MiBoxer MLZ5 firmware 1.3.0: Lights turn on by themselves with Apple Adaptive Lighting

Hi,

I have an issue with six MiBoxer MLZ5 controllers using Apple Adaptive Lighting. All six are running firmware 1.3.0 and are connected to Apple Home via Matter over Thread. An Apple TV 4k is acting as the home hub and Thread border router.

Three controllers are set to RGB+CCT mode and three to CCT mode. Apple Home offers Adaptive Lighting for all of them and all six show the same problem.

With Adaptive Lighting enabled, I can switch a light off in Apple Home and the LED strip turns off normally. At some point later, the strip turns on again by itself. Apple Home still shows the MLZ5 as off, even though the LEDs are physically on.

This has happened repeatedly, both during the day and at night. The controllers are installed in two different rooms, and the issue occurs in both CCT and RGB+CCT mode. There are no automations or scenes set up in Apple Home. DND is enabled on all six controllers.

When Adaptive Lighting is disabled, the problem does not appear. However, disabling this feature is not a viable solution for me.

For comparison, I tested a Matter over Thread CCT controller from another manufacturer in the same Apple Home and Thread setup. This has worked reliably over several days with Adaptive Lighting enabled. The LEDs stayed off and used the correct adaptive color temperature when I switched them on manually.

It this a known issue with the MLZ5 and is a fix planned? Is firmware 1.3.0 the latest version? Can existing controllers receive firmware updates through Matter OTA in Apple Home to address this issue?
