Eve Door & Window

Quick verdict

A contact sensor from a brand that prioritizes privacy. No cloud, no account, just Thread and Matter. It costs more than a cheap Zigbee sensor, but you get a clean setup experience and the confidence that your door open/close data stays on your network. Works great in both Apple Home and Home Assistant.

Standout: Privacy-first Thread contact sensor with zero cloud dependency.
