I have multiple LIFX bulbs and my automation used to work well to set the Color, Brightness, and the color_temp when they turned on. In the past couple of months they stopped working. I finally got around to troubleshooting them and found that the issue is with the color_temp setting. If I remove this from my configuration they work fine. I have also tried Kelvin and configuring these same settings in the LIFX_Set_State call but that does not work either. Below is some basic code with the color_temp in it which does not work. If you comment out the color_temp it works fine.
For whites add “white_value: 255” under data:
For colors use rgb_color: [X,Y,Z] under data:
Examples of both are below. I’ve commented them out and use an automatic brightness and kelvin change automation based on time of day now.
