloud-Synced. Why We Built It This Way Our core mission is to provide powerful visualizations, not to collect or store user data. That's why: All sensor and device data stays local at all times. We give you full control over how your floorplan data is stored. You can run Zircon3D entirely offline, including 3D rendering and modeling. Local-Only Mode (Fully Offline) When you create a project in Zircon3D, you can enable the Local-Only toggle. Here's what happens: Your floorplan data is saved only inside Home Assistant. The Zircon3D application are bundled inside the add-on or Docker package. There is no dependency on the cloud. License Activation in Local-Only Mode If you're offline or prefer to stay fully local: Log into your Zircon3D account on our website. Choose your plan or update it. Generate a License Access Token. Paste the token into the add-on settings in HA. That's it. No internet connection is needed after activation. Cloud-Synced Mode (Default) If you leave Local-Only unchecked (the default option), here's how it works: Your floorplan data is saved both locally and in the cloud. This provides an automatic backup. If you reinstall or lose your HA setup, you can easily pull your project from the cloud to restore it. Still: No sensor or device data is sent to the cloud. Ever. What We Store (and What We Don't) Type Cloud-Synced Mode Local-Only Mode Floorplan (project data) Saved locally & cloud Saved locally only Sensor/device states Never stored or leave local network Never stored or leave local network License check Automatic Manual token input Supported Platforms Home Assistant Add-on Docker Installation Both versions contain all required assets and are fully functional offline with the Local-Only option. If you have any questions or want help deciding which mode is right for you, feel free to ask in our community forum. Zircon3D puts you in control of your data — as it should be.
