YoSmart YS1603+2YS7903 Smart Home Starter Kit: Hub & Water Leak Sensors: LoRa technology for extreme long range
Here's why you'll love it:
- Setup? A breeze. Just plug it into your router's ethernet port, and you're pretty much done. It's that easy.
- Range that impresses. We're talking up to 1/4 mile in open air. Basements, sheds, even that weird little house out back – covered.
- Notifications that don't quit. Even if your WiFi throws a tantrum or the power goes out, you'll still get SMS, email, and push alerts. Because peace of mind shouldn't take a day off.
- Plays well with others. Alexa, IFTTT, Home Assistant – it's like the social butterfly of smart home gadgets.
Batteries are included (because we're not monsters), and setting it up is as simple as putting the sensors where leaks might happen. If you're into smart homes, this kit's basically your new best friend.
