@PeteKnight I'm also trying to control my Gaviota awnings with no success, my remote is not from Gaviota but a white label one (It says it uses rolling codes - it's the MX96 https://cloud.motorline.pt/download/manuais/eletronica/mx95-96-97_pt.pdf). I've tried decoding the codes with a cheap RF receiver hooked up with an ESP32 with espHome. I can get some codes sometimes, if I keep my finger pressed for a long time, but none of them work and they do not seam consistent. Since I do not have a raspberry I cannot run that code from Raspi-Rollo.
How did you use audacity to decode the codes? Would you mind sharing the codes you got so I can see if they work here? I have 2 awnings, and I can select which one I control on the remote, does that mean that they are using different codes?
