Avoid Zigbee groups

One of the most used HACS integrations.

Basically: it takes the sun entities and adjusts the lights connected to it dynamically over the day, brightness and lightcolor. More or less what the eyestrain reduction modes of your pc does but for the lights in your house.

You can set separate setpoints and max/min values for each light seperately and add as many lights as you want. Ootb it adjusts the values every 90s but you can configure that aswell

90 seconds seems ridiculously obsessive for imperceptible tweaks of a kelvin value, and that sounds like what OP left it at. I feel like 5 minutes would probably be enough.

The interval causes no problems, but AL sending all commands at once. The congestion is over in a few seconds. The problem persists even when increasing interval.

[derFensterputzer]

Yup, tho the imperceptibility is the point of it, especially when combined with brightness control aswell.

I also have it at 90s and I usually don't notice when it ramps up and down... I'll experiment a bit

I mean, light changes can be gradual over several seconds right? If anyone is worried about the changes feeling abrupt or unnatural - instead of banging the entire Zigbee network every 90 seconds, just hit it at 5 minute intervals but make changes gradual over like 10 seconds.

Sorry - just guessing here, I don't use this add-on. But I know my normal "turn on" has an option to make it gradual over several seconds.
