Best Smart Pool Monitoring Systems

Keeping Your Pool in Top Shape Without the Guesswork

Owning a pool is awesome—until you realise how much effort goes into keeping it clean, balanced, and safe for swimming. Checking chlorine and pH levels, adding chemicals, and making sure the water’s not turning into a green swamp? It’s a bit of a hassle. That’s where smart pool monitoring systems come in.

Instead of spending time manually testing your water, these gadgets do the hard work for you, constantly tracking things like pH levels, chlorine, and temperature. They send the data straight to an app on your phone, so you know exactly when (and what) needs adjusting. No more guessing, no more wasted chemicals—just clear, balanced water, all the time.

What to Look for in a Smart Pool Monitoring System

Here’s what matters when choosing the right one:

Real-Time Monitoring – You want a system that gives live updates on your pool’s condition. Some devices check every few minutes, while others might update every few hours.
Clear App Interface – If the app is clunky or confusing, it’s pointless. You’ll want something easy to understand with simple recommendations on what to do next.
Chemical Level Tracking – Look for a system that measures pH, chlorine (or salt levels, if you’ve got a saltwater pool), alkalinity, and maybe even other things like calcium or cyanuric acid.
Temperature Monitoring – Not essential, but handy for checking whether your pool’s warm enough for a swim without sticking a toe in first.
Alerts & Advice – Some devices just tell you the numbers, while others will actually give advice, like “Add 2 cups of chlorine.” The smarter, the better.
Integration with Pool Equipment – Some systems can link up with pumps, heaters, and chlorinators to adjust things automatically. Super convenient if you want a fully hands-off experience.

Do You Actually Need One?

If you’re the type who enjoys testing your pool water with strips or kits—and you’re good at keeping everything balanced—then maybe not. But if you’d rather not stress about it, a smart pool monitor can save you time and money. It helps prevent over-chlorinating (which harms your skin and pool surfaces) or under-chlorinating (hello, green pool). Plus, if you rent out a holiday home with a pool, you can keep an eye on water quality from anywhere.

Setting It Up Is Easy

Most of these devices work straight out of the box. You just:

Charge it up (or pop in batteries).
Drop it into the pool or install it in the skimmer.
Connect to the app and follow the setup steps.

That’s it—no complicated wiring or installations needed.
