Feedback LED of KNX push button showing that a bos scene is active

Hi,

I have KNX push buttons in every room that can trigger 3 room scenes, costumizable by the customer in de bos app. I would like to reflect the state of an active scene in the feedback LED of the button that triggers this scene.

Does anyone have an idea to accomplish this? Preferably in the most easy way? :-)

Thanks in advance,

Regards,

Niels

Hello,

Yes, the scene will only be true, if all the condition of the scene is met, as you have noticed.

Best regards

Hi Ricardo,

The easy way is working :-). I also see that when, for example, the state of 1 light out of 3 in a room scene changes, the scene state wil go from "true" to "false", which is great.

Thanks,

Regards,

Niels

There is no easy way!!! :P

Check if your push buttons allow to configure a separately 1-bit status object for the feedback led (you can then replicate this to the other buttons).

Some KNX buttons don't allow to have a separately object for that feedback led, but several others do, so check that.

So what you want to do is create a group address called something like "Push-button scene X status", and link that button feedback led object.

Add that group address to the bOS.

Easy way:

  • Create a Boolean
  • Add the group address + the Scene.State as references
  • When the Scene.State is true, the address will be set also to true as they are both linked as references

Hard way:

  • Use a task, set the scene state as trigger (allow retrigger)
  • Make a logic, if Scene.state = true, set group address as true, if Scene.state = false, set group address as false.

So, basically take the easy way :P
