smart home Arduino project with MIT app inventor

Hello Please I need some help because I'm trying to design an application that can control a smart home with an Arduino controlled with a smart phone (I did the application using MITapp inventor).
  
An application that allows me to control the opening and closing of shutters, lighting of the house, a sensor to measure the temperature and humidity (DHT11).
 
 But I have a problem with the temperature display and humidity as it appears on the same label and what should I do to display the temperature in a label and humidity to another label? Thank you kindly help me 
Here is my program:

I tried with this programme but it doesn't work

You need a way to mark your sensor reading messages to identify them as either temperature or humidity, so the receiving blocks will know where to show them.

For example, println("T=",t);

println("H=",h);

and when you receive on the AI2 side,

If connected then

   if bytes available > 0 then

     set m = incoming message

     if the front of the message is "T=", copy the rest to the temp label

     if the front of the message is "H=", copy the rest to the temp label

See the text blocks for length(), split at, segment.

You are probably receiving both T and H in the same message m.

Try setting your BT Client Delimiter Byte to 10 in the Designer, and set the BTClient.ReceiveText Number of Bytes to Receive to -1.

This will get you only one reading per message because it will split them at the Line Feed.

thank you for your reply

I have a question:: Can I take a break in the application (as I do in the Arduino (delay))?

can i do this with timer ??

AI2 has no wait() block,

but you can use a Clock from the Sensors drawer and set it as a timer.
