Incorrect illuminance readings and missing battery level via matter

[Zen2928]

Hello,
I have a presence sensor that also measures illuminance. The device is paired with HomeKit via a Matter bridge, but I noticed that the brightness values displayed in HomeKit are incorrect. For example,

Tuya app shows 1640 lx, HomeKit 1.04 lx;
Tuya shows 393 lx, HomeKit 1.01 lx;
Tuya shows 164 lx, HomeKit 1 lx.

Is there a way to fix this issue so that HomeKit correctly reflects the illuminance data? Additionally, is it possible to add battery level monitoring for this device in HomeKit?

It's kind of weird, In fact, I saw that the configuration of this device already includes the power report, and the brightness values are also configured, so I did not find anything abnormal.

Perhaps you can try to bridge the device to apple home and compare the difference between the three platforms.

I will not modify the configuration of the device for the time being, waiting for your reply.

Thank you for your response.
I checked how it looks in Home Assistant, and the light intensity value always shows 1 lx. However, the battery percentage is displayed only in Home Assistant.

I’m sending screenshots from Tuya, HomeKit, and Home Assistant.
