Hi everyone! Zircon3D v1.2 is now live.
This release introduces several new features, including customizable stairs, wall openings, and standalone divider walls. We’ve also added support for wall-mounted items like lights and framed pictures, as well as ceiling-mounted lights. On the Home Assistant side, the enhanced Monitoring panel now supports template sensors with a configured unique_id, KNX integrated entities and other standalone entities from Home Assistant, along with improved search and filter capabilities. Pro users can now change floor materials, and as always, we’ve included various bug fixes and improvements.
1. How to Add Customizable Stairs
You can now add fully customizable stairs under Building Parts, with support for straight, L-shaped, and U-shaped designs.
To customize a stair:
Select the stair and open the Properties Panel on the right.
Enable the Override toggle to unlock advanced settings.
Adjust the Width, Tread Depth, Riser Height, and the overall Rise and Run.
For L-shaped stairs, toggle between Left and Right turns.
U-shaped stairs also support Left and Right configurations.
This gives you flexible control to design the staircase that fits your layout perfectly.

2. How to Add Divider Walls and Wall Openings
To add a standalone divider or create an opening in a wall, go to the Building Parts tab and open the Rooms sub-tab.
Divider Walls:
Drag and drop a Divider onto the floorplan to create a separate wall. You can resize, reposition, and rotate it using the position helper to match your preferred layout.
Wall Openings:
Drag and drop the Opening component onto any existing wall. This creates an opening within the wall, which you can resize by dragging the blue handles. To remove the opening, select the parent room and use the right-side Properties Panel.
These tools offer more flexibility for refining your floorplan structure.
3. Wall-Mounted and Ceiling-Mounted Items
You can now easily mount objects directly to walls and ceilings:
Ceiling Lights:
Select a ceiling light and drag it over your floorplan. When you hover near a ceiling, it will highlight, drop the light to mount it in place.
Wall-Mounted Items:
Wall-mounted lights and framed pictures can be dragged onto any wall. The system will automatically align and attach them to the wall surface.
This makes it simple to add decorative or functional elements directly onto your structure.

4. Enhanced Monitoring Panel with Search & Filter, Supporting Template and KNX
This update brings expanded compatibility to Zircon3D’s Monitoring panel. We now support Template Sensors (with unique_id), KNX integrated entities, and other standalone entities from Home Assistant.
When adding your monitored devices to the floorplan, you can:
Drag and drop the Home Assistant Entities or devices from the Monitoring Panel directly onto the floor, or
Map them to furniture models for a more immersive experience.
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"
A valid 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:
Select the floor from the Navigation Tree on the left.
Then, choose a material from the Properties Panel on the right.
This allows greater control over the look and feel of each room in your 3D model.
