ProppFrexx ONAIR User-Forum

Why do the Cartwall lights (D&R Airlite) stay on after closing ProppFrexx?

I'm using the GPIO Client in ProppFrexx On Air to control the lights and the fader and button start , but as soon as I close the program, the lights remain on of the cartwall on my D&R. Is there a way to automatically turn them off when ProppFrexx is closed?

Thanks in advance!

Of course there is.
You can for example use the ProppFrexx ONAIR event "Application.OnShutdown" or the "Others.OnDRAirliteStopped" to set the LEDs off.
E.g. use this command to turn all LEDs off:

can you give me a tuturial how to set this on the closedown of propfrexx on air is this in the event page

There is already a tutorial on how to define events - see the Tutorial videos!
As it is just a simple event (which I already told you), I will not make an extra tutorial! What is so complex with it (I even told you the event names)? Just try and experiment a little yourself...or do you a video for everything? If yes, sorry to disappoint you.

okay when i do that its not Turning off the lights

I will check, if at that point the connection to the GPIO Client is already cut/closed.

its on and when i close the program i see GPOI client Connection Disconnected

You can not see, if the internal GPIO processing within PF is already stopped. This is happening async and it might be, that the internal connection is already closed when the asyc task to the GPIO client gets processed. I will change to a sync processing for the Application.OnShutdown event in the next version.

You can define a user command (e.g. Custom.OnUser1) for now to turn off all lights on your D&R.
