2. WORK PRINCIPLE OF THE DEVICE  
LoRa (from "long range") is a physical proprietary radio communication technique. It is  
based on spread spectrum modulation techniques derived from chirp spread spectrum  
(CSS) technology. In other words, small number of bytes over long range transmission.  
Excitation of the device is done by pressing any of the buttons (depending on the version,  
whether it is a device with 1, 2, 4 or 6 buttons). After pressing the button, the device loads all  
the settings related to that button and controls the paired devices, if paired with one, but in  
general it broadcasts the button ID. Each of the keys has its own unique ID number whose  
values are given below:  
Button 1 ID = 0  
Button 2 ID = 1  
Button 3 ID = 2  
Button 4 ID = 3  
Button 5 ID = 4  
Button 6 ID = 5  
By pressing any of the buttons, the command is transmitted to the paired devices via the  
LoRa interface.  
2.1 Sending a request for registration/deregistration  
As already mentioned, in order to effectively use the device, it must be registered to at  
least one of our other devices from the allowed group of devices. In order to register the  
device, it is necessary to do the following procedure (valid for all hardware versions of the  
device):  
Press button 1 and hold it for a minimum of 3 and maximum of 5 seconds  
After a proper button press, the device sends a registration request, after which  
it should receive a response from the device that received the request  
If the answer is confirmative, the device is paired, and it is possible to start the  
button pairing process (if necessary)  
A certain type of signaling is proof of the validity of a successful registration  
The process of sending deregistration request is similar and consists of the following:  
Press button 1 and hold it for a minimum of 6 and maximum of 10 seconds
