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

Patch Update: Zircon3D v2.2.1 — 2026-05-15 We released a small patch update for Zircon3D v2.2. New Feature Added Project Tools: support exporting and importing Zircon3D space-plan / floorplan data. Bug Fixes Fixed an issue where switching edit mode did not reset Box View correctly. Fixed behavior issues related to View Settings, Floating Cards, and Sensor Card Display. The new import/export feature can be useful when you need to move, back up, or share a floorplan between Zircon3D projects. How to import/export a floorplan in Zircon3D This feature is only for exporting floorplan data from Zircon3D and importing it back into Zircon3D. It is not for importing files from other design systems. Open Zircon3D in Home Assistant. Select your project, then click Edit to open the Designer. In the bottom-left bar, open Project Tools. Choose Import Project or Export Project. When importing, select the project file exported from Zircon3D. After importing, click Save to keep the imported floorplan, or press Undo to discard the changes.

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.
