RGB Color from Dimmer

Hi to all.
I'm trying to get the values of a virtual dimmer (RGB color and master slider), so I can push them via mqtt.
The question is: how can I read this values and put them in variables?
Thanks so much for your help.

Reading is the easy part.
Question is what needs to be done with the values ?
Code: Select all
return
{
on =
{
devices =
{
3137, -- idx or 'name' of your RGBW device
},
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'getColor',
},
execute = function(dz, item)
dz.utils.dumpTable(item.getColor() )
dz.log(item.name ..'; color = ' .. dz.utils.toJSON(item.getColor()),dz.LOG_DEBUG)
dz.log(item.name ..'; dimLevel = ' .. item.level,dz.LOG_DEBUG)
end
}

Thanks for the quick reply. I will try it asap.
I've a modified aqaura gateway (
https://github.com/cadavre/miio_gateway) and I'm trying to send, via mqtt the commands to change the colors. I've already achieved the on off (via node red), now I'm trying to change the color.
Do you kn ow a simpler way
?
Thank you!

What is the mqtt command you are looking for?

Code: Select all
return
{
on =
{
devices =
{
201, -- idx or 'name' of your RGBW device
},
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'getColor',
},
execute = function(dz, item)
dz.utils.dumpTable(item.getColor() )
dz.log(item.name ..'; color = ' .. dz.utils.toJSON(item.getColor()),dz.LOG_DEBUG)
dz.log(item.name ..'; dimLevel = ' .. item.level,dz.LOG_DEBUG)
comando = 'mosquitto_pub -h mqttserver -t /mihome/brightness -m ' ..item.level
os.execute(comando)
end
}
The function above sets the brightness level correctly!
So what i'm trying right now is how to get the RGB value in a format like 'fffff' so I put it in a command like
Code: Select all
comando = 'mosquitto_pub -h mqttserver -t /mihome/rgb -m ' ..item.SOMETHING
and to have the item.SOMETHING containing the rgb value.

Can you test this?
Code: Select all
return
{
on =
{
devices =
{
201, -- idx or 'name' of your RGBW device
},
},
logging =
{
level = domoticz.LOG_DEBUG,
marker = 'sendColor',
},
execute = function(dz, item)
local mqttServer = '192.168.192.116' -- Change to IP or name of your MQTT server
local color = item.getColor()
local function osCommand(cmd)
dz.log('Executing Command: ' .. cmd,dz.LOG_DEBUG)
local fileHandle = assert(io.popen(cmd .. ' 2>&1 || echo ::ERROR::', 'r'))
local commandOutput = assert(fileHandle:read('*a'))
local returnTable = {fileHandle:close()}
if commandOutput:find '::ERROR::' then -- something went wrong
dz.log('Error ==>> ' .. tostring(commandOutput:match('^(.*)%s+::ERROR::') or ' ... but no error message ' ) ,dz.LOG_ERROR)
else -- all is fine!!
dz.log('ReturnCode: ' .. returnTable[3] .. '\ncommandOutput:\n' .. commandOutput, dz.LOG_DEBUG)
end
return commandOutput,returnTable[3] -- rc[3] contains returnCode
end
local function toHex(...)
local hex = ''
for _, rgb in ipairs({...}) do
hex = hex .. string.format('%02X',rgb) -- use string.format('%02x',rgb) if you need lower case hex
end
return hex
end
local function createMQTT(server, topic, message)
return 'mosquitto_pub -h ' .. server .. ' -t ' .. topic ..' -m ' .. message
end
osCommand( createMQTT( mqttServer, '/mihome/brighness', item.level ) )
osCommand( createMQTT( mqttServer, '/mihome/rgb', toHex(color.r, color.g, color.b ) ) )
end
}

Works great!
The functions toHex and osCommand opened my mind on how dzVents is working
.
Thanks so much for the solution!
