Sensor Definitions

Once added to Home Assistant you can configure different settings for your sensor. Below is what each setting does.

Controls

RGB Light

  • One RGB Neopixel LED. Click on the light bulb or color wheel to change the color. Click on the toggle to turn on or off.

Calibrate SCD40 to 420ppm

Sensors

CO2

  • True CO2 reading from the SCD40. This will be Unknown if you do not have the CO2 module. SDC40 can be calibrated following this guide.

ESP Temperature

  • This is the temperature of the internal microcontroller. Think of it like your measured CPU temp on your PC.

DPS310 Pressure

  • Measures the air pressure in the environment.

DPS310 Temperature

  • Measures the ambient air temperature using the DPS310 sensor.

LTR390 Light

  • Light level measured in lux by LTR390.

LTR390 UV Index

  • UV index measured by LTR390.

Radar Detection Distance

  • The last detected distance by the radar. This will stay at the last known value so sometimes can be misleading.

Radar Move Energy

  • The amount of movement measured by the LD2410B. Faster movements have higher percentage.

Radar Moving Target

  • Does the radar have a moving target it is tracking.

Radar Still Distance

  • The last measured distance of a still target. It will hold the last value so sometimes can be misleading.

Radar Still Energy

  • The energy of the current still target.

Radar Still Target

  • Does the radar have a still target.

Radar Target

  • Does the radar have a still or moving target. Good for triggering automation.

Radar Zone 1 Occupancy

  • This is a configurable zone. Think of zones like distances from the radar unit. Zone 1 might be from 0 cm to 100 cm from the sensor. This is telling you if there is someone in that zone. The zones can be defined in the configuration section with “Radar End Zone 1”

Radar Zone 2 Occupancy

  • This is a configurable zone. Think of zones like distances from the radar unit. Zone 2 might be from 100 cm to 200 cm from the sensor. This is telling you if there is someone in that zone. The zones can be defined in the configuration section with “Radar End Zone 2”

Radar Zone 3 Occupancy

  • This is a configurable zone. Think of zones like distances from the radar unit. Zone 3 might be from 200 cm to 300 cm from the sensor. This is telling you if there is someone in that zone. The zones can be defined in the configuration section with “Radar End Zone 3”
Configuration

ESP Reboot

  • Performs a restart of the sensor

Factory Reset Radar

  • Sets the radar's move thresholds back to their original values from the manufacturer

g0-g8 Move & Still Threshold

  • Please refer to the radar tuning guide: Here

ld2410 Bluetooth

  • This allows you to turn on the LD2410's Bluetooth. This allows you to connect to the HLK Radar phone app used for tuning.

Radar Zone 1 Start

  • This sets the starting distance for Zone 1 in cm. This is the distance from the sensor to the start of Zone 1

DPS Temperature Offset

  • Offsets the heat from the ESP chip for a more accurate temperature.

ESP Reboot

  • A control to reboot the ESP32 system.

Factory Reset Radar

  • Resets the radar to its factory settings.

Firmware Update

  • Shows whether a firmware update is available.
Radar End Zones

Radar End Zone 1

  • This defines “Zone 1” of the radar. It is a distance from the sensor that specifies what “Zone 1” is. It connects to the “Radar Zone 1 Occupancy” sensor. So if this number is set to “100” that means from 0 to 100 centimeters from the sensor is zone 1.

Radar End Zone 2

  • This defines “Zone 2” of the radar. It is a distance from the sensor that specifies what “Zone 2” is. It connects to the “Radar Zone 2 Occupancy” sensor. So if this number is set to “200” that means from zone 2 end distance to 200 centimeters from the sensor is zone 2.

Radar End Zone 3

  • It is a distance from the sensor that specifies what “Zone 3” is. It connects to the “Radar Zone 3 Occupancy” sensor. So if this number is set to “300” that means from zone 2 end distance to 300 centimeters from the sensor is zone 3.

Radar Engineering Mode

Radar Timeout

  • Configures the timeout for the radar in seconds.

Startup Light Blink

A toggle to enable or disable the blinking of the RGB LED during MSR-2 initial boot.

Radar Gate Distance Tuning and Timeout
Radar Max Move Distance
  • Maximum distance gate for movement detection. Value between 2 and 8 inclusive
  • Useful in a bathroom or other scenario where you want to avoid detection after a certain gate number (distance).
  • Useful for triggering on "radar target" instead of triggering on zone 1/2/3 occupancy instead.
Radar Max Still Distance
  • Maximum distance gate for still detection. Value between 2 and 8 inclusive. Defaults to 8.
  • Useful in a bathroom or other scenario where you want to avoid detection after a certain gate number (distance).
  • Useful for triggering on "radar target" instead of triggering on zone 1/2/3 occupancy instead.
Radar Timeout

The time in seconds that the radar's presence will stay high after the target is lost.

Radar Gate Configuration

Keeping these enabled permanently is bad

Please toggle ld2410 Bluetooth on, configure your sensor, then turn ld2410 Bluetooth back off. Otherwise, your Wi-Fi and database could become overwhelmed with excessive traffic.
