Paired without issue. ### ⭐⭐⭐⭐⭐ Easy setup, excellent product. *by A***Z on January 14, 2026* 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! ### ⭐⭐⭐⭐⭐ Works great, easy connect to base unit. Wish I had gotten it two months ago! *by L***E on March 8, 2025* We got this Eufy Security Water and Freeze Sensor with Remote Alerts, to add to our Eufy system base unit. Easy to follow directions to set up. Leak detection should be excellent as it detected even a little water on the test runs. The only problem we had connecting was due to the network password being changed (our error). I'm super glad we got this and it gives me peace of mind that we can deal with any future leaks where this Eufy sensor is placed. And yes, we got it AFTER we had a leak, fixed the faucet, and cleaned up the mess. ## Frequently Bought Together - eufy Security Water and Freeze Sensor with Remote Alerts, IP65 Waterproof, 2-Year Battery Life, HomeBase Required, Compatible with HomeBase 2 and 3, Optional 24/7 Protection Service, App Control - eufy Security Entry Sensor, Detects Opened and Closed Doors or Windows, Door Monitoring, Sends Alerts, Triggers Siren, 2-Year Battery Life, Indoor Use Only, Requires HomeBase, 24/7 Monitoring Optional - eufy Security HomeBase S380 (HomeBase 3),eufy Edge Security Center, Local Expandable Storage up to 16TB, eufy Security Product Compatibility, Advanced Encryption,2.4 GHz Wi-Fi, No Monthly Fee --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/589876267-eufy-security-water-and-freeze-sensor-with-remote-alerts-ip65](https://www.desertcart.co.uk/products/589876267-eufy-security-water-and-freeze-sensor-with-remote-alerts-ip65) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
