Kelvin only applies defaultBrightness, defaultTemperature and schedules. Nothing else.

[Dan0sz]

Hi!

Maybe I'm missing something here, but I was under the impression that Kelvin will modify the light color and brightness to simulate daylight.

As I understood this, it's a sort of automatic process. Just like flux. In my case, Kelvin only applies the values specified under defaultBrightness and defaultTemperature, and it follows the defined schedules afterSunset and beforeSunrise. In between sunrise and sunset it never-ever simulates daylight. It just follows defaults.

Is this intentional and did I just misunderstood this app? Did I misconfigure something? Or is something indeed going wrong?

I didn't see anything notable in the log file. There was once an i/o timeout when it was validating the time stamp, but that occurred once and never returned.

I installed it using the docker image. I don't see anything being off.

Here's my config.json:

Any help would be appreciated!

Update: by removing the defaultColorTemperature and defaultBrightness I'm starting to notice that Kelvin takes over a bit more often.

Now I'm getting a lot of these warning messages:

time="2021/07/12 09:17:06" level=warning msg="Validation: Invalid ColorTemperature in &{ColorTemperature:87 Brightness:1}"
time="2021/07/12 09:17:06" level=warning msg="Validation failed in calculateLightStateInInterval"

So, Kelvin doesn't seem to respect the temperature ranges of light bulbs. Even though it detected them properly.

Hi @Dan0sz

Sorry to resurrect this comment, but did you have any luck with the approach above? Given what I've read about it, I'm surprised how limited the tool seems to be and I wonder if I'm missing something.

Hi! No, unfortunately. After a while, I just gave up and stopped using it.
