It also runs on two AAA batteries for about 2 years, so it goes anywhere, and connects over Wi-Fi or Bluetooth with no hub, with an IP67 rating. The Eve Water Guard is built for Apple Home: it joins over Thread or Bluetooth, plugs into the wall so there are no batteries to replace, and its sensing cable can be extended to cover a whole run of appliances. Home Assistant works with both, and neither supports Alexa or Matter today. Choose the Switchbot Water Leak Detector (Sensor Cable Edition) for a mixed-platform home or a spot far from an outlet, and the Eve Water Guard for an Apple Home and Thread setup that wants one sensor along a kitchen or laundry wall.

What the differences mean

Platforms

The Switchbot Water Leak Detector (Sensor Cable Edition) works with Google Home, Apple Home, SmartThings and Home Assistant. The Eve Water Guard works with Apple Home and Home Assistant, with Matter announced but not yet available.

Power

The Eve Water Guard needs a wall outlet and has no battery to change. The Switchbot runs about 2 years on AAA cells and can sit anywhere.

Coverage

The Eve cable senses along its whole length and can be extended, so one unit watches a long run of appliances. The Switchbot detects at its body and at the cable tip, two points from one sensor.

Connection

The Eve Water Guard uses Thread, which needs a Thread border router in the home, or Bluetooth. The Switchbot connects to 2.4 GHz Wi-Fi or Bluetooth.

What owners say

Owners of both describe fast, dependable detection and use the cable to reach places a puck cannot. Eve Water Guard owners single out setup by scanning a code straight into the Home app with no account, the siren and light firing alongside notifications, and one sensor covering a full appliance run; they note the price, the need for an outlet and a fabric cable that has to soak up a little water first. Switchbot Water Leak Detector (Sensor Cable Edition) owners talk about connecting without a hub in minutes and watching two spots at once, the body and the cable tip, such as a water heater pan. Their complaints are a stiff battery hatch whose pry tool breaks, an alarm that is hard to hear through cabinet doors and an app cluttered with prompts.
