RFLink: Protocol Reference
3-1-2022
The use of this protocol is free for both server and client sides of the implementation as long as you notify us.
General description of commands and data fields
Data is send serial (via USB) as "text" at a speed of 57600 baud (N,8,1)
It is sufficient for a server to open a port and listen to the RFLink data.
Each incoming text line contains information about data that has been received via RF signals.
In order to talk back to RFLink to issue RF commands or to make changes to settings, a text line has to be send that is terminated with CR/LF.

Note that for sensors that only report data values like temperature, windspeed etc., only the data value itself and the ID are needed for Home Automation programs.
Name labels are included for cosmetic purposes describing the detected protocol.
Instructing RFlink to send a command via RF:
For switches, the protocol name itself has to be stored in the Home Automation program and re-used on the transmission side.
When a remote control is used to control a device, RF data is received and translated and data like below will be send from the RFLink Gateway over USB:
20;3B;NewKaku;ID=cac142;SWITCH=3;CMD=OFF;
When the state of this switch needs to be changed the following command has to be send to RFLink:
10;NewKaku;0cac142;3;ON;
The name label (here "NewKaku") is used to tell the RFLink Gateway what protocol it has to use for the RF broadcast.

10;RTSLONGTX; => Toggle RTS long transmit ON/OFF
Device creation using the Echo command (Node 11):
RFlink auto detects remote control signals and home automation software should create the device automatically.
However, sometimes the original remote control is not available anymore (broken/lost/etc.)
For this purpose Node 11 commands can be used from the home automation software.
The user can input a command as below:
11;20;0B;NewKaku;ID=000005;SWITCH=2;CMD=ON; => 11; is the required node info it can be followed by any custom data which will be echoed
RFlink will reply with
20;D3;OK; => Notifying that the command has been received
20;D4;NewKaku;ID=000005;SWITCH=2;CMD=ON; => sending the data "as if" a remote control button was pressed.
The home automation software can then process the received command as any other RFlink command.
