Io-homecontrol / velux - something's in the bush

I bought another Velux remote, and took it apart. I figure I can interface it via dry-contacts (using arduino or similar). I took some pictures of the board if anyone’s interested. There’s a TON of test points and it really feels like you should be able to get it to do something useful via them, but I don’t have the time nor skills, I suspect, to reverse-engineer them. So I’ll probably just build something to “press the buttons”, sigh. LMK if you’d like to see pix of the board inside the (multi-device) remote.
