Max Brightness setting at 100%
Would be a nice feature if there was a way to control the max brightness or output at 100%. I have some bulbs that I switched to OpenBK from MagicHome and the leds have burnt out as they were way to bright at 100%. They were literally almost twice as bright as stock. A max brightness option would be great especially for these bulbs that have the LED's limited by the original controller. ESPHome has an option for this and I have switched my other bulbs from the BL602's to D1 minis to prevent them from burning out.
Maybe this feature can help? https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/led_gamma_control.md
Do you refer to PWM bulbs?
Yes they are PWM controlled LED's. They use RGB for the colors and have a separate cold white output. The RGB I could control lowering the gamma for each color. RGB colors seem fine however with default settings. This does not seem to affect the separate white channel however and that is what has burnt out for being way too bright. Using home assistant if I tell my assistant to turn lights on full brightness it turns them on to what ever the LED's can draw. There is no limiter for CW or WW only RGB and thats by adjusting Gamma. Unless I am missing something. I also tried using gamma ctrl brightMaxCW or brightMaxWW but these are not valid sub commands. Another guy had a similar issue here and I tried what I could. https://www.elektroda.com/rtvforum/viewtopic.php?p=21487544#21487544
I was able to accomplish what I needed for the most part by using the CTRange 130 250 and limiting it to work with Home Assistant's colors by modifying the color temperature range. Not ideal but it worked. Just have to keep the temp slider off of panels and dashboards so the LED's can't hit max brightness. Also have flags set to 10 and 24 and using channels 1 2 3 and 5. A max brightness setting or limiter per channel would have made this a lot easier though. This is an option in ESPHome so I thing this is a valuable feature to add to Open Bekken. Especially with some of the bulbs having the LED's limited by the controller for heat and temp and safety reasons.
