It works with Google Home, SmartThings and Home Assistant, reaches Apple Home and Matter through a SONOFF hub, and is rated for 5 years on its CR2477 cell against 2 for the Eufy. The Eufy Water and Freeze Sensor has what the Sonoff lacks, a temperature sensor with freeze alerts, but it only works through a Eufy HomeBase and with Home Assistant. Neither has a siren or light on the sensor. Choose the Sonoff Zigbee Water Leak Sensor for a Zigbee hub or Home Assistant setup, and the Eufy Water and Freeze Sensor if you already own a HomeBase and want freeze warnings next to your cameras.

What the differences mean

Which hub it needs

The Sonoff Zigbee Water Leak Sensor works with any compatible Zigbee hub, from Home Assistant and Hubitat to SmartThings. The Eufy Water and Freeze Sensor only works through a Eufy HomeBase, the base station of Eufy's security cameras.

Smart home platforms

The Sonoff Zigbee Water Leak Sensor works with Google Home, SmartThings and Home Assistant, and with Apple Home and Matter through a SONOFF hub. The Eufy Water and Freeze Sensor works with Home Assistant and no other platform.

Freeze alerts

The Eufy Water and Freeze Sensor measures temperature and warns before pipes freeze. The Sonoff Zigbee Water Leak Sensor detects water only.

Battery life

The Sonoff Zigbee Water Leak Sensor is rated for 5 years on a CR2477 cell, a size some owners find harder to buy. The Eufy Water and Freeze Sensor is rated for 2 years on a CR123 cell.

Water protection

The Sonoff Zigbee Water Leak Sensor is IP67 and can sit in water. Eufy does not publish a rating for the Water and Freeze Sensor.

Which one to buy if

What owners say

Owners of both describe sensitive detection and easy pairing into the system they already run. Sonoff Zigbee Water Leak Sensor owners, mostly on Home Assistant and Hubitat, single out pairing done in a minute or two, automations that close a shutoff valve and a gasket-sealed, tool-free battery door. Eufy Water and Freeze Sensor owners single out QR-code pairing into a HomeBase and alerts that arrive both on the phone and as a HomeBase alarm. The complaints differ: Sonoff owners mention SmartThings pairing that needed a workaround, reliance on the hub for any alert and a less common battery size, while Eufy owners mention a HomeBase alarm that sounds like a break-in, occasional pairing failures and a recording schedule that can hold back alerts.

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.
