Buy on Amazon USA

The Arlo All-in-One Sensor wins this water leak sensor comparison with leak, temperature, and tilt plus Google Home, Alexa, and SmartThings, inside an Arlo Security System. The Centralite 3-Series Water Sensor is the more affordable Zigbee-only option, with fuller freeze and low-battery alerts on SmartThings and Home Assistant, but no tilt and no Google or Alexa. Neither has a local siren. Choose the Arlo All-in-One Sensor if Arlo is already the backbone; choose the Centralite 3-Series Water Sensor for a cheap dedicated Zigbee leak-and-freeze disc.
