Programming presence detectors

[ergo14]

In my house i have BEG PD11-KNX-FLAT-DX detectors.

Now I want to ensure that we can switch light on in the bathrooms via buttons and via detector.

So I have 2 adresses:

One "switching" on the detector, and another one "manual switching" on the button in the bathroom. Manual switching GA is added to "manual influence" input, in the detector, and it works correctly. But I was thinking - if my presence detector gets broken or something happens to it, then the buttons will not be able to turn the light on.
My thinking was that both switching and manual switching GA should be set on the actuator to ensure operation in this scenario.
But that means that pushing a button results in emitting both on telegrams to the actuator. Is this the best practice to do this?

It is possible but not necessary.

Then you go to the switchboard and turn the light on, and afterwards your start your ETS and reprogram the switch directly.
Don't worry too much, KNX is pretty durable.
