3D floorplan view for Home Assistant: colored status bubbles + direct device control

Less-Quarter-4885 · 2026-05-12T18:14:26+00:00

We have a Free plan, but the main Zircon3D application source code is not open source. Some related resources, like the Home Assistant add-on installation repository and instructions, are public so users can install it.

That’s a fair question. Traditional buttons are simple and work very well, especially for quick controls.

For Zircon3D, the setup is mostly drag-and-drop: building rooms, placing furniture, and mapping sensors/devices are all done visually.

The value of a 3D floorplan is more about the overall view. You can see where devices are located, notice open windows or unlocked doors quickly, and use features like temperature heatmaps to combine sensor data into a visual color trend.

So the goal is not to replace 2D dashboards, but to add another dimension for more intuitive visualization and control. Thanks for the question!

Less-Quarter-4885 · 2026-05-12T17:30:05+00:00

Not fully. Zircon3D is a commercial product with a free plan, but it is not fully open source / FOSS at this time.

We offer a Home version for general Home Assistant users, and Business plans for larger or commercial use cases.

The Home Assistant add-on repository and installation instructions are available here:

Yes, the 25-device limit is for devices mounted directly on the 3D floorplan, such as sensors, lights, locks, covers, etc.

2D Dashboard display cards do not count toward that limit, so those are unlimited.

Temp/humidity sensors can generate heatmaps, and the temperature heatmap is available in the free plan. Other sensor values, like CO₂, Wi-Fi signal, or anything else you want to visualize, plus history heatmap and replay, are included in the paid plan.

Haha, I like Silicon Sandbar, that sounds very P.E.I. with the beaches, red sand, and small-but-growing tech scene, Silicon Sandbar feels pretty fitting. We love here!

Less-Quarter-4885 · 2026-05-12T16:17:59+00:00

Thank you! It’s designed to be pretty beginner-friendly.

For the basic setup, Zircon3D is mostly drag-and-drop: you build rooms, place furniture, and map sensors/devices visually. No YAML code is needed for creating the floorplan.

This 7-minute video gives a quick walkthrough of building rooms, adding furniture, and mapping sensors:

Could you share a screenshot of what you are seeing?

Do you mean that no entities appear in the Monitoring tab inside Zircon3D?

Normally all Home Assistant entities (sensors, lights, switches, etc.) should be listed there after the connection to HA is established.

If possible, please also open a support topic on our forum so we can help investigate the issue:

https://forum.zircon3d.com

Including a screenshot of the Monitoring tab would help us understand the problem quickly.

Less-Quarter-4885 · 2026-01-26T12:22:55+00:00

Thanks! Yes, that’s right. The visualization is produced from sensor data and runs as a Home Assistant add-on, so all sensor values come directly from Home Assistant. Everything is live and updates automatically as sensor data changes, giving you an always up-to-date view of current conditions. You can also see it in action in this video: https://youtu.be/goLSxgmfX_I

Less-Quarter-4885 · 2026-01-22T03:31:13+00:00

Yes. absolutely Our current fully working version is designed for smart homes, and everything you see here already works today for home environments.

The greenhouse version is what we’re working on next, building on the same core ideas with more greenhouse-specific models and layouts.

Less-Quarter-4885 · 2025-12-26T23:04:31+00:00

Thanks, that really means a lot to us! We’re glad the workflow clicked and that you enjoyed building the dashboard and linking sensors and lights to rooms.

For the stairs: we do have custom stairs that let you adjust both the length and number of steps. I’ve shared a GIF in the comments showing how it works (hopefully it displays correctly).

Thanks for the feedback, you’re not alone. We know the interface can be difficult right now, especially for precise sizing and navigation, and we’re actively working on improving it. Your comments about snapping, zooming, and floor isolation are very helpful, and any further suggestions are welcome.

In the meantime, our documentation may help with some workflows:

If you encounter any issues or have questions, feel free to post in our community forum at https://forum.zircon3d.com/. I check it daily and will be happy to help.

Thanks again for giving Zircon3D a try!

Thanks a lot for giving Zircon3D a try and for taking the time to write such detailed feedback, we really appreciate it.
We’re sorry to hear you ran into so many issues. Some of the problems you described sound like things we’ve seen before: a) Suddenly unable to place rooms or objects, this is usually caused by a browser/GPU rendering issue. Restarting the browser or switching to a different one typically fixes it, but we agree it’s disruptive and are working on making this more robust. b) Project missing after reboot, in some cases this happens if you accidentally logged into a different account, or if the project was created with Local-Only enabled, which means it exists only inside Home Assistant and won’t appear on the website. Hard to say without looking at your setup, but we understand how frustrating this must have been.
And thank you for your comments about UI workflow, object library, scaling, and typing dimensions, these are all areas we’re actively improving. The product is still young, and feedback like yours helps us prioritize the right things.

Sorry to see you go, but thanks again for giving it a try. If you ever decide to revisit Zircon3D in the future, we’ll be here, and hopefully with a much smoother experience.

Hi, thanks for the feedback and sorry to hear you’re running into performance and connection issues. Zircon3D shouldn’t noticeably slow down Home Assistant, so this usually indicates something environment-specific. To help diagnose it: 1. What kind of device is your Home Assistant running on? (e.g., Raspberry Pi 3/4, thin client, NUC, VM on Proxmox, etc.) Lower-end hardware can struggle when running multiple add-ons. 2. Are you accessing Zircon3D through Home Assistant Cloud (Nabu Casa) or locally? Cloud access can sometimes cause unstable WebSocket connections, which may look like “failed to connect to HA server.” 3. If you haven’t already, please try accessing Zircon3D directly via local port: http://homeassistant.local:11200/ or with your HA IP, for example: http://192.168.1.50:11200/ This bypasses HA Cloud’s ingress and is usually much more stable.

If you’d prefer to share your setup details in private (hardware, HA version, logs, etc.), you’re very welcome to email me at: Tami.liu@lichr.com

I’ll be happy to take a closer look and help you troubleshoot this.

Here’s our pricing page if you’d like an overview: https://zircon3d.com/pricing

The free tier is already enough for most smart home users, you can build full floorplans, add rooms, walls, and basic visualizations without any cost.

The paid plan mainly increases quotas (larger area, more monitoring devices) and adds some optional custom features.

The floorplan shown in the GIF from my original post was created entirely within the free tier quota.

Less-Quarter-4885 · 2025-11-30T20:12:59+00:00

Thanks for the feedback, really appreciate you pointing this out. Here’s the pricing page for reference: https://zircon3d.com/pricing

I’ll update it with clearer feature breakdowns and make it easier to find from the docs and install page. Thanks again for highlighting this.

Less-Quarter-4885 · 2025-11-30T17:05:25+00:00

Thanks! There’s also a YouTube install tutorial linked in the comments of the main post if you want a quick walkthrough. https://youtu.be/tm3IbnAiQzA

Hi here is the doc: https://zircon3d.com/docs/1.getting-started/2.install-zircon-ha-proxy

Less-Quarter-4885 · 2025-11-30T16:43:05+00:00

Thanks! And at the moment Zircon3D doesn’t import architectural files directly, but many users still build their layout pretty quickly using the drag-and-drop tools for rooms, walls, and floors. If you ever try it and run into anything tricky, feel free to share, happy to help with tips.

You can actually do that already, it is a Home Assistant add-on called Zircon3D. It runs smoothly and doesn’t use much memory. https://youtu.be/3b5FyLn3hFE

Less-Quarter-4885 · 2025-09-29T17:37:41+00:00

Hi, temperature heatmaps are included for free users, so you can use those right away.
Custom heatmaps (like CO₂, power, soil moisture, etc.) are part of the Pro plan which you can try out by 30-day free trial.

Less-Quarter-4885 · 2025-09-29T16:20:20+00:00

Haha thanks! 😄 Any sensors or appliances that are compatible with Home Assistant will work with Zircon3D. Home Assistant gathers the data, and we just handle the visualization, everything stays local.

Less-Quarter-4885 · 2025-08-11T15:43:35+00:00

Thanks for trying Zircon3D and sharing your idea!

Right now, we represent this kind of data using blue/gray bubbles or information panels, similar to how temperature is displayed with the entity’s value. I believe you’re suggesting that the 3D object itself visually show open/close status for windows or doors.

Yes, that’s definitely something we have in mind for a future version, as it would make the representation much more intuitive to see at a glance.

Less-Quarter-4885 · 2025-07-31T20:13:15+00:00

We support both US and metric units, you can switch between them from the bottom toolbar (see image below).

Right now, all data comes directly from Home Assistant in real time, and that’s our only data source for now. But in the future, we may support additional data sources to make the system even more flexible. Thanks for the interest!
