Updating devices of a scene Topic is solved

[Hesitated]

In my living room I have a table with up to 5 (not yet installed all) Hue lights above it.

Now I have made a group and I can turn the group on or off, but I would like to update the colour and brightness for all the devices belonging to that scene.

The Domoticz interface doesn't have that option and the API-documentation is lacking this too, although the parameter updatescenedevice is mentioned.

With the API-call:

Code: Select all

/json.htm?type=command&param=getscenedevices&idx=2&isscene=true

you'll get a list with all the devices of a certain device.

{
"result" : [
{
"Color" : "{\"b\":255,\"cw\":0,\"g\":255,\"m\":3,\"r\":255,\"t\":0,\"ww\":0}",
"Command" : "On",
"DevID" : "374",
"DevRealIdx" : "374",
"ID" : "5",
"Level" : 24,
"Name" : "Lamp eettafel 2",
"OffDelay" : 0,
"OnDelay" : 0,
"Order" : 5,
"SubType" : "RGBWW",
"Type" : "Color Switch"
},
{
"Color" : "{\"b\":255,\"cw\":0,\"g\":255,\"m\":3,\"r\":255,\"t\":0,\"ww\":0}",
"Command" : "On",
"DevID" : "375",
"DevRealIdx" : "375",
"ID" : "6",
"Level" : 24,
"Name" : "Lamp eettafel 4",
"OffDelay" : 0,
"OnDelay" : 0,
"Order" : 6,
"SubType" : "RGBWW",
"Type" : "Color Switch"
}
],
"status" : "OK",
"title" : "GetSceneDevices"
}

To set an individual device you can use the API-call:

Code: Select all

/json.htm?type=command&param=setcolbrightnessvalue&idx=130&color={"m":3,"t":0,"r":0,"g":0,"b":50,"cw":0,"ww":0}&brightness=100

Does this mean that:

Code: Select all

/json.htm?type=command&param=updatescenedevice&idx=XYZ&color={"m":3,"t":0,"r":0,"g":0,"b":50,"cw":0,"ww":0}&brightness=100

is the correct API-call to set the color and brightness for a device in a scene?

But which idx should i use? The DevID's or the ID's of the scenedevices?

No. just use the setcolbrightnessvalue JSON

But which idx should i use? The DevID's or the ID's of the scenedevices?

The device ID as seen on the devices tab

Can you try this ?

dz.utils.stringSplit require dzVents >= 2.4.19 (domoticz V4.10728)
dz.utils.dumpTable require dzVents >= 2.4.17 (domoticz V4.10602)
dz.utils.groupExists require dzVents >= 2.4.28 (domoticz V4.11079)

It worked.

Although I had to change it a bit as I'm still on version V4.10717, instead of dz.utils.stringSplit, I had to use:

Code: Select all

        local parms = {}
        local index1 = string.find(item.value, ';', 1, true) - 1
        parms[1] = string.sub(item.value, 1,index1)
        dz.log('parms[1] = ' .. parms[1], dz.LOG_INFO)

        index1 = index1 + 2
        local index2 = string.find(item.value, ';', index1, true) - 1
        parms[2] = string.sub(item.value, index1, index2)
        dz.log('parms[2] = ' .. parms[2], dz.LOG_INFO)

        index2 = index2 + 2
        local index3 = string.len(item.value)
        parms[3] = string.sub(item.value, index2, index3)
        dz.log('parms[3] = ' .. parms[3], dz.LOG_INFO)

But that is just a matter of coding and maintainability...

Thanxs again!

Nice
If you look in dzVents/runtime/Utils.lua of a recent Beta and search for stringSplit you will find the function self.stringSplit

You can copy that function and merge it into the script as

Code: Select all

function stringSplit(text, sep)
	if not(text) then return {} end
	local sep = sep or '%s'
	local t = {}
	for str in string.gmatch(text, "([^"..sep.."]+)") do
		table.insert(t, str)
	end
	return t
end

Same approach could be used for groupExists and dumpTable. No magic involved here.. Just plain Lua.

At first it did not work.... Until I saw that ds.utils.stringSplit was not correct...

Now first back to work, maybe I'll look into this later...

Thnxs again!
