ᐅ Motion Sensor Instead of a Switch?

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?

What Kati describes — and similar situations — is something I want to avoid.
Through the posts here, I got the idea for a wireless switch with a receiver at the lamp. I haven’t found one yet and am still looking.
There are some with batteries (which I don’t want), and so far, I haven’t found any pictures of the parts to be installed.

Thank you 🙂

If you’re planning to set up a smart home anyway, you can also use a flush-mounted actuator.
You can add a motion sensor as well, but it’s not mandatory.

You can place a small lamp next to the changing table, so that’s not really a disadvantage.

Provided the electrician hasn’t forgotten the cable to the light fixture. Normally, that cable runs to the switch... so if it’s missing at the switch, it will be missing at the ceiling too.

They can still connect it later, as long as the cable is there.

There is no such thing as a “wrapped child,” but it would be good if the switch next to the door worked normally.

There is power at both the switch and the light fixture, but they are not connected so that the switch can control the light. This is because the light’s power line also feeds an electric bidet and sockets that require constant power, and there are only 3 wires (instead of 5).

Feel free to keep thinking about it 😉 , but my problem is solved 😎

Then you definitely need a smart light that can be controlled wirelessly.

I assume that when the door switch is activated, it sends a signal to the light switch. The lamp itself is just the lamp.

There will be four GU10 sockets with different LEDs. Three of them will project their focused 10° beams onto a gold-plated, slightly curved surface above the shower, and one regular LED will illuminate the bathroom cabinet. All four will be installed together, hidden behind wood and glass. The receiver switch can also be placed there.

If this works out, there will of course be a picture. (that might take some time :cool 🙂

In some situations, I would also like certain lights to turn on automatically. But mostly in the utility room. Especially in bathrooms and hallways, I don’t want that, because these are usually times when I don’t want to be illuminated or where the main light would be more annoying. In the restroom, if I just want to quickly grab tissues or cream, or in hallways, as @kati1337 mentions.
It also depends on whether the guest bathroom is visible from the street. Some people wouldn’t want to be... you know... on display at night... in the evening... 😎
