Explained: How Sensor Data Stays Local in Home Assistant with Zircon3D

[Tami Liu]

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.
