Transceiver APC220-43

[kawthar]

Hello,

I'm now working with my final year project on SMART HOME POWER MONITORING SYSTEMS where 3 transmitters (slave) are used to send data (power consumption) wirelessly to a receiver (master) that is USB-connected and the data will be displayed in LabVIEW. The transceiver used is APC 220-43 Module. The transmitter is connected with RX/TX of PIC16F887 each where a current sensor is mounted on the wire of each appliances. The problem now is I honestly have no idea on how to do the block diagram of this project as I edited here and there from discussion posted in the forum. I have tried to calibrate at first with the example of basic serial write & read but nothing happened when run button is pressed. 
It works fine with X-CTU where the reading appears. 

Can somebody help and guide me on how to actually connect the block diagram for this project to be a success? I'm totally lost here . Data parsing and three different loop will be needed I reckon for the master to detect which home appliances do the user want to interact with because each appliance will have different circuit, current sensor and transmitter.

Million thanks!
