Thank you for looking into it. Each of the button on the Bali/Somfy 2-Button remote is a single press. As requested here is the command class snapshot below.
In the Groovy days, Eric Vitale wrote a driver that works well, it did not survive the migration to edge. Here is the link to the Groovy driver if it helps.
I also have the 3 Button Somfy/Bali remote somewhere if we need to fix that one too. It has an additional button call “Home” in addition to the 2 single press button as above.
