@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

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.

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: 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.

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.
