The Importance of 3D Visualization in Smart Home Applications
Smart home technology has revolutionized the way we interact with our living spaces. From controlling lighting and climate to monitoring security, smart devices offer an unprecedented level of convenience and automation. However, as the number of connected devices in a home increases, managing them effectively becomes a challenge. This is where 3D visualization comes into play, offering an intuitive, interactive, and spatially accurate way to monitor and control smart homes.
Traditional smart home dashboards often rely on lists, maps, or static 2D floor plans. While functional, these interfaces can be limiting when dealing with complex setups. A 3D visualization-based system enhances user experience in several ways:
A 3D floor plan takes smart home management to the next level by offering a visually intuitive way to interact with devices. Instead of reading through a list of sensors or scrolling through a 2D map, users can simply navigate a realistic digital twin of their home, selecting and adjusting devices in real time.
Among the available smart home visualization solutions, Zircon3D stands out as a unique and powerful system designed specifically to integrate with smart devices.
As smart home ecosystems grow more complex, 3D visualization will become an essential tool for homeowners and facility managers. By providing an intuitive, interactive, and visually engaging experience, Zircon3D bridges the gap between technology and usability, making smart home control accessible for everyone.
If you're looking to enhance the way you interact with your smart home, Zircon3D offers the perfect solution—a powerful, scalable, and user-friendly 3D visualization platform designed for the future of smart living.

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.
️ Why a 3D Heatmap is Better Than NumbersMost 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:
Color-coded layers mapped directly onto your 3D space make it obvious what’s happening in your home — no charts or tables required.
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 MoreZircon3D 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.

When adding your monitored devices to the floorplan, you can:
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"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.
5. Floor Material Customization (Pro Users Only)
Pro users can now customize floor materials for each space.
To change a floor’s material:
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.
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.
Our core mission is to provide powerful visualizations, not to collect or store user data. That's why:
When you create a project in Zircon3D, you can enable the Local-Only toggle. Here's what happens:
If you're offline or prefer to stay fully local:
That's it. No internet connection is needed after activation.
If you leave Local-Only unchecked (the default option), here's how it works:
| 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 |
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.
In this tutorial, we’ll walk you through the process of creating a floorplan in Zircon3D step by step.
Start by adding a building, giving it a name, and adjusting its size using the middle mouse scroll.
Add rooms using the Building Parts panel by dragging and dropping room templates. Resize them by adjusting the blue dots at the corners or dragging the edges.
Customize walls by setting the Exterior Border and Interior Border to define walls. For open spaces like a front porch, set the exterior wall to None.
Create an open area by adding a regular room and setting Fill to None in the Property panel to remove the floor.
Place doors and windows by selecting them from the Building Parts panel and positioning them as needed.
If a roof wasn’t set during building creation, add one by clicking the plus button to create a new floor, setting the Floor Type to Roof, and positioning it above your highest floor. For multi-floor buildings, place additional roof sections where needed and adjust the gable height for sloped roofs.
Adjust the view by modifying floor separation, wall height, and display settings. Switch between true color and transparent modes to customize your view. These settings won’t affect the saved floorplan.
Once complete, explore different layouts and fine-tune your design in Zircon3D.
In this video, I’ll show you how to add Zircon3D as a dashboard card in Home Assistant using the Sectional Dashboard. You’ll learn how to:
Open a Zircon3D project and adjust the viewer settings
Copy the viewer URL and add it as a Webpage card in Home Assistant
Customize the floorplan view, including top-down mode, themes, and heatmaps
Control smart devices directly from the dashboard
This method allows you to integrate real-time 3D visualization with Home Assistant for a more interactive and dynamic smart home setup.
