The exact code for the brand needs to be in the app. This is not standardized between brands as 433.92 MHz is just a frequentie.
So you could try if it is the same signal and rolling code as another brand but there is not much chance.
You could try to make an app for it but then you also need to understand the rolling code.
Edit, Reading the pdf
433.92 is BTW the most common used frequency and only somfy I was aware of being just below that frequency on .42
Homey can use that also.
I guess not much chance other brands use 433.42.
I put the remote in pairing mode (button on back for 2 seconds) and the awning wiggles. I hit “program” in the app and it seems there is no wiggle, but the app progresses. I choose only up/down function as there is no tilt, but nothing happens with regards to the awning when pressing any buttons in the device on Homey.
