Warning - No Longer In Development - Do Not Buy. They introduced some bug so sensor won't stay connected. 3+ weeks back and forth with support, no solution in sight.

App doesn't allow you too add chemicals unless its iopool chemicals. I have a mix of iopool and other brands of chemicals(because they're always out of chemicals) & I can't add them to my inventory or complete the treatment because it thinks I don't have certain chemicals. The measurements are also terrible. What's on the container, what's the app tells you and the scoop that you have to buy from them are all different & have to be converted. Now you can't even check out. app just crashes...

Hi Robert, you can always complete or validate a treatment even if your iopool inventory is empty, so you can use your own chemicals. In the app, product quantities are expressed in "iopool spoons" (included in the EcO Start pack) for convenience, or by weight. You have the choice, so I don't understand your remark. Please contact our support team

Well, I'm not completely convinced. I like to think that I'm pretty tech. Savvy, i have a complete smart home and theater, so I'm pretty smart about hooking up this kind of stuff. But I will give it a few more tries to see what's going on with this gatewave, why it will not connect? The good part about this is I bought it through a third party that sells this EcO Product and I can send it right back to them. With no problem, no hassle. We'll try to connect 3 more times if not it goes back. Wow

Just got it going. So far it works well! Pretty easy to set up. It would be nice to be able adjust the ranges of orp and ph like I can with temperature. I like the pH on the lower side and orp a little higher than what the green range is.

The device and app work well for pH and alkalinity balancing of a hot tub. But they way it handles the disinfection potential of the water in the tub does not work well if you are using an ozonator. But if you understand why that is...it's not hard to work around. But if you don't understand that...using this could be problematic.

great support team. I wish they had a widget for Android so I can get a quick glance on the pool without opening the app. The notifications are not very useful.

Hi Wissam, thanks for your review. We may introduce a widget in 2025
