LightEffectSleep Changes Color Temperature of Light

linkian19 — Wed, 20 Sep 2023 20:53:09 GMT

Hello all!

I have an automation setup that runs the LightEffectSleep action on my bedside lights. All of that is working as expected, however, whenever that action it runs it changes the Color/Color Temperature of my lights. This is unexpected behavior, as I would assume that it would just use whatever color the light was currently set to.

In my investigation it seems that the color temperature will change AGAIN even if I set it back to what I want on the next iteration of the light effect.

It does appear that my manufacturer of my lights did not implement the "lighteffects" functionality so that does mean that the Automation is simulating the sleep effect per Google's documentation. But even then, I wouldn't expect the color to change.

Documentation here: https://developers.home.google.com/cloud-to-cloud/traits/lighteffects#en-us

Has anyone else had this experience? Any ideas on how to prevent it? Any help would be appreciated! Thanks!

Hello !

You can't set the color of your lights just before the "lighteffect" ?

I can, but it seems that the next time the light effect runs its next iteration it changes it back to whatever the light effect wants it to be.

I tested this by setting another trigger to change the color temperature of the light if the light wasn't the temperature I wanted. While the light effect was running I could see the light updating constantly.

Very odd behavior.

Maybe color & temperature are "embeded" in the LightEffect code...

I don't know what kind of lights you have, but with Philips Hue, it's possible to make wake and sleep effects in a scene. If it's possible for you, you could do that and launch that scene instead of the Google LightEffect.

Did anyone solve this problem? I’m being irritated by the same phenomenon. All I want is lights to fade in/out over 30 minutes to the color of my choice, but the sleep/wake functionality always changes the color.

Just bought a new multicolour smart bulb to replace a dying warm white smart bulb as it's brighter/ longer life/ etc etc.

The stomach churn I just got from asking google home to sleep the light only to be bathed in disgustingly clinical cool white light, closely followed by a wave of disappointment that Yes it is a known issue and No there's no plan to fix it 😤
