[433.92Mhz] Remote configuration

Hi,

New to home assistant here. I got a gate, which is using this thing: https://www.gibidi.be/manuals/gibidi/STURINGEN/F4%20PLUS_7-2008-REV.%2000%20(AS04180).pdf

I have a remote, which sends via 433.92Mhz OR 868Mhz. I have both 868Mhz and 433.92Mhz controllers:

Here is a picture of the Gibidi:

When I connect it to the Windows laptop and send a signal via the remote, the 433Mhz ‘sees’ a signal using the RFXmngr using the settings “Lighting 4” + “Undec on” using the 433.92Mhz.

When I connect the 433Mhz usb dongle to my Home Assistant Yellow and install the RFXCOM integration, nothing happens. I did turn on the auto discovery, but only a random device connected from the neighbours.

My question is, how do I add a new device, or add it manually? Maybe I’m configuring it the wrong way though.

Thanks!
