I have tried different things, the thing I have changed, is the type of value who would be send from the sensor.
The default :
send(msg.setSensor(i).set(temperature,1));

gives me the following error in Control 4 :

number 1
string UPDATE
parent 26
room 1
subcategory 0
[string "Lua Code"]:120: bad argument #1 to 'SetVariable' (strValue should be a string) (ReceivedFromProxy)
altid 5;0
id 40
temperature 23.5

I tried to add the lines :

char charVal[6]; //temporarily holds data from vals
dtostrf(temperature,6,1,charVal);

and changed the send to :

send(msg.setSensor(i).set(charVal));

But the same happens

If I cast the temperature to int I got the it, but without decimals

If I try with :

String  string = "24,8";
send(msg.setSensor(i).set(string));

No error in Control4, but the sent temperature is 1

Maybe normally not. The Vera Controller reads the value nicely whatever which type this is. But the Vera are connected to a Control4 controller, this wants the value to be a string or int. I have managed the value to be an int, but then I do not have any decimals. So it would be nice if I could have it to be a string

I am pretty new to programming and Arduino. I have made a temp sensor, and all are OK, but I need to send the value to the controller as a string, or a char. How can I convert the float to a string.

I have tried with :

char charVal[6];
dtostrf(temperature,6,1,charVal);
send (msg.setSensor(i).set(charVal));

It converts right, but when I got the readings in the controller I got 20, if the temp actually are 23.

Please help
