Which sensors for what? Inspiration

Yes, I have already communicated with you about that. That is exactly what I just described. You can then distinguish between open/closed or tilted.

Oh, I somehow overlooked that. Sorry. Sounds good though! Thank you.

But that only works if you explicitly order [Verschlussüberwachung]. If you simply order two contacts and open/closed/tilted, then precisely your concern may come true and you could lock yourself out.

With us, the reed switches on the window are only closed when the window is also closed. That means if you only pull the window (from outside) close, it is still open for the reed switch.

Closed or locked?

But that only works if you explicitly order lock monitoring. If you just order two contacts and open/closed/tilted, then your exact concern can unfortunately come true and you can lock yourself out.

Unfortunately, the thought only occurred to me now, the windows are of course already ordered. *facepalm*
Unfortunately, I can only see "Aerocontrol" in the order. They are all described as lock monitoring by Siegenia. As far as I understand it, if you look at the devices from the manufacturer, it apparently depends on where they are installed in the frame.

Assuming it’s as I fear, can I give a binary input for the reed a blocking function? Maybe via a button or something?

Closed or LOCKed?

Locked -> Reed closes the contacts
