APP needs work
While it’s nice to see a lifetime energy usage, it’s equally important to see the daily & monthly usage
Worst app on the AppStore
Can’t log in, and if once in a hundred tries you’re able to log in, you can’t apply schedules, can’t change any of the settings because the connection gets lost, and you’ll have to login again. The issue is not the water heater itself, but the app’s connection to the AO Smith API
App Needs Improvement
Not a whole lot of useful functionality in the app… which is fine if it was reliable and you were able to consistently login to the app and it would stay connected to your water heater. But staying logged into and having it stay connected has been an issue. It’s current telling me my water heater is at 1450 degrees… another error. I must say it was nice when it does integrate with my Home Assistant, I liked having the historical data on my water heater and additional features HA integration added.

Won’t stay logged in
Every time I log into the app it only keeps me logged in for about 30 seconds before I get kicked out and have to log in again. I use the Rheem Econet app for another water heater that I have and that one never logs me out and the overall usability is much better. Come on AO Smith, is this the best you can do? This app needs a complete overhaul.

This App Sucks
This app is useless. It’s difficult to get it to connect with my water heater and does not have any useful functionality.
Not good
Cannot get app to register. Says QR code not valid. Tried to manually add. Wants a Device SN (different from the SN). Cannot locate it. Awful.
Garbage
This has got to be the winner of the worst app ever!! Nothing, and I mean nothing has ever worked since day one of water heater installation. At least the A. O. Smith app performed as expected.
Obviously if you need to know what’s going on with your water heater, like if you have a leak, or any other diagnostic notification you’re SOL with this garbage.

Doesn’t work
If I could give 0 stars I would. Can’t even create an account to hook my water heater to the app. Same error message every time. It says that there’s an error creating an account, contact customer service or try again.
It works
Seems to be stable now, hasn’t “forgotten” my hot water heater for a while now.
Reason I didn’t give it more stars was that there was a feature to see how much electricity it used each day by clicking on the in-app chart. Now you just have to guess based on their terribly scaled chart

App already broken
It doesn’t update. Have to quit and restart. At the moment it won’t let me log in. Account is there and I reset my password.
AOSmith: fire your app developer. They make you look bad!

Trash app doesnt connect
No connection
App, iCOMM Network Connectivity is terrible
I’ve tried multiple times to use this app to register my new water heater & activate the iCOMM connection to monitor & manage the device. Typically, I often get an error message that’s coming from their server basically saying we’re experiencing problems, please try again later. Plus the DSN is hidden behind a plate which is not clearly mentioned in the user manual. Not a fan!

Unusable
Won’t stay signed in, not much functionality even when you’re in there, not worth the frustration of downloading
Not intuitive to set up
I have 15 smartphone apps on my phone. This is the only one that I needed to call for tech support. It first asks you to get the QR code serial. No problem. The it asks for the Icom module QR which I couldn’t find so I went to the help which had a picture of the location but it didn’t match anything that looked the same on my water heater. I tried to connect it to WiFi like I have done with all of my other apps but it couldn’t find the icon module. Called tech support which they were really great and walked me through getting it set up. A little better app and they can avoid calls to tech support. The app itself is weird. There isn’t any refresh that I can see and I can’t tell if I am actually communicating. I think I am but it would be nice to see an indication. I googled it and supposedly there is an indication but I can’t find it. Maybe it was on a previous version. It seems like the person that programmed this app has never used a Smarthome app before.

Major infrastructure issue
I hate to be critical, but this app barely has any feature. More importantly, constantly log user out of the app. I also use Home Assistant and Home Assistant constantly report connection being unavailable. This signals, there are some major infrastructure issue associated with this whole setup that needs to be addressed. This kind of issue has long been resolved many times over. Please fix

Barely Workable App
Update: July 2026. Dropping a star since they still haven’t fixed the very basic interface problems. Various buttons are still blank and non-functional. The app clearly isn’t a priority for the company.
It lets me change modes remotely, so that’s good I guess. But the electricity usage tracking chart is pretty much useless. And various buttons, including the back button when you go into settings, simply turn white and don’t work sometimes. Very poorly programmed and QA’d. As such, don’t trust that it will do what you want when you need it to.

Doesn’t work
Went through the steps to both scan and manually enter my water heater multiple times with no success. Not wottth the trouble
lacks a common but important feature
The app lacks an important feature to automatically switch mode in Schedule. For example, we want to use Hybrid mode during day time but Electric/Vacation mode at midnight e.g., 12:00am - 8:00am.
It might be a little counter-intuitive why I list Electric or Vacation mode together, because these two modes are quiet, while Hybrid mode indeed causes noise during midnight as it will use heat pump, especially you have in-house model.
Every time the hybrid mode works during the midnight, it wake people up, especially your home is quiet. We have to manually put the mode to Electric mode, or manually switch the mode to Electric mode before bedtime.
The app’s current function cares only efficiency or cost-saving, and use this for selling point, but never thinks that we need a quiet mode during midnight. I saw people discussed about this feature on Reddit three years ago, and frustrated to see this feature is not available until today.

If I could, I give it zero stars
I had the previous app that provided little assistance or use. I hoped that in this day and age A. O. Smith would produce an app that’s useful. Unfortunately when I tried to sign back in, it did not recognize my water heater. I tried to register but it did not recognize my serial number. Called, on hold no action. Called again and spent 45 min with a technician who informed me that he couldn’t fix it but his team was world be able to but it was a holiday and it might take a few days. That was 2 weeks ago. Heard nothing. Still not able to access the app. Called again. On hold. Called again and the automated system said they call back as the wait was 10 min. Two days later, still no callback. Don’t buy from A.O. Smith. Don’t bother with this app.

App will not connect
App is a janky mess, tons of problems most of all will not connect to water heater.
