Again, presence simulation might be a nice psychological sales trick used by manufacturers, but it is not an effective security measure. Even a casual intruder wouldn’t be deterred by something that simplistic. It also seems common for many to just ring the doorbell first and pretend to be Jehovah’s Witnesses, etc., if someone answers. Burglar-resistant windows are what actually help against break-ins. Nothing else.
For example, in our apartment, we have three windows in the living room with internal blinds, and there is simply no way to automate these blinds mathematically. Sometimes I want one area dark while the other two remain open. Sometimes the middle blind is lowered to prevent glare on the TV, but the other two stay open. When the TV is off, the middle blind doesn’t bother us either. Or with only moderate sunlight. Or at a different time of day, a different blind is adjusted. Sometimes a different blind is lowered because someone is playing on the floor there. Depending on whether we feel cold or warm, direct sunlight is either welcome or unwanted. This can even be pleasant in winter, but sometimes, even in February, it can be far too glaring.
If you only want to lower them in the evening and raise them in the morning, that can be automated. In our case, however, the position of the blinds depends on numerous factors that cannot be technically measured. Of course, this might change in a house, but I doubt it.
Therefore, it would hardly be possible for us to automate anything sensibly. But if it’s just about raising them in the morning and lowering them in the evening, that works without any problems. If that is the only requirement, then I would probably automate it too.
Sun and wind sensors, of course, are installed on the external roller shutters. That should be mandatory. We will probably also install a window contact on the terrace window’s roller shutter. But complete automation from A to Z seems too complicated for constant reprogramming and rethinking. Things never stay the same anyway.

There are people with a mostly panic-driven fear even in our new housing development. The amount invested in security technology is quite something... well, if someone needs it, they should go ahead and do it.
By the way, I prefer conventional switches on the windows 😉 plus automation that covers 90% of cases (whether KNX, Homematic, wired or wireless, etc.). The remaining 10% of situations are usually those where you’re standing right in front of the window rather than at a central location like a living room door. And then having to grab my phone and fiddle around with some app... no thanks.

Attitudes change as soon as the first houses in the neighborhood are cleared out... A simple presence simulation, like the one Grym described, is hardly effective. You really need devices that can do more than just turn lights on/off and raise/lower blinds.
Even a simulated barking dog or TV simulation using the well-known LED spotlight from East Asia are more toys and mostly just deter teenagers.
The security concept should be well thought out... similar to home automation... the idea that more is always better is wrong in both cases.
Of course, presence simulation does little against professional burglary gangs, but it does deter opportunistic thieves.
Lighting is just as powerful a tool, and simply having it can scare off some intruders because the risk of being detected increases exponentially.
