What the differences mean

Zigbee versus Z-Wave

The Sonoff Zigbee Water Leak Sensor needs a Zigbee hub. The Aeotec Water Sensor 7 Pro needs a Z-Wave hub. A search for an Aeotec Zigbee leak sensor does not match this Aeotec: the 7 Pro sheet lists Z-Wave only. The two will not share a coordinator.

Probe and freeze alerts

The Aeotec Water Sensor 7 Pro includes a sensor cable and lists temperature, temperature alerts and freeze alerts. The Sonoff Zigbee Water Leak Sensor does not include a cable, and its water-leak line mentions an optional sensing cable that is not the included accessory. It lists no temperature sensor and no freeze alert.

Platforms

Both list SmartThings, Home Assistant and automations. The Sonoff Zigbee Water Leak Sensor also lists Google Home, and Apple Home and Matter when a SONOFF hub is required. The Aeotec Water Sensor 7 Pro lists none of Google Home, Apple Home, Alexa or Matter. Alexa is unsupported on the Sonoff sheet too.

Housing and cells

The Sonoff Zigbee Water Leak Sensor is IP67, 48 x 48 x 21.6 mm and 45 g, and quotes about five years on a CR2477, with low-battery alerts. The Aeotec Water Sensor 7 Pro is IP20, a slim 70 x 20 x 13 mm probe-style body, about three years on an ER14250. Its low-battery alert is not documented. Neither has a sound or a light. Warranties are one year on both.

Which one to buy if

What owners say

Owners of the Aeotec Water Sensor 7 Pro and the Sonoff Zigbee Water Leak Sensor both use the sensor to start an automation, including a shutoff, and both note that the puck itself is silent. Aeotec Water Sensor 7 Pro owners single out sensitivity, the included probe in a pan or a crawl, and temperature plus freeze alerts, and they complain about a fussy Z-Wave pair and about probes that corroded when left wet. Sonoff Zigbee Water Leak Sensor owners single out pairing that finishes quickly on Home Assistant and Hubitat, an IP67 body with a tool-free battery door, and buying several at once, and they complain that SmartThings often needs a manual pair and that there is no sound, no light and no temperature sensor.

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.
