“I compiled and downloaded the light example to the development board. After setting the brightness to 50% and turning off the light, the brightness automatically changes to 100% when the light is turned on again after a few seconds.”

I (83304) esp_matter_attribute: ********** W : Endpoint 0x0001's Cluster 0x00000008's Attribute 0x00000000 is 254 **********

Every time turning on the light automatically set Cluster id 0x00000008, Attribute id 0x00000000 to 254,How to fix it?

Hello, has this problem been fixed?
I also encountered the same problem. When I turned off the Dimmable through the UI, the brightness on the UI was displayed as 1%, then it immediately became 30%, and the light was also on and did not turn off.

@shaohuayuan @eiSouthBoy This is expected behaviour, please take a look at the this. I have explained why this is happening. It's up to the application how it wants to update the driver on receipt of the On/Off command ( i.e. OnOff or CurrentLevel attribute update callbacks ).
