I am looking for a smart home manufacturer that can do this. The exact manufacturer does not really matter to me.
The main thing is that it is possible.
It should not be open source. I would prefer a "standard" system that does not require extensive training.
I have no specific preferences regarding how it is displayed in the software.
The only important thing for me is to see whether the room was used during the day.
For this, it would be enough if there is a daily overview showing, for example, that there was motion in the room four times and the total duration of movement during the day.

I assume that when you say "smart home," you are referring to the gadget from the hardware store or the pink phone shop, and that there is no existing equipment so far? Off the top of my head, the Shelly Motion comes to mind, as you can view the recent events in the app. However, any app-enabled detector should be able to do that.
I fully agree with Araknis. You can simply search for "smartphone motion sensor" on Amazon and find many options priced between 20 and 50€ (using a Tuya ChinaCloud app solution). The higher-priced sensors usually require some kind of "hub" that acts as an intermediary between the sensor and the phone, but they often offer a wider range of functions.
