Help needed with how to automate a dusk to dawn colour temperature and intensity change

[bedfellow]

I have a Zigbee bulb that is both dimmable and colour change and I would like to adjust these parameters throughout the day, i.e.start with low brightness and colour temperature, ramping it up for 6 hours and then back down for 6 hours. I can’t figure out how to do this with an automation however, so can someone give me some pointers?

One of these should do the trick:

Adaptive Lighting automatically adapts the brightness and color of your lights based on the sun's temperature but stops when you manually make a change

Adaptive Lighting component for Home Assistant [image] Try out this code by adding GitHub - basnijholt/adaptive-lighting: Adaptive Lighting custom component for Home Assistant to your custom repos in HACS and install it! This custom_component is also being added to core, see this PR, although it might take a looooooong time before it makes it in. The adaptive_lighting platform changes the settings of your lights throughout the day. It uses the position of the sun to calculate…

This gives your environment a more natural feel, with cooler whites during the midday and warmer tints near twilight and dawn. Circadia…

Periodic lights blueprint

Periodic lights Github Gist: Periodic lights · GitHub Github Gist for RGB lights Periodic Lights XY · GitHub Introduction Have you ever wished there was an easy way to have your lights adjust themselves based on the time of day? Well, this blueprint does just that! This blueprint progressively changes the brightness and color temperature of lights throughout the day (this runs 24 hours). This method indexes the light properties to midnight and fits them to a sin function (hence periodic). M…

Circadian/Adaptive Lighting NodeRed

Hello all I would like to share with you my implementation of circadian/adaptive lighting. It’s done with the use of NodeRed and some custom NR nodes. The article consists of several parts: Motivation Circadian implementation Feeding lights implementation Maximum light mode implementation Please note, while Circadian implementation is pretty universal, the way of controlling lights described in points #3 and #4 is strictly dependent on used components. Article considers using Shelly Dimmer …

Perfect, thanks for the advise. I will try the various options
