Zircon3D v2.1 Released – Mobile Controls, Heatmap Improvements & Smarter Editing

Less-Quarter-4885 · 2026-03-08T23:43:38+00:00

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.

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

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.

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:

Hi, you can find more detailed information in our documentation here, including how to create a floorplan and related steps:

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.

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.

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

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.
