So an interesting situation that I first thought was ‘normal operation’ seems to be more an issue/bug I believe - however I am still unsure where the bug is. However I suspect it is in HA or the integration for WLED.
I have my TV lights controlled by an WLED controller - which I have had to limit in WLED the wattage for the lights. Controlling the lights (incl. brightness) via the WLED webpage/controls works fine.
Slide brightness all the way to the left for min. and all the way to the right for max.
However in Lovelace and also using Node Red to control the WLED instance it seems like the scale is MUCH smaller. The Brightness adjustment is more like 0-35% on the slider/node red in HA, while you can go more 36-100% in the slider it doesn’t do anything since you’re already at full brightness.
This obviously makes it difficult to finely adjust in Love Lace for one and skews the numbers in Node Red.
Yesterday I added Hyperion NG - and at first didn’t understand why when my light scene activated the LED’s were almost so dim I couldn’t see them. However I eventually noticed the settings I used when driving the commands from HA to WLED through the integration is skewed and doesn’t work with the WLED module when it gets commanded by the Hyperion NG software.
If I would move the slider in WLED to 100% everything worked as if it was 100%! So I edited my LED call in Node red to send a brightness of 255 to WLED and sure enough that worked!
So the issue is somewhere in HA/WLED integration where the scaling is off from what I can tell.
Hopefully I explained this well enough for someone to understand.
