Mostly Featureless and Unpredictable

First off, our family has used A.O.Smith products since I was growing up. I was always under the impression they made high quality equipment. Unfortunately when I bought a hybrid unit for the first time… This turns out not to be as expected… The app never seems to reconnect to the hot water heater after closing the app. I have to re-enter credentials every time I want to check on the status. It also won’t send an alert if the unit loses power which would be a simple monitor from the server end. It won’t give you the option to be alerted when it’s running or alert when it’s topped off… Speaking of servers, the one they are using to run this app is terrible and has been down for over a week with no access to the controller from the app.

Now hear me out, these are obviously all 1st world problems and in the grand scheme of things very tiny. However when you pay a PREMIUM for a product expecting to be able to use the features you paid for, and then turns out to be as flaky as it is… makes you question whether or not you want to purchase any other product from them.

And don’t get me started on the useless tech support phone number. I called 4 different times before I was able to land a decent technician. If you can read this before purchasing one of these hot water heaters, shop around. Hopefully there are more reliable brands out there.

When this works it is great. Problem now is that the app apparently did an update, or just decided to forget my data info, and now does not recognize my water heater anymore, so it wants me to re-register my water heater. Problem is that it is in our vacation condo and we turn the heater on the day we are heading there and turn off the vacation mode. So now we will have to get to the condo to turn on the hot water! And wait for hot water. Kind of defeats the point of controlling by Wi-Fi if the app cannot keep your info, especially for an update. Please fix the bugs! When this works it is very convenient but when it doesn’t the water heater is just another water heater that you manually have to operate.

Needs Major Improvement

Maybe it’s because it’s so new, but this app is trash. Unless you have a rate plan with your electric company, you really can’t do much with the app. There’s a “schedule” feature, but all it does is “top your tank off with hot water” at whatever time you set it for. Dumb. Why not create a schedule feature where I can leave the temp at 95° all day when I’m not using it, and then set it to go up to a desired temp at a certain time for bath time, etc. To me, that’s what a schedule feature should do. I try to manually do this, but I’m updating several times a day, and sometimes I forget, then I have colder showers, or I’m paying extra to keep water hot all night when I’m not using it. And half the time, manually changing the temp on the app doesn’t work either. It will say “updating set point” and then when it updates, it’s the same temp I started with. This app definitely needs some hard work. For what I paid for the water heater I know y’all can afford to hire someone to work on this.
