SwitchBot Presence Sensor 2pack

Set them up in my living room and the mmWave radar catches me even when I’m sitting perfectly still reading, which is exactly what I needed. The light sensor also stops false triggers during the day, so it’s been rock solid for three weeks now.

I was skeptical about the PIR sensor missing me when I'm sitting perfectly still on the couch, but the mmWave radar caught my subtle chest movements right away. Even with just the 2pack, I've got coverage in both the living room and office without any false triggers from passing cars outside.

The mmWave radar picks up on the tiniest movements, even when I’m sitting perfectly still reading. It’s been flawless at distinguishing between me actually being in the room versus just walking by, which is exactly what I needed for my automation setup.
