It needs the Ring base station, uses Z-Wave, adds tamper detection, and runs up to 3 years on two CR2032 cells. It works with Alexa and Home Assistant, and it is the more affordable and better reviewed of the pair. Google Home, Apple Home and Matter are not supported. The Eve Door & Window brings Matter over Thread to that same front door, with Apple Home, Google Home, Alexa, SmartThings and Home Assistant, and no Ring base, but it needs a Thread border router and its half-AA cell is rated for 11 months. Fit the Ring sensor when the entry is already on Ring Alarm. Fit the Eve Door & Window when that door should live in Apple Home.

What the differences mean

Alarm base or border router

The Ring Window and Door Contact Sensor (2nd gen) only works with a Ring Alarm base station, over Z-Wave. The Eve Door & Window only works with a Thread border router, then joins Matter. A front door with neither box in the house cannot use either sensor as it ships.

Tamper alert

The Ring Window and Door Contact Sensor (2nd gen) includes tamper detection, which owners meet when a metal or uneven frame holds the sensor in a tampered state. A tamper alert is not published for the Eve Door & Window. That is an unknown, not a documented missing switch.

Platforms

The Eve Door & Window supports Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Matter. The Ring Window and Door Contact Sensor (2nd gen) supports Alexa and Home Assistant only. Google Home, Apple Home, SmartThings and Matter are not supported on the Ring sensor.

Battery and shape

The Ring sensor uses two CR2032 cells rated for 3 years, in a 53 x 28 x 14 mm body. The Eve Door & Window uses one half-AA cell rated for 11 months, in a 52 x 24 x 23 mm body. The Ring piece is the slimmer one on a flat frame. The Eve needs more depth.

Which one to buy if

What owners say

Owners of the Ring Window and Door Contact Sensor (2nd gen) praise a peel-and-stick install, phone alerts that arrive as the door opens, a slim body and cells that last a long time, and they like the screw-down cover on the newest units. They complain that a metal or curved frame can stick the sensor in a tampered state, that the included adhesive is weak, and that the sensor does nothing without a Ring Alarm base. Owners of the Eve Door & Window, often coming from sensors that fell off the network, call this one the unit that stays connected, with an easy iPhone setup. They note the higher cost, the border router requirement, and risers that are fiddly on a sliding door.
