I found that this is quite easy with Automation: for example, one press of the smart button to switch two cameras (one C425 and one C520WS) to Privacy Mode OFF and emit a 2 sec sound via the H200 hub.

The point is, even if in Automation the "if" condition is set to "both cameras switch to Privacy Mode OFF" (this is the condition I want in order to be sure that the mode OFF is set on both cameras), the hub emits the sound before the Privacy Mode Icon of both cameras shows that Privacy mode is OFF.

Is this just a delay in the icon display change? Any suggestion, please?

You are right, this kind of automation is a bit tricky.

With one and two smart button presses I'm able to switch the Privacy Mode ON and OFF respectively, at least judging by the camera icons switching off and on. During the next few days I'll be checking with the smartphone whether the Privacy Mode switching actually occurs on the cameras, then when I'll see that this kind of use of the smart button is reliable for my purpose I'll stop using the smartphone altogether for such a simple task.

Yet, I'm still pursuing the goal to have some kind of audio or visual feedback when the cameras actually switch to Private Mode ON and OFF. Wouldn't this be an useful addition to Automation?
