I have a project with a trigger button which triggers an KNX relay which is assigned normally closed. so if i send 1 the feedback will be 0 and vica versa. This gives a problem with the trigger button because it gets feedback 0 and so wants to send 1 but the relay already got 1 so does nothing and by another press it will send 0 and then the relay will change and gives feedback 1 and so on. I thought when if change feedback from channel to invert channel this would solve the problem, but this doesn't change anything. How do i solve this and what is the difference between feedback channel and invert channel ?
