VS370-0583 get real illuminance value

Hi,

I am receiving only a value of 0 or 1 for illuminance via MQTT, while in NFC ToolBox the light status is shown as either Bright or Dim.

I tried setting the thresholds to 80 lux for the minimum value and 120 lux for the maximum value, but the sensor still detects the environment as dark indoors, even with the lights switched on. If I move it outside, it correctly detects sunlight.

Am I configuring the settings incorrectly?

Also, is there any way to see the actual numeric illuminance value detected by the sensor directly in ToolBox, rather than only the Bright/Dim status?

Device details:

{"applicationID":1,"devEUI":"xxx","deviceName":"VS370-0583","device_status":1,"firmware_version":"v1.1","gatewayTime":"2026-08-28T22:06:34+02:00","hardware_version":"v1.1","ipso_version":"v0.1","lorawan_class":0,"sn":"xxx","tsl_version":"v1.0"}

Thanks!

Hi Chiara Tecnoelettrica,

Thanks for contacting Milesight-IoT Support Team.

Below are our replies to your questions:

1. Illuminance status value:

"00" -> Dim

"01" -> Bright

2. Logic for determining "Bright" & "Dim" states:

Initial light intensity ≥ maximum value -> Bright

Initial light intensity < maximum value -> Dim

When light intensity shifts from bright to dim, the state switches from bright to dim only when the intensity falls below the minimum value.

When light intensity shifts from dim to bright, the state switches from dim to bright only when the intensity exceeds the maximum value.

3. Actual numeric illuminance value:

We are sorry that VS370 does not support retrieving the actual lux illuminance value. It can only display the status based the set thresholds.

Have a nice day.

Best Regards,
