Aqara Water Leak Sensor vs Shelly Flood (2026)

Updated June 2026

Data from Amazon and official Aqara and Shelly sites.

2026 verdict

Winner

$24.99

The Shelly Flood is the better all-rounder in this water leak sensor comparison, taking the win on a longer 2-year warranty, more integrations, and extra sensing, since it adds a temperature sensor with freeze and temperature alerts and connects directly over Wi-Fi to Google Home, Alexa, SmartThings and Home Assistant with no hub needed. The Aqara Water Leak Sensor counters with solid value credentials: a lower price, a higher owner rating, an IP67 rating where the Shelly lists none, and a slightly longer 2-year battery versus the Shelly's roughly 1.5 years on a cell you buy separately. Neither has an onboard siren. Pick the Shelly Flood for hub-free Wi-Fi leak and temperature detection across more platforms; choose the Aqara Water Leak Sensor for a cheaper, higher-rated, IP67-waterproof Zigbee sensor that pairs with HomeKit or Home Assistant.
