It is rated for about five years on a CR2477 against about two years on the Aqara's CR2032, lists Google Home support without a brand hub, and accepts an optional sensing cable to reach a drip away from the puck. The Aqara Water Leak Sensor T1 answers with the better owner rating and a smaller, lighter body at 50 x 50 x 15 mm and 18 g, and it reaches Apple HomeKit and Matter through an Aqara hub just as the Sonoff reaches them through a SONOFF hub. Either way a Zigbee coordinator is required. Choose the Sonoff Zigbee Water Leak Sensor for the longest battery life and Google Home without an extra brand hub; choose the Aqara Water Leak Sensor T1 if you already run an Aqara hub or want the smaller sensor.

What the differences mean

Battery life

The Sonoff Zigbee Water Leak Sensor is rated for about five years on a single CR2477, against roughly two years on a CR2032 for the Aqara Water Leak Sensor T1. Behind an appliance, that is years less attention for the Sonoff.

Sensing cable option

The Sonoff Zigbee Water Leak Sensor can take an optional sensing cable to reach a drip away from the puck. The Aqara Water Leak Sensor T1 ships with no probe and detects water only where it sits.

Size and weight

The Aqara Water Leak Sensor T1 is the smaller and lighter of the two at 50 x 50 x 15 mm and 18 g, against 48 x 48 x 21.6 mm and 45 g on the Sonoff Zigbee Water Leak Sensor.

Google Home without a hub step

The Sonoff Zigbee Water Leak Sensor lists Google Home support, while the Aqara Water Leak Sensor T1 reaches Google Home only through an Aqara hub. Both still need a Zigbee coordinator for the sensor itself.

Which one to buy if

What owners say

Sonoff Zigbee Water Leak Sensor owners describe fast, reliable pairing with Home Assistant and Hubitat and automations that fire right away, including one buyer closing a shutoff valve on a leak. They like the waterproof, tool-free battery compartment and the low price that makes fitting several sensors easy, with low battery alerts to back it up. The friction they report is Samsung SmartThings, where several had to force-pair the device manually and one could not get it recognized at all. A couple also note the CR2477 is a less common cell to source, and with no on-device sound or light the warning depends entirely on the hub.

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.
