Contact, motion and light share the body, two AAA cells are rated for 3 years, Home Assistant is direct, and it is the more affordable and better reviewed. Alexa, Google Home, SmartThings, Apple Home and Matter need a SwitchBot hub. The Eve Door & Window is the Matter over Thread contact sensor that does not need that hub: Apple Home, Google Home, Alexa, SmartThings and Home Assistant are supported once a border router is present, on a half-AA cell rated for 11 months. It does not sense motion or light. Neither is weather resistant. Choose the SwitchBot Contact Sensor when the apartment door should also see motion. Choose the Eve Door & Window when Matter, with no SwitchBot hub, is the point.

What the differences mean

Motion or Matter without a brand hub

The SwitchBot Contact Sensor adds motion and light. Those automations, plus Alexa and Matter, need a SwitchBot hub. The Eve Door & Window is contact only, but Matter, Apple Home, Google Home, Alexa, SmartThings and Home Assistant do not need a SwitchBot or Eve hub. They need a Thread border router. An apartment that already has an Apple TV is closer to the Eve. An apartment that wants motion is closer to the SwitchBot.

Battery

The SwitchBot Contact Sensor is rated for 3 years on two AAA cells. The Eve Door & Window is rated for 11 months on one half-AA cell. On an apartment entry you would rather not open, the published SwitchBot life is the longer one. A low-battery alert is not published for either.

Size

The Eve Door & Window measures 52 x 24 x 23 mm, with an 18 mm magnet. The SwitchBot Contact Sensor measures 70.5 x 25.5 x 23 mm and weighs 43 g, with a 35 mm magnet. The Eve is the shorter body. Owners still call it chunky on inset doors because of the risers. Weight is not published for the Eve.

Weather

Neither sensor is weather resistant. An apartment entry on the indoor face of the door is in range for both. A balcony gate in the rain is not. The SwitchBot is the more affordable and the better reviewed. The Eve is the one that stays on Thread without a SwitchBot account.

Which one to buy if

What owners say

Owners of the SwitchBot Contact Sensor describe near-instant door alerts and a three-in-one they use for cabinets and garages, and they are clear that Bluetooth alone is not remote monitoring. Owners of the Eve Door & Window describe reliability on Thread, a sensor that can sit in Apple Home and Home Assistant at once, and updates that install themselves. They accept a higher price and a border router, and a few mention early Matter quirks or a body that needs risers on a sliding door.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
