This page lists the entities of the current CeilSense Mini firmware, grouped by function and radar configuration. The current firmware is a WiFi build for LD2412 + LD2450, so that is the configuration this page describes in full.
Names can change until release. The names on this page come from the current pre-release firmware. Entity IDs in Home Assistant start with your device name, so they can differ per installation.
The Category column shows where Home Assistant lists the entity on the device page: Regular for normal sensors and controls, Config for settings and Diagnostic for technical information. Where several numbered entities work the same way, the table uses N for the number.

With LD2460
The LD2460 build for the Mini is planned for release, so its entity names are not final and are not listed here. Expect target entities with X, Y, distance and angle per target, radar settings and polygon zones. CeilSense V2 shows what this radar offers on that model.
With LD6002B
Firmware for the LD6002B on CeilSense Mini is not finished, so its entity names are not final and are not listed here. Expect presence per target, detection areas, target and point counts, X, Y and Z per target in meters, and settings for installation mode, sensitivity and trigger speed.
Climate
The Mini has no climate sensors and no air pressure sensor, so there are no CO2, temperature, humidity or air pressure entities. For those readings, see CeilSense V2 and CeilSense Pro.
