Say I want all of these bulbs to be 4000K if time is between an hour before sunrise and sunset, whether they are already switched on or not. Do I still use a time trigger, that will set the correct color temperature also for lights that are off?
What if I change the color temperature manually, then there is no way to trigger color temperature to be set whenever the light is switched on the next time? For example always being 4000K when it’s switched on during the day. Although that takes away the possibility to override the color temperature.
I thought my IKEA bulb could only use set color temperatures at 2200K, 2700K and 4000K. But it seems like it can actually be set to values in between as well.
How would you set up Circadian lighting using SharpTools rules? Only use 2700K during the golden hour of sunrise and after sunset and 4000K from sunrise to sunset? Or gradual values in between? Or using fadeLevel to gradually change level over time?
I’m using SmartThings and there are Edge drivers that can simulate Circadian lighting. But I’d rather have some more control of it myself in this way.
Depends on the light or which driver its using. Sometimes setting the temperature will automatically turn the light on too.
If you change the temperature manually you could still have rules in sharptools that are aware of that. Just depends on what you are trying to do. You could react to the light coming on and change the temp then but it will at least temporarily be at the old temp before the rule kicks in.
Even better would be if this color temp variable could be calculated, in order to have a range of values rather than a few fixed ones. I guess something like that is actually better suited for a device handler in SmartThings, though. And currently maths with variables in SharpTools isn’t possible anyway.
