Bathroom fan automation: switch with light and moisture sensor?

Hi,
I have a request for experienced forumers.
I am starting the adventure of automating devices in the house. At the moment I have an HA and a sub switch on zigbee for a light on the stairs.

I would now like to automate the fan in the bathroom and toilet.
This is where the question arises. Is there a switch with a built-in light and possibly moisture sensor?

Stopping at the toilet. My expectation for the fan is:
when the light is switched on "switch on" (I have a toilet without external windows so switching on the light is sufficient signal that the fan should be switched on)
when the light goes out, "wait a set time and switch off".
A simple thing assuming we have a total non smart fan.
One light or presence sensor +switch, e.g. SONOFF Basic.
And although I don't currently know how to put it all together to make it work, I assume I can figure it out... step by step.
The problem is that it's a lot of elements, each one looks different, each one has either a battery or a cable. Generally it doesn't look attractive and I'd have to think hard to hide it.
In the bathroom, additional data such as humidity. so an additional sensor.

Is there a switch with a built-in sensor? I don't know something that will have an input at 230 and a controlled output.... depending on various parameters... e.g. lighting, humidity etc.
Assuming of course that... the price is reasonable... or is the option between some expensive smart fan or a sensor sticky?

Many thanks for your help

Do you have a false ceiling?

In the toilet no, in the bathroom partly yes.
All in all, right, in the bathroom it can be accommodated on the false ceiling, although this will require a little remodelling at my place, but in the toilet it's a no-go.

In a suspended one, you pull the wires from the lamp to the grille and don't have to automate anything.

Why any smarts here at all? After all, there are fans with a humidity sensor, with a timer. Ready-made solutions, simply connect to the lighting.

and the spell was gone but you know, it would be ..smart ;P
well, maybe I'm right, maybe I've overcomplicated a simple thing and want to make it more complicated

>>21425185 I think it is possible to make such a switch myself, using Arduino or ESP, but is it worth it, and you need to have the time to mess around with it.

Would you like to use it or brag about it? Because you see - when I start the car, the radio comes on. And I don't care whether it's a smart or an ordinary relay, the important thing is that it turns on, which means it works.

Soon it will be smart cisterns that analyse how much of what is in the bowl and a microprocessor will calculate the amount of water needed to flush it heh.

There are already such flush toilets . As well as toilet seats that "talk" to them,and even serve music depending on the mood of the bottom.

And the toilet probably distinguishes and analyses whether Mr Dot or his wife has sat down. I have nothing against amenities. But many are simply an embarrassment.

Exactly so,Sedes analyses. My wife used to work for a company that designs and distributes this.
She'll rinse the back of it,remember the water temperature,sing it,dry it and even illuminate it.
You're right,it's embarrassing.

After a certain limit, the house can already become so intelligent that it considers the owner to be dumber than it is and does not let him in.

Flat block or detached house ? As a general rule, forced mechanical ventilation is not allowed in blocks/apartments .

A friend installed such a fan. The effect was that it was blowing half the night. In the morning he went into the bathroom and did a triple flip on wet tiles. Somehow when there was gravity ventilation for 50 years there were no problems.

I do not understand why the working fan could cause moisture in the bathroom tiles?

Because the ventilation shafts in a block of flats are shared.If you pressurise the chimney, your neighbour loses his ventilation.
You will make him fungus,or even poison him by injecting various gases.

Yes, that's right. In a block of flats, if someone has designed gravity ventilation, then switching on a fan in one flat can throw excess air at a neighbour. I don't know if it's so bad that the dampness comes through, but it's a fact that you generally shouldn't do that.
I live in a house so I don't have a problem.
Ok, thanks for the answers. I'm going to install a regular fan in the toilet with a delayed shut-off, in the bathroom I'll probably play with something.... maybe overkill but the word "play" is key here .
