Hello everyone,
we are building a detached house with Allkauf Haus in Baden-Württemberg. This building company apparently has only one supplier for exterior doors and windows, who does not offer models with integrated contact sensors or insect screens. It also seems impossible to source windows and doors from a third-party supplier, as these are not allowed to be processed at the manufacturing facility, and without windows and doors the prefabricated elements for the house will not be delivered.
Therefore, I am currently looking for a wired solution to retrofit contact sensors on the outside windows and doors.
I only need simple status indicators: window open, window tilted, or door open. A simple reed switch that can later be read by my smart home system. Under no circumstances do I want a proprietary system or wireless transmission.
Do you have any ideas on how to retrofit wired sensors in new windows and doors? A manufacturer for this? Or an alternative idea?
Thank you and best regards
Chris

If in doubt, it’s proven helpful to call the manufacturer, play dumb, and simply ask whether it works with this or that window.
It’s also inconvenient. If the active part is attached to the frame, you can’t trigger a vibration alert.

But the window doesn’t exactly come with cables and built-in sensors, right? No, most likely not. But if the wall is open and you can access every window frame from three sides, installing, drilling, and connecting shouldn’t be a problem, right!?

It’s annoying though. If the active component is mounted on the frame, you can’t have a vibration warning. lastdrop schrieb:
Security concerns? nordanney schrieb:
Doesn’t help if the glass is just smashed... These sensors have nothing to do with burglary protection. They are only for status indication—whether a door or window is open or closed. Whether the kids left a window open... purely for convenience. No security aspect at all.

To me, this sounds a bit over-engineered. You’re building with Allkauf Haus; why pursue such a special solution? Is there a particular reason? nordanney schrieb:
Probably male playfulness—I can totally understand that. I am an engineer and have dealt with (home) automation for almost decades, so you get these kinds of wishes when building your own home.
BTT:
Do you know manufacturers of retrofit, integrated, invisible, wired state sensors for doors and windows?
That can be retrofitted on (almost) any window/door (manufacturer).

I have done this myself multiple times, at least 30 windows and 10 doors. If the window comes from the manufacturer already integrated with sensors, there is a cable coming out from one side of the frame. You put this cable into the conduit and extend it using a crimp connector. This works not only almost flawlessly, but always flawlessly.That’s clear, I did the same in my own home. But that was not the question, since the windows there are already factory pre-drilled, and the cables can be properly routed and sealed during window installation.
We planned a timber frame construction ourselves and are doing the drywall work on our own. Therefore, all walls are still empty (no insulation) and open at the time of window installation. I’m not worried at all about making the connections.OK, that’s a different situation. If you can access behind the window frame (more precisely you won’t, since you will have timber studs all around), then it’s relatively easy.
If you have no concerns about carefully drilling through the window frames and wooden beams, then it is, of course, quite simple.
Just use an installation contact switch, for example BSS 404042.x, drill the window frame (and if needed the timber stud only with the diameter for the cable) and the sash just as deep as the magnet length, then stick or screw on the parts (depending on the manufacturer). Provided you don’t want locking monitoring, this is all quite easy to retrofit.
Oh, one more thing: I’m not familiar with all window systems, so if there are differences, you should clarify with Allkauf Haus in advance what exactly you will be getting. If your casement window system has a locking mushroom head fitting at the bottom of the window that can be set in three different positions depending on closed/open/tilted, then you could install the two reed switches right there and evaluate the different states.
If not, you will probably need to install them at the top and bottom.
