To understand what you see in the logs, understand ‘autoupdate’.
You can change the behaviour by disabling autoupdate.
You haven’t described the physical response at your device, but guessing that it resumes a previously-set brightness when you command it ON - many people would see that as desirable behaviour.
(This is very device dependent, not all bindings do it that way)
Is this a problem for ypou, or just a puzzle over the logging?
