Xiaomi Gateway 3Partly works LocalWorks on gateway but one user saw lux values differing from cloud

the Light Sensor GZCGQ01LM works with Gateway DMWG03LM Firmware 1.0.6_0016. It reports lux and update is all working. But I notice that the value is off. This is local value it reports from Xiaomi Gateway 3 Integration. This is cloud value it reports from Xiaomi Miot Auto and Mi home app. This is accurate. The shape is good so I downloaded the values and run regressions on both data. It's roughly a nature log curve. Not sure if it's a bug or just me. I tried to delete everything and add them back. It's the same. Technically it still could work with Template conversion.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
