I have an automation set to switch on the lights at 50% brightness at 7:00 pm. I have a second automation set to turn off the lights at 12:00 am. I want to write another automation to simply reduce the brightness to 25% at 10:00 pm, keeping the lights on. I notice there is an automation choice of "Brightness -" but I cannot find an explanation of what this is. There is no selection option for a level to which to reduce the brightness.  Can someone please help me understand how to write an automation on the Tapo app to keep the lights on but simply reduce the brightness as indicated above?  (It may be just as simple as writing another automation to "Turn On" at a set brightness...and I guess that's ok too.  But if that is the answer, im interested as to what the "Brightness -" and "Brightness +" choices actually do.)
