The sensors are housed at the bottom of the unit, this is where all the readings are measured. From here all data is electronically transmitted via wifi/Bluetooth to the app in real time. Specifically designed to fit all shapes and types of pools. inground, above ground, plunge pools or even spas. All units are also compatible with Chlorine, bromine and salt water chlorination.

The thermometer itself has a large float on the top of it, which keeps it at the surface of the water. This is the part of your pool where the temperature can vary the most, so by keeping it just below the surface you’re able to get the most accurate reading.

The mobile app (for Android and iOS) lets you check chemical levels at a glance (in real time!) and can also enable push notifications when it's time to check and adjust required levels. Simply tap the action required notification and follow the directions.

A “heads up” display on the home screen easily reads the key measurable providing an easy, no-nonsense indication to the condition of your pool.

Data artificial intelligence also stores and records trending data, this allows for trackable history of readings, and even forecasting of what to expect for the period ahead.

Our professional opinion of this new technology and what's to come?

According to some of the manufacturers, the unit itself only has a lifespan of 18-24 months before it will have to be replaced due to battery and or sensor wear.

Some models are based on a subscription service, meaning if you don't subscribe, many of the app features may be lost but you'll still receive temperature and basic alerts when chemical levels are skewed, but you'll no longer receive dosage recommendations, trends or push notifications, and when its battery and internal sensors die (which they will), you're out of luck.

The last thing you want to do this time of year is to fool around with your local pool shop and a range of chemicals sold to you in store that you don't really need.

Simply drop the monitor in your pool or spa, and let your mobile device tell you when to add chemicals. You'd much rather be in the pool enjoying the clear, cool clean refreshment of your watery backyard oasis.
