📢 Zircon3D v2.2 Released! Check Out What’s New!

@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.

This post shares our current development direction after the Zircon3D v2.2 release. Current Focus: Routing System After v2.2, our next development focus will be the routing system. The idea is to make Zircon3D able to visualize connected systems inside or around a building, such as Energy systems, solar panels, home batteries, EV chargers, main panels and inverters, water pipes, sewer lines, greenhouse irrigation systems, HVAC ducting or airflow paths, and other routing-style systems in the future. The goal is to make complex building data easier to understand visually from a 3D layout, showing where things are, how they are connected, and how data or resources flow through the system.

Current: 2026-S2 Routing System - Draw and visualize connected routes such as energy lines, wires, pipes, ducts, or irrigation paths in 3D. Static Floating Card - Display static text, labels, notes, or images above objects in the 3D view. Template System - Create reusable templates for buildings, floors, rooms, or groups of objects. Room Box View with Sensor Data - Allow room colors to represent values such as occupancy, air quality, or other sensor data. Copy and Paste - Clone objects more easily using shortcut keys or pointer-based actions. More Usability Improvements - Continue improving editing workflow, object placement, visual controls, and general usability. Suggest a Feature We’d love to hear your ideas and feedback. If there are features you’d like to see in Zircon3D, please share them in our forum Your suggestions help us understand real use cases and prioritize future improvements. Notes Items listed in this roadmap are directional and not guaranteed commitments. Priorities may change based on technical progress, user feedback, and real-world use cases.

No. Zircon3D is not open source / FOSS. Zircon3D is a commercial product developed by Lichr Inc. We provide a Free plan for general home users, but the main Zircon3D application source code is not open source. What is public? Some installation-related resources are public, such as the Home Assistant add-on repository and setup instructions. These are provided so users can install and run Zircon3D with Home Assistant. You can find the documentation here: https://zircon3d.com/docs What is not open source? The main Zircon3D application source code, including the 3D Designer, Viewer, rendering system, device mapping logic, and related product features, is not open source. Can I use Zircon3D for free? Yes. Zircon3D has a Free plan for home users. Paid Home and Business plans are available for users who need more monitoring devices, advanced visualization features, or larger/commercial use cases. Why is Zircon3D not open source? Zircon3D is built and maintained as a commercial product. Keeping the main application closed-source helps us continue development, provide support, improve the product, and build long-term sustainability. We understand that some users prefer open-source solutions, and we respect that. For users who are comfortable with a commercial product that includes a Free plan, Zircon3D is available to try with Home Assistant.

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?
