Fibaro Smart Implant IN1/IN2 invisible

Hi! I’m a HA newbie trying to set up a Fibaro Smart Implant for controlling my garage door. I have disconnected the preset IN/OUT connection by changing the Local Protection State and open/close garage door works perfectly using OUT1. The garage door motor provides two connections which is either open or closed depending on the position of the garage door . These I have connected to IN1/IN2. My problem is, however, that I cannot see the binary sensors in HA! I have tried to exclude/re-include/heal several times, I have tried secure/insecure inclusion. I have even bought a second Smart Implant in case the first one were faulty, but the problem is the same. I’m probably doing something wrong here, but cannot figure out what that could be. Can someone please guide me in the right direction?
