setKelvin(Kelvin): Function [Solved]

[deennoo]

First step using Dzevents.

My goal is to use the set kelvin fonction on a Yeelight Desktop lamp (as a test, finaly to all bulb and light from various brand all around the house)

I want to use ; setKelvin(Kelvin): Function for an adaptative Kelvin value depending on sun position

my basic LUA time script is :

Code: Select all

commandArray = {}
local mini = 100 --kelvin max range
local maxi = 0 --kelvin min range
local delta = maxi - mini
local wakeup = 60*timeofday['SunriseInMinutes']
local goodnight = 60*timeofday['SunsetInMinutes']
local periode = goodnight - wakeup
local offset = wakeup-periode/2
local color = mini
local time = os.date("*t")
local now = 60*(time.hour*60 + time.min)
if now >= wakeup and now < goodnight then
	color = math.floor((maxi-delta/2)+(delta/2)*math.cos((now-offset)*2*math.pi/periode)+0.5)
end

print('color:'..color)

if otherdevices['test']~='Off' then 

commandArray['OpenURL']='http://127.0.0.1:8080/json.htm?type=command&param=setkelvinlevel&idx=24&kelvin='..color..'' '


return commandArray 

Basic but working as a charme, next step is to retrive kelvin value, and update only if necesseary every 5 minutes

As DzEvent is the futur and i try to translate this with this :

Code: Select all

local mini = 100
local maxi = 0
local delta = maxi - mini
local wakeup = 60*timeofday['SunriseInMinutes']
local goodnight = 60*timeofday['SunsetInMinutes']
local periode = goodnight - wakeup
local offset = wakeup-periode/2
local color = mini
local time = os.date("*t")
local now = 60*(time.hour*60 + time.min)
if now >= wakeup and now < goodnight then
	color = math.floor((maxi-delta/2)+(delta/2)*math.cos((now-offset)*2*math.pi/periode)+0.5)
end



print('color:'..color)

return {
	on = {
		timer = {

			'every minute',		
			
		}
	},
	execute = function(domoticz, timer)
		
		domoticz.log('colordz events:'..color)
	
		domoticz.devices('test').setKelvin(color)

		
	end
}

Log answer is :

Code: Select all

2021-01-23 09:41:00.274 Error: dzVents: Error: (3.1.2) Method setKelvin is not available for device "test" (deviceType=Color Switch, deviceSubType=White). If you believe this is not correct, please report.

My device correctly answer to domoticz api

Code: Select all

http://127.0.0.1:8080/json.htm?type=command&param=setkelvinlevel&idx=24&kelvin=25

Thx for reporting.

I assume the subType 'White'was not in use yet when this dzVents function was created.

Can you please try again after changing line 36 of the file
<domoticz dir>/dzVents/runtime/device-adapters/rgbw_device.lua

from

Code: Select all

		if (device.deviceSubType == 'RGBWW') or (device.deviceSubType == 'WW')  then

to

Code: Select all

		if (device.deviceSubType == 'RGBWW') or (device.deviceSubType == 'WW') or (device.deviceSubType == 'White')  then

If that is successful I will patch it into dzVents and make it available in the next domoticz build.

The Job is done !

Maybe can be usefull to create setAutoKelvin function using "color" function of my script who come from : https://github.com/vil1driver/lua

I am not sure I understand. Is this function different then what is already available in the dzVents rgbw device-adapter? as setColor or any of the other functions?

[deennoo]

On this fonction the name is color but must be named : whitetemp.

Idea is to automatise white temp on Sun position (surely this must be done on domoticz widget side).

Probably a language thing but I do not understand.

My fault, i don't speak about setkelvin function

Spoking about :

Code: Select all

local mini = 100
local maxi = 0
local delta = maxi - mini
local wakeup = 60*timeofday['SunriseInMinutes']
local goodnight = 60*timeofday['SunsetInMinutes']
local periode = goodnight - wakeup
local offset = wakeup-periode/2
local color = mini
local time = os.date("*t")
local now = 60*(time.hour*60 + time.min)
if now >= wakeup and now < goodnight then
	color = math.floor((maxi-delta/2)+(delta/2)*math.cos((now-offset)*2*math.pi/periode)+0.5)
end

Who is a way to make kelvin value follow sun position and make de white temp to be automaticaly adapted to sun position like Philips Hue made, they call it adaptative light

Goodafternoon,
I was looking for something that’s calculates this Kelvin value and stumbled upon your post. Thanks a lot for posting
