Salutations- been trying to figure out a way to get a LifX RGB light to fade in from 100% white to 20% red over 5 minutes. I have had no luck (obviously) yet. Tried Room Lighting and it just switched to red @ 20% without the transition time
It may not be perfectly smooth because of the difference between white color temp bulbs and a color RGB bult, but try setting your color to something like Hue of 255 and a saturation of 0. Them gradually increase the saturation to its max value.
I was hoping that there was not a limitation using a HE interface to a LifX bulb. It sounds as though there is one. I was really hoping that I was overlooking something in the Rule Machine. Am really going to hate going back to iFTTT....
Try the new Color Animation app to see if it can at least get what you want. With the right timing, plus a rule or other app that starts/stops the "automation" (by way of its activator device) at the desired times, I think it could work, all using built-in options.
Otherwise, Rule Machine does have actions to fade level and/or color temperature over time, but nothing for color. You could certainly create your own rule to do something similar (calculate the difference between the starting and ending hue, saturation, and level, and repeat commands to change them until you get to the ending values -- assuming you can find a "color" that matches the white you want, another challenge but likely the easiest of them all). However, anything else is probably easier if it can be made to work.
I think part of the problem is fade is not something built into most wifi light devices. I have seen it on zigbee devices fairly frequently though. Even in those cases fade is for white color temps only.
I would expect this level of fade automation between rgb colors could be hard on the hub. I dabbled with a RM rule to gradually change colors on govee devices that have Lan control. There is no doubt that just one device could cause a heavy load depending on how aggressive the fade was. I also added the ability to fade into the driver and again i give directions to users to be careful about setting thr values to aggressive.
I am interested to see how the color anamation app does it though.
Here is the action part of a rule I just did. You would just need to add the trigger.
The simple part of it is that by setting the Hue and Saturation to 0 you basically set it to a red color, but with no red light being put out. As the Saturation increases more red light is output. At the same time the level is lowered from 100% to 20%. I would suggest you start this from a fairly warm White colortemp. As the saturation increases it kind of gets orange as it gets fully red.
I'll give it a try tomorrow. I was thinking, as an alternative, I could probably have one rule take the 3200 k white @ 100% dim down to 20% over 20 minutes and have another rule take it to red about 10 minutes into the dimming process. I guess no guts no glory...

Thanks for your input. What I did was to use the LifX native app to fade from 3000k white to red, over 5 minutes. I also created a HE rule to dim the light from 100% to 20% over five minutes at 5 second intervals. The fade to red starts first and has a 1 minute overlap to when the HE rule starts. So far working good. Tried using the HE rules for both but it was creating too many events and slowing things down. This approach seems to be a nice middle of the ground approach.
