Hi!

Thank you for the code!

I have installed a RGBW LED and would like to use this code, but I do not have a physical temperature sensor outside.

How canI get the Yahoo weather temperature and store it in the variable 'OutsideTemperature'?

Thanks for the help!

Forget it, I solved it myself.

Hello SteffX,

I played a bit around with your code made a bit shorter.

As always not tested... and I have just had a large meal and a glass of wine or two.

As you have a table why not use the index rather than the loop. As I say not tested but LUA is so weakly typed think it will work.

Robert,

Your change gave an error in line 8 the '=' is to close ????

hmm try that.

I was a bit lazy and thought that I would get away without need for [] with numeric index

Call the Midwife now. ahhhh UK TV at christmas. Large Brandy needed.

[Guest Charly]

I have fixed it According to your indexed table included the []

Also took out the Temp variable because there is no need if the index is the temperature

Thanks.

Nice, should save a bit of processor.

It should also work with an integer. Will have a go when my HC2 comes back from repair.

for our friends that live closer to the equator an elseif >34 would be the finishing touch

I wish

THe temp could be useful if your sensor is slightly out... use temp to hold correct temp?

You may need to floor the value so it is round integer.

HI guys, I try to make the same scene but with temperature of my room.

But HC2 cause problem:

"[ERROR] 12:54:29: line 51: attempt to index local 'v' (a nil value)"

[Guest Charly]

Easy to solve.

Your temperature is not an integer, with floor it round to an integer.

local OutsideTemp=math.floor(tonumber(fibaro:getValue(XXX, "value")));

XXX = DeviceId of your temperature sensor

Charly,

thanks it work, but what if temperature for example 5.8C it will 6C

And what about Math.round(х) why it is not working?

[Guest Charly]

Hello Dima

math.floor(x) will not work the function does not exsist.

here is a workaround

function round(num)

return math.floor(num+.5)

end

Good luck

Charly
