Hello, it would be helpfull, when the flow item “Setting temperature” of a light would also have the duration setting (like the dim item). Its very usefull to change multi-color-LED-lights between different temperatures slowly. Example: During daytime a light is turned on with cool color (e.g. 4.000 K with 100% dim level). With the sunset this light should gradually change to warm color (e.g. 2.800 K) within 30 or 60 minutes (maybe also dimming to 50%). So there would be a smooth transition in the house for the evening time. At the moment the “Setting temperature” item in the flow doesn’t provide that option. ---

I noticed, the “duration” option is available on **Innr FL 120 C LED-Strip** but not for Ikea **TRADFRI bulb E27 WS opal 980lm** or **Ikea TRADFRI bulb GU10 WS 400lm** All those lights support differen Kelvin-values ---

Well, it really depends whether it can be technically supported. You should contact the specific app developer about it. Some brands support such feature natively. For others the developers need to clarify if it is feasible to be “emulated” technical wise. In any case, there are also a few apps which try to circumvent such limitations. Like this one: [Chronograph App für Homey | Homey](https://homey.app/de-de/app/nl.fellownet.chronograph/Chronograph/) ---

Thanks for that insight, Shakesbeard. So I guess Ikea lamps don’t support that feature. ---

[This post](https://community.homey.app/t/duration-to-color-temperature-is-gone-beginner/43993) suggests that it was actively removed from the IKEA app. ---

Maybe take a look at this post: > [@DIY circadian rhythm based lighting](https://community.homey.app/t/diy-circadian-rhythm-based-lighting/33348/17): > > I did it much easier… Sun Events app has a color temperature tag which changes during the day the right way. The only issue was to solve, this value is in Kelvin, however I need to transform it to percentage because Homey can set percentage. Here you are: Works flawless, but you need CCT light source or RGB-CCT because RGBW solutions are too red or too blue at 100% and 0%, while CCT gives the best result.
