Thanks for the very useful info !!!
And thanks for testing my future setup with your bits !!
I also have discussed this with the customer service.
And came with up with a solution myself.
You said something like it in your reply.
My solution is as follows (copied from support page) :
"In my new solution, the Timeout bit would be in on/off mode,
e.g. the duration of a sound file is 6 sec., so if I want a delay before the sound file starts, I can set the Timeout bit to maybe 11sec. (look below for why it's 11 sec.)
So when the sound sensor gets triggered, the Timeout bit will send a continuous "on" signal for 11 seconds and then plays the sound file.
Since the Timeout Bit sends a continuous "on" signal for 11 seconds,
in that time frame, every sound the sound trigger would pick up, will be ignored,
because the state that the Timeout bit is in can't be changed while it's working.
So why 11 seconds then, well that's quite simple, in the example the duration of the sound file was 6 seconds.
So let's say we want a delay of 5 seconds, that would be 11 seconds total.
So we must edit all the sound files to include the 5 seconds of silence at the beginning of the sound file.
So in the end the sound file from the example would be 11 seconds in length, 5 seconds of silence and then the 6sec. sound.
Off course if you have multiple sound files, you'd have to see what is the longest sound file in length and make all other sound file the same in length.
I didn't check my sound files yet to see how much the durations differ,
so hopefully they all have somewhat the same duration."
