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

Tami Liu

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.

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.

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.

We’re excited to introduce Zircon3D v2.2, a feature-rich update focused on making 3D building visualization more flexible, interactive, and useful for real-world smart home and facility scenarios.

Watch the v2.2 release video here:

This release adds support for custom GLB models, editable simple cube objects, more smart device control cards, room-level Box View styling, multiple selection, and many bug fixes and performance improvements.

Custom Models: Upload Your Own `.glb` Models

You can now import your own .glb 3D models into Zircon3D.

This makes it possible to add custom furniture, equipment, machines, facility assets, or any other 3D model that better represents your real space.

This is especially useful when the built-in model library is not enough for your specific project.

Simple Cube Object

We added a new Simple Cube Object.

This object is very flexible: you can edit its:

Width
Depth
Height
Color or material

Even though it starts as a simple cube/block, it can be resized into many useful forms, such as a table, platform, partition, box, equipment block, parking area, raised base, or simple placeholder object.

It is a small feature, but very practical for quickly building custom scenes.

More Smart Device Control Cards

Zircon3D v2.2 adds more interactive control cards for Home Assistant entities.

The enhanced control cards include:

Light Card - Supports brightness percentage and color control.

Cover Card - For garage doors, windows, shades, blinds, curtains, and other cover entities.

Climate Card - For air conditioners, heat pumps, thermostats, and similar climate devices.

Lock Card - For door locks and other lock entities.

Fan Card - For fan entities, with related controls.

These cards make Zircon3D not only a 3D visualization interface, but also a more convenient 3D control layer for your smart home.

Status Bubbles on the Floorplan
Control cards also show clear colored status bubbles directly on the floorplan. This makes important states much easier to notice at a glance, such as when a window is open, a garage door is open, or a door is unlocked.

This provides a more intuitive way to understand the real status of your home or building directly from the 3D view.

Room Box View

We added Box View support at the room level.

You can now show rooms as colored box-style blocks and assign colors to different rooms. This provides a cleaner and more abstract way to understand room layout, zones, or functional areas.

In the next version, we plan to extend this feature so the room Box View can be mapped to monitoring sensor data, allowing rooms to be colored dynamically based on real-time values. For example room occupancy or other sensor data.

Multiple Selection

You can now select multiple objects or rooms by holding the Ctrl key.

This allows you to move or delete multiple items at once, making editing much faster and more convenient when working with larger floorplans.

Bug Fixes and Performance Improvements

This release also includes many bug fixes and performance improvements across the Designer and Viewer.

We continue to improve stability, usability, and the overall editing experience as Zircon3D grows into a more powerful 3D visualization platform.

This usually happens due to a Home Assistant ingress authorization issue.

Related: https://forum.zircon3d.com/topic/6/

How to fix it

You have two options:

Option 1 (Recommended)
Use port :11200 to access Zircon3D directly.

Open Zircon3D via http://<your-ha-ip>:11200
Copy and use the view link from there
This avoids the ingress issue entirely

Option 2 (Using default HA port 8123)
If you’re accessing through port 8123, you need to authorize Zircon3D first:

Open Home Assistant
Click the Zircon3D tab in the left sidebar
Then reload your dashboard/view

Why this happens

Home Assistant only initializes ingress access after the add-on UI is opened once. If you try to load an embedded Zircon3D view before that, it may return a 401 Unauthorized error.

If the issue persists, feel free to reach out with details about your setup

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.

Beyond Temperature Delta

You can apply this method to:

Greenhouse climate (VPD, humidity)
Energy usage per zone
Occupancy and utilization
Air quality metrics

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

@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

Tami Liu

@haoxian2023 Glad it is working now! Good job!
