Brightness is lowered automatically some time after manual change

[TheFes]

I have several Tuya lights.
When I change the brightness on them (either in HA, or by voice via Google Home) the brightness is lowered automatically after 5 minutes.

Light status at 10:08 AM, just after manually changing them

Light status at 10:13, all brightness levels are lowered, without any manual intervention

There are no automation in place to set the brightness (only for one of them, but it sets the brightness either to 1 or to 255, not to a level in between), so this can not be the cause.

Sometimes the change can be within a minute, sometimes it can be after 5, but it is changed every time.

Did a check with the normal Tuya integration. Then this behavior is not shown.

But brightness just change in the slider position or also real brightness is changed?

Brightness is actually changed

Sorry, please ignore my comment of 2 days ago. The real brightness is not changed. I thought it was, because the light I used to check this has an automation active which changes the color temperature of the light. So it seemed less bright, but it was only warmer.

So, the brightness value throughout HA is lowered (triggering the automation described above), but the actual brightness of the light is not changed, and remains as is.

Due to this behaviour, I used the normal Tuya integration for a few days, but I'm back to Tuya Custom now. Besides the issue described in this topic, it works a lot better than the normal Tuya integration. So thanks for all your hard work on this!
