LUA, send email when Temperature is high

[flopp]

I am using this script to detect if the drawer is open for my "TV-electronics". My kids start PS3 but forget to open the drawer. That's why I made this

Create a user variable named "AppleTVVarm", of course you can name it to what you like but use my names first then after you tested it and it works you can change the names. Device name must be change to your device name If variable is 1 it means that the temperature has reached its limit.
If the temperature get above 35 it will send me an email and when it goes below 30 it will send a new email, so I know it gets cooled down.
Varm means Warm
Sval means cool

commandArray = {}

local function update(cmd)
if devicechanged[cmd] then
    local vari = "Variable:"  .. cmd .. "Varm" --add Varibale: before device and Varm after device
    local varm = cmd .. "Varm" --add Varm after device
    --print(cmd)
    --print(varm)
    --print(vari)

    temperature = tonumber(devicechanged[''..cmd..'_Temperature']) --read temperature from device, if device have more than only temperature
    if (temperature > 35) and (uservariables[varm] == 0) then --if temperature is above 35 for the first time
        commandArray['SendEmail']=''..cmd..' varm#""#abc@hotmail.com' --send email
        commandArray[vari] = "1" --set variable to 1
    end
    if (temperature < 30) and (uservariables[varm] == 1) then --if temperature is below 30
        commandArray['SendEmail']=''..cmd..' sval#""#abc@hotmail.com' --send email
        commandArray[vari] = "0" --set variable to 0
    end
end

end

update ('AppleTV') --device to read temperature from
update ('PS3')
update ('Stereo')

return commandArray

copy the code and create a new script in Domoticz, select LUA and Device otherwise it will not work
