We are planning our smart home in the single-family house

For measuring a TV, I can only recommend active power measurement. I have done current measurement, and it is not very enjoyable. I am already close to reworking it.

However, I noticed that during planning, the costs were taken too lightly. Now, in hindsight, you look more closely whether to spend another €300 on an actuator. It simply doesn't get lost in the larger sum anymore.

Maybe you can "monitor" the TV via the socket but also leave it out and simply query it directly via an API?!

Of course active power. I have not installed anything else anywhere.

Or use a Visu/Server that can directly control the TV (and the rest of the AV equipment) and capture its status.

Forgotten shoes in the hallway have long ceased to be an obstacle for my robot vacuum. It reliably recognizes them and drives around them.

Shoes themselves are not a problem, but shoelaces get sucked in. So if one is not disciplined enough and does not always keep everything out of the vacuum’s reach, the automation doesn’t work.

For all other things, you go with the latest standard, but for the electrical system you are planning according to the 1950s standard?
To me, that’s like controlled residential ventilation – sure, I could ventilate myself.
But I don’t have to anymore.

The comparison is way off. KNX has nothing to do with the current standard for electrical installations. The current standard is more about complying with current regulations, installing more sockets than before + possibly preparing for a wallbox.

To keep the comparison going: Then I just won’t buy a car from a company that doesn’t even have a high beam assistant. And if the car has rust everywhere because no attention was paid when buying it, it’s certainly not the high beam assistant’s fault.

It’s really funny how KNX advocates feel attacked when you don’t share their opinion.

I’m not fundamentally against it, but I don’t understand how people try to automate things at all costs where costs and benefits are not in proportion. I still understand light control. Temperature sensors to monitor fridges and freezers also make sense. Heating control in new buildings is more of a gimmick. If heating costs are already low, it doesn’t make any sense to invest three- or four-digit amounts to “save” a few euros.

How is it supposed to work to turn on the towel radiator early enough during a shower so that the towel is really warm? That only works by switching it on based on time. Presence detection doesn’t make sense since you visit the bathroom more than once a day. If several people need to shower in the morning, you can’t exactly stand in the shower for 15 minutes waiting for the towel to get warm.

Lowering the blinds when the TV is on? That only makes sense if you’d really be blinded. So it’s not only about time and general weather, but also the exact position of the sun including cloud coverage. Otherwise, you’re sitting in the dark as soon as the TV turns on. Fantastic :rolleyes:
Better to have a sun sensor that generally controls the function of the blinds to prevent it from getting too warm.

For many of the listed functions, there are either solutions from the respective manufacturers that are much easier to set up, or they can be implemented with manageable effort without wiring the whole house.

Here in the forum, you often read that people plan using KNX and what amazing things you can do with it.
However, so far I haven’t read about what has actually been implemented and works in practice. I’d really be interested in a real experience report.

There are simply people who have no desire for it and certainly no creativity to come up with scenarios for it. They just don’t need it. Then there are others who enjoy it and delight in the increased comfort. Just because you don’t know any good smart home projects doesn’t mean anything at all. It’s not your dance floor – absolutely OK. But please don’t start trying to take away others’ fun by claiming that a collection of isolated systems would deliver the same good result. I’m not just a fanboy in this area; I’m also on the contractor side. So I’m certainly not neutral on the topic, but I really know some projects that are a lot of fun.

How is it supposed to work to switch on the towel radiator early enough when showering so that the towel is actually warm? That only works with switching on according to time. Presence detection makes no sense, since you visit the bathroom more than once a day. If several people have to shower in the morning, you can’t stand in the shower for 15 minutes waiting until the towel finally gets warm.

A prime example. Just because you have no idea how to do something like that, it doesn’t exist in your world. Horizon with radius zero and that’s the standpoint.

No offense, but if you have absolutely nothing constructive to contribute, you can simply stay out of a thread of someone interested in it.

How is it supposed to work to turn on the towel radiator early enough while showering so that the towel is actually warm?

Now you really made me laugh. You’re also the first person to explain to me that the thing is supposed to preheat a towel... I use it more for drying towels or to warm the bathroom more than the underfloor heating manages. But yes, where is the problem to combine time, presence in the house, temperatures, and occupancy? That’s a one-time job, then it just runs.

Lowering the blinds when the TV is on? That only makes sense if you would really be blinded. So it’s not only the time and general weather that have to be considered, but also the exact position of the sun including cloud cover. Otherwise you sit in the dark as soon as the TV is turned on. Great :rolleyes:

Yes, and what else? There is a weather station with brightness sensors for that. The data is all available on the bus anyway. Combine it with a bit of logic, done. You might find that “great,” but honestly, this is one of the most beneficial comfort features I use. Typically, you would have skipped the window here precisely because it would constantly cause glare. This way I have regular daylight and when the TV is on, nothing blinds me. It works just as well in the living room as in the children’s rooms, which by the way also love this feature. Besides, just because one single glare-free lowered blind is in use, you don’t suddenly sit “in the dark.”
