2KM Long Range RF link kits w/ encoder and decoder

New at this but do understand basic electronics.

My goal:
15 simple one way transmitters that has one input (on/off) to one receiver that can decipher which one of the 15 transmitter is transmitting. Ultimately to be fed into a computer probably by some simple USB.

Also if there is another of the same transmitter/receiver combination near by with its own cluster of 15 transmitters that there will be no interference. IE> If bought a set of two of these 2KM devices running next to each other.

Is the input of the transmitter on this 2KM device individually addressable making it a binary up to 16 discrete binary combo so the receiver outputs the binary combination or are they simply on/off state of the 4 data line?

So ideally I like to get 1 receiver and 15 transmitter as a set (each transmitter hardwired for a specific dataline binary combo) and looking to put together multiple sets all working close to each other gathering switch states from their paired transmitter(s).

thank you very much for you time.

Dear customer,

2KM Long Range RF link kits w/ encoder and decoder seeedstudio.com/depot/2km-lo … th=139_140 .
This is only one that can communication as 2KM. And it can not decipher one of your device.
So actually what feature do you want to build up?If you want to precise control of each one, can achieve this functionality by coding.
