My friendly electrician forgot to connect a switch in the bathroom 🙄 and suggests installing a motion sensor.
It will automatically turn the light on when you enter the (small) room. That’s fine.
But what about switching it off?
What I would like is for the light to stay on as long as someone is in the room, and then turn off shortly after they leave. The timer setting is probably responsible for the latter.
It would be annoying if it always turned off, for example, after 5 minutes (set time), and you have to wave around to turn it on again (I’ve experienced this before with an outdoor light).
There are different types of sensors that detect "movement":
Infrared
Microwave
Photocell
Does anyone know what I should specifically look for when buying the device?

xMisterDx12 Dec 2022 22:58With the right components, you can program whether the light in the guest toilet turns on automatically after 2:37 AM. It can also be set so that the light in the guest bathroom stays off if the hallway light is on. Or it can be programmed to stay off when it’s darker outside than a certain level, because then people would be able to look inside. If the neighbor’s outdoor lighting is on, they can’t look inside...

Oberhäslich27 Feb 2023 12:21Question about installation. If I want to have a motion sensor installed in the hallway on the upper floor, do I also need standard light switches? Or is the motion sensor alone sufficient? I imagine that if, after some years, I no longer want to use the motion sensor for reason X, it wouldn’t be possible if only the motion sensor is installed, or if there is only one light switch. That would be inconvenient for a larger hallway.
How is this handled in the hallway on the ground floor when there is an open living area? My concern is that the light in the hallway would turn on every time someone walks from the kitchen to the living room through the open area. The only solution would really be to position the sensor facing the opposite direction, so it does not cover the open living area. But then there is no wall to mount it on.

Why would you no longer want to use it? In theory, KNX radio communication would also be possible then.
Detectors are available in many different types. It is best to install them on the ceiling, not on the wall. There are detectors that cover multiple directions. For each direction, different sensitivity levels, brightness values, etc. can be set. This allows for easy separation of rooms.
You just need to use the right detectors, position them correctly, and configure them properly.

How do I communicate this to the system?
