The battery can run more than 5 years. You can search on YouTube video of how to change the YoLink water sensor's battery and can find the videos. Thanks! **Q: Is this a dumb proprietary system or does it ingrate with smart home technologies, ie Z-wave Zigbee etc?** A: It is not Zigbee, WiFi or Z-Wave wireless technologies, all these wireless technologies only work for short range. The YoLink system use the longest wireless range and lower power consumption. It works with the YoLink hub and can be integrate to other system through the Alexa routines, IFTTT or YoLink's API. Thanks! **Q: Do you have any water leak sensors that have audio as well as the app reminder? Or are these just app reminders?** A: These 3 pack leak sensors don't have build in audio sound. We have YoLink water leak sensor 2 which has build in sound, both them have app push notifications, emails and text message for leak alert. **Q: What frimware version do you have on these D or E? Tx** A: Mine came with 030E installed. The sensors I bought previously had 030D installed and still aren't being offered the 030E update even though they are the exact same model number. I also don't know the difference between 030D and 030E as they don't seem to publish any firmware changelog that I can find. ## Frequently Bought Together - YoLink Water Leak Sensor 3-Pack, LoRa Up to 1/4 Mile Open-Air Range Smart Water Leak & Flood Detector, SMS/Text, Email & Push Notifications, w/Alexa, IFTTT, Home Assistant - YoLink Hub Required - YoLink Smart Home Starter Kit: Hub & Water Leak Sensor 4-Pack, SMS/Text, Email & Push Notifications, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT, Home Assistant - YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range for Fridge, Green House, Pet Cage, App Alerts, Emails, Text/SMS alerts- Hub Required --- ## 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.ph/products/185757315-yolink-water-leak-sensor-1-3-pack-ys7903](https://www.desertcart.ph/products/185757315-yolink-water-leak-sensor-1-3-pack-ys7903) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-11-06*
