@bidrohini, I have read the manual, but there is nothing mentioned about the protocol used.
@Stuntteam, thank you for your message!!
I am using the Brennenstuhl type with dip switches, presumably using the ARC protocol.
Do you also have a packet structure example for this?

it's about RF-link sorry,
I ony need the Packet structure for the Brennenstuhl RCS 2044 switch for 3 switches

Data:
10;Protocol Name;device address,button number;action;

I lost the remote of my Brennenstuhl RCS 2044 switch. Can any one help me to get them working again.
