Ever worried about coming home to a swimming pool where your living room should be? The YoLink LoRa Smart Water Leak Protection System is here to save the day (and your floors). This isn't just any leak detector—it's like having a vigilant, tech-savvy guardian for your home. With its advanced detection and automatic shut-off, it's basically the superhero of water leak systems. And guess what? It comes with a stainless steel motorized valve that's as tough as nails, three leak sensors that don't miss a trick, and a hub that plugs into your home network smoother than your favorite playlist.

- First off, the LoRa technology is a game-changer—think of it as sending texts between devices over a quarter-mile, no 'message failed' here.
- Running on batteries that last up to 3 years? That's right, power outages can take a hike.
- It plays nice with Alexa, Google Assistant, IFTTT, and Home Assistant, so you can boss it around from your couch.

LoRa Smart Water Leak Protection System

i bought this because we had a small leak in the basement last year that caused some damage, and i wanted a solution to prevent that. the system works okay—it shut off the water when i tested it with a spill, which is good. but overall, it's not as reliable as i expected. the problem was finding something easy to use, and while this helps, it's not perfect. the takeaway is that it's a decent guard but has flaws, so i might look for something better in the future. not super happy with it.
- Pros: it does stop water leaks automatically, which is a relief, and the sensors seem to pick up moisture pretty well. i like that it works without the internet sometimes, and the battery life is super long, so i don't have to fuss with it often. setup was easy enough for me to handle on my own, and it connects to my smart home stuff, which is handy.
- Cons: from what i feel, the manuals are useless and confusing, making it hard to figure out some parts. it didn't come with all the fittings i needed, so i had to buy extra, which was annoying. the range isn't as good as i hoped, and it sometimes misses small leaks. i'm disappointed that it doesn't integrate smoothly with all my devices, and the cloud service feels unreliable at times.
