Working well. Monitoring hit tub water status from 700+ miles away!

Ordered the calibration kit to ensure everything was reading correctly before I started adding chemicals to open my pool for the year, super easy step by step instructions made it a breeze.

I received the Eco system last year as a present, and it work flawlessly all season. This spring I tried to wakeup the system and put it back in to service. But the Eco sensor would not stay connected. I contacted iopool with my issue. With in a day, they had reached back out to me with a couple things to try. iopool's also tried a couple things on there end, to no avail. The system was still under a warranty. Without hesitation, they sent me a new Eco sensor. Which I have up and running. My experience with customer service was great. I would recommend this system to anyone that has a pool.

Excellent monitor. East setup!

I left a message on the help center. I need someone to contact me.

Although it's only been a few days since I started using the Smart Water Monitor, I'm impressed. It was very easy to install, set up, and start using the monitor. I haven't had a professional compare the values using an actual water sample but comparing to some 3rd party test strips the values appear to be good. The app is great for keeping an eye on the water quality while I'm away and prior to using the hot tub. Overall, a great product and very useful for my purposes.

The calibration worked for us

Simple to follow programmed steps and the probe fits nicely in the pouches of liquid for calibration.

The EcO spa sensor and its companion hub performs its periodic tasks 24/7/365. In my opinion, it is the most economical device of its kind on the market.

I have a salt water spa the Caldera Geneva.
What a great saltwater hot tub by the way, but chemicals can still be challenging and expensive!
With the Eco start it’s a game changer.
No more mad scientist, mixing chemicals near the spa. This device tells you exactly what you need to add to the spa and then within an hour your spa will be balanced!
It’s really is that easy.
This device measures your chlorine levels and your pH level when both of those are correct very little things have to be done.
I’m stress free now, thanks iopool!

These test strips seem to be the most accurate test strips I have used.
