Smallest reliable door/window sensor?

I got a Niki 2thar has a door sensor. I love it and now want it on manY more doors incl interior ones.

My wife isn’t so Keen on the idea though. Mainly for estethic reasons.

So any recommendations for low key door sensors?

Maybe this? > https://aeotec.com/hidden-z-wave-door-sensor

Interesting! That does require me to drill a rather large hole in my doors. I can do that in a few places but no t all.

Any other non drilling low key sensors?

I’d recommend Xiaomi’s Aqara line of Products.

They’re using Zigbee Protocol, therefore you need to have a Zigbee Gateway.

I have a conbee for my lights. Would it work with that?

Thanks

Yes. Personally I never used Conbee, but other people reportedly confirmed it working with Xiaomi Aqara Sensors

I can confirm that Aqara door/window sensors work well with Conbee (no battery level reporting though), and they are surprisingly small.

I have a Sensative strip, running on z-wave, so you need a hub/dongle for that. The strip is not noticeable from the outside, and barely from the inside. They are quite expensive, though

Cool. At 8$ i couldn’t resist buying some

Oh those are nice. I’ll remember them for once get zwave enabled
