What the differences mean

Zigbee hub versus Wi-Fi

The Aeotec Water Leak Sensor needs a Zigbee hub and lists no Wi-Fi or Bluetooth. The SwitchBot Water Leak Detector lists 2.4 GHz Wi-Fi and Bluetooth and no extra hub. They share SmartThings and Home Assistant only if you count different paths: Zigbee for Aeotec, Wi-Fi for SwitchBot.

Siren versus freeze alerts

The SwitchBot Water Leak Detector lists a sound and a light and no temperature or freeze alerts. Contacts are described on the top and the bottom. The Aeotec Water Leak Sensor lists a temperature sensor, temperature alerts and freeze alerts, and no sound or light. Neither includes a sensor cable, so placement is the whole detection story for both.

Platforms

The SwitchBot Water Leak Detector lists Google Home, Apple Home, SmartThings and Home Assistant. Alexa and Matter are unsupported. The Aeotec Water Leak Sensor lists SmartThings and Home Assistant only. Google Home, Apple Home, Alexa and Matter are unsupported. Both list automations and water-leak alerts.

Housing and battery

The SwitchBot Water Leak Detector is IP67 and quotes about two years on two AAA cells, at 109 g. The Aeotec Water Leak Sensor is IP20 and quotes about one year on a CR2, at 47 g. Low-battery alerts are not documented on either. Warranties are one year on both.

Which one to buy if

What owners say

Owners of the Aeotec Water Leak Sensor and the SwitchBot Water Leak Detector both describe a reaction within seconds of water hitting the contacts, and both have used that alert to avoid a bigger mess. Aeotec Water Leak Sensor owners single out build quality, SmartThings or Home Assistant pairing, and freeze alerts, and they complain about IP20 placement, a costly CR2 and no sound or light on the puck. SwitchBot Water Leak Detector owners single out a few minutes from unboxing to Wi-Fi with no hub, and sensitivity on a small amount of water, and they warn that the body has to sit in the puddle because there is no cable, and that the siren is loud up close and easy to miss from another floor.
