I’m probably going to get tomatoed again, but in a smart home, a guest bathroom should have no switches at all. After all, guests don’t have anything to press there.

Are they at least allowed to choose when to start the toilet flush, or is that controlled by the software as well?

I’ve tried this in the guest toilet, but I will still have a switch (just not at the entrance). The electric towel warmer somehow needs to be switchable, and the window can only be opened by motor. I just lack the appropriate sensors to control this reliably. Any tips?

We don’t have any switches in the guest WC. The skylight turns on during the day if needed. In the evening and morning, the mirror light is added. At night, only dimmed light without the mirror is on. The towel radiator turns on about 1 to 1.5 minutes after showering starts. That’s enough (thanks to a 60°C (140°F) supply temperature) to have warm towels after showering. The mechanical ventilation system automatically switches off during showering (to keep the heat) and switches to maximum mode after showering for quick air exchange. Everything turns off by itself again. Works perfectly. Some tinkering and testing was necessary though.

Like Steffen’s approach, it is quite an elegant solution.

I don’t see any issues with the lighting; that’s straightforward.
Which sensor triggers the heating? A contact sensor on the shower supply line? Which one exactly?

The windows in the room can only be opened electrically. If a guest uses the bathroom and wants to ventilate, there needs to be a way for them to activate this. I haven’t found any kind of sniff test device for the drain yet :P

Then please use switches that everyone can "understand." My brother-in-law also has some kind of smart home system for his lights in his house, but with switches as well.

This was not about smart systems, but about switches. In my case, they are allowed to have an arrow pointing up and down.
