Color and brightness with a zigbee lamp [Solved]

[EddyG]

I have a Xioami zigbee lamp, which can be set by color temp and brightness.
The Domoticz Gui works (although the setting of color temp cannot be saved)

2019-04-01_09-42-04.png (14.54 KiB) Viewed 4538 times

The command from the gui in the domoticz log is:

Code: Select all

Status: setcolbrightnessvalue: ID: 333, bri: 50, color: '{m: 2, RGB: 000000, CWWW: 7788, CT: 136}'

How do I accomplice this in DzVents? I am using domoticz 4.10580 with dzVents 2.4.16

In dzVents 2.4.16 a couple of new methods for RGBW devices were introduced. Please experiment a bit with the new setHex, setHue and /or setColor methods (see the wiki)
Very much interested in your results.

[EddyG]

I know. I already did, but not (yet) the expected results. The setHue uses m: 1 and cwww: 0000
But I will check further.

[EddyG]

Tnx. Got it working with: .setColor(0,0,0,60,150,150,2,160).silent()
Now some fine tuning for the right brightness and tempcolor.
For me a nice brightness and color temp is: .setColor(0,0,0,80,144,144,2,120).silent()
Now I can change them according to my mood

B.t.w. The color selector in Domoticz does work but and is not saved in domoticz.
I saw in the database that the setting (as from above) is NOT saved in the database in column Color.
I think it should be so it can be used the next time the lamp is switched on.

[Edit] You found it already !

Can you try this ?

Code: Select all

local light = dz.devices(333)
light.setColor(0,0,0, 50, 119, 136, 2, 136) -- setColor(r, g, b, br, cw, ww, m, t)

I tried a getColor() for this device,but that give an error:

Code: Select all

2019-04-01 10:26:38.368 Status: dzVents: Error (2.4.16): An error occured when calling event handler slave overloop

That should nog happen. I assume the color field is not set.
Can you please show what is in the domoticz database for this device to help me identifying the issue so that it can be fixed or at least prevent the Error ?

cd <domoticzdir>
sudo sqlite3 domoticz.db

sqlite>.headers on
sqlite>select * from devicestatus where id = 333;
sqlite>.q

[EddyG]

Here it is. And you are right Color field is not set, and if I fill it in manually in the database the content is deleted after an action.

Code: Select all

I upgraded to dzVents 2.4.17 I get an error with .getColor()

Code: Select all

2019-04-05 13:32:01.866 Status: dzVents: Error (2.4.17): Color field not set for this device

The SetColor works fine, so should not return the .getColor() values?
I know it is not really a color device, but I would like to get back the current color temperature as a value between 0 and 255

[waaren]

Is there any progress with this thing?

Yes. In recent Beta's you will get a message that the color field is not set.

[EddyG]

That is correct, but it is an error.
I would like to have a function to get the color temperature back.
In a separate function or in the .getcolor() function.

[waaren]

That is correct, but it is an error.
I would like to have a function to get the color temperature back.

My understanding of setting color temperature for these type of devices is by /json.htm?param=setkelvinlevel&type=command&idx=nnnn&kelvin=[0-100]
What this does is changing the values ww and cw of the json string in the color field in the database (table devicestatus). This means that dzVents needs the colorfield to be filled in order to calculate a Kelvin value.
Happy to try and implement a getKelvin method if you know of any other way to get this value from domoticz. I do not own such a device so I need a bit of help to investigate.

Can you show me the output of http://domoticz_IP:domoticz_port/json.htm?type=devices&rid=nnnn
and the output of
sqlite> select * from devicestatus where id = nnnn;

after http://domoticz_IP:domoticz_port/json.htm?param=setkelvinlevel&type=command&idx=nnnn &kelvin=1
, http://domoticz_IP:domoticz_port/json.htm?param=setkelvinlevel&type=command&idx=nnnn &kelvin=66
and http://domoticz_IP:domoticz_port/json.htm?param=setkelvinlevel&type=command&idx=nnnn &kelvin=100

Thanks !

The data in the database is for all the kelvin settings the same, so it seems that that setting is not saved in the database. I think it should be saved in the last column 'Color' but it is not.
In the Domoticz web interface the color temperature can be set to to different one, but the settings 'dot' stays always in the middle and cannot be saved either.

Thx for having a look. Maybe the developer of Zigbee2MQTT can help here ?

Tnx.
I created an issue here: https://github.com/stas-demydiuk/domoti ... issues/108

I bought an Ikea Tradfri LED bulb(RGB) yesterday.

it worked like a charm, after some hassle I got it all working.
But is there a possibility to create a custom button so set it to a selected color? So I can hit that button and the light goes to a pre-set red glow.

I got as far as a dummy switch, but now I have to add an action and it says "(Should start with http://, https:// or script://)"

and now I'm seeking help

Thnx!

Have a look at the dzVents wiki on how to create a script triggered by the dummy switch. In that script you can set the Ikea Tradfri LED bulb(RGB) to any color you like.

could look like something as.

Code: Select all

return {
    on = { devices = { "name of your custom button" }},
    
    execute = function(dz, item)
        Ikea = dz.devices(idx of your Ikea bulb)
        
        if item.active then
            Ikea.setRGB(255,0,0)
        else
            Ikea.switchOff()
        end
    end
}

look at the dzVents wiki

Thanks, exactly what I needed!

The script is dzVents code and you saved it as a Lua script
