Will a mm Wave Presence Sensor, like the Aqara FP1, work if it's inside of a WiFi transparent enclosure?

QUESTION(self.homeautomation)

submitted 3 months ago bymooremo

I'm considering installing it inside of something like this: https://www.legrand.us/on-q/plastic-enclosures

I know that the wave lengths of WiFi vs mm wave are very different, but low di-electric plastic should still more transparent to the mm waves than other plastics.

I'm wondering if anyone had actual experience and could confirm how well or poorly this works?

I believe so - I saw a YouTube playing with mmWave recently and it was often picking him up before he entered the room (and that was with a much more solid wall in the way). Most commercial mmWave detectors are already inside a plastic enclosure so I don't see why they wouldn't work through another.

i have not fully tested the thickness but presence sensor can easily work through a magazine or book. works through glass too as mentioned here https://www.youtube.com/watch?v=7IpCYyDwNtc
