Open window/door detection?

[Alan Ambrose]

Anyone found a nice solution to this, preferably hard-wired?

 

By 'nice', I mean not too ugly and a thought out install into the window/door frame...

 

I should say that I'm planning on external blinds and would like them to be smart enough to not come down when outward opening windows/doors are open.

Recessed magnetic contact sensor / reed switch as used in alarms - depends on your doors / windows, then just need someway to make that info available to your blinds

When I looked, the window/door companies seemed to offer this as an option on their products. I'm sure vastly overpriced for what is a magnet and a reed switch (cost <50p).

 

With planning I expect you could plan to retrofit something to windows doors just after they are installed but you would be putting holes in the frame and not sure how that affects warranties, etc. (though a common window install method holes in the frame as well so can't see it being a huge deal).

 

Not got far enough to think about this in more detail.

You could consider using one of these...

It is battery powered but supposed to last years and designed to sit unobtrusively in the edge of the door/frame. Uses zwave to communicate with a smart home capable of linking to zwave devices - such as Samsung SmartThings, Home Assistant or others. If using Smart Home control for the blinds they could be using the same hub and then could be nicely integrated that way.

 

When you say external blinds, do you mean shutters ?

PS There are also numerous other more chunky window/door sensors including zigbee or matter ones around (always battery but life shorter than the sensative in built battery)...

PPS Just remembered there is also this type if you can drill into the frame to fit it (a bit like a door latch barrel), such as wooden frames...

Speak to your window supplier, they should be able to factory install them as most supply reed contacts. You can have this connected to your smart home if required, wireless enabled etc. If they do not know what you are referencing, look elsewhere.

It immediately voids them, as the window has been altered. It does depend on the manufacturer, some won't mind but if it is the root cause, warranty is void.
