YoLink Smart Home Starter Kit: Hub & 4 Water Leak Sensors with LoRa Technology
🚀 Unlock Your Smart Home with the YoLink Smart Home Starter Kit. Imagine never having to worry about water damage again—this kit's got your back with a hub and four leak sensors that scream (figuratively, of course) at the first sign of trouble, sending alerts straight to your phone, email, or wherever you'll actually notice them.
🔍 Features:
- Thanks to LoRa Technology, this thing can practically send signals from the moon (okay, maybe just 1/4 mile in open air). Basements, sheds, even that weird little garden house you never use? Covered.
- Setup is a breeze—seriously, it's almost too easy. Just plug it into your router's ethernet port, and boom, you're in business. No tech degree required.
- Plays nice with Alexa, IFTTT, and Home Assistant, so it'll fit right into your existing smart home like it was always there.
- Stick these sensors near anything that holds water (toilets, water heaters, laundry machines—you get the idea) and sleep soundly knowing you'll be the first to know if something's amiss.
💡 Heads up: You'll need a YoLink Hub to get this gadget online. It's a bit old-school—no direct WiFi or local network connections here.
