Review: For someone who lives in an area where basements flood in the winter, this product provides the peace of mind I need. Setting up was very easy, just putting in the provided battery and going through the steps in the app to connect it to my homebase. Through some testing I did, even the smallest drop of water will instantly send a message to my phone alerting me that water has been detected. As someone who travels a lot for work, it's nice to know I won't be unknowingly coming back to a flooded house.

Exactly what was needed. Scan the QR code on the item, goes right into the eufy app. So easy. Couple drops of water set it off. You can get alert messages on your phone, the siren on the hub, or both. Great product!
