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.

Terrible

I repeatedly have trouble with this app and it’s predecessor, the AO Smith app. I am often logged out and get a generic error when trying to log back in. I call phone support and am told, “they’re updating the app, please try again in 24 hours.” If that’s the case, the app should describe that maintenance is underway. This same condition has been the case for the two years I’ve owned this water heater. Terrible app and no communication from the company.

Helpful when it works, which is NEVER!

This app works one time, doesn’t, next works again, then doesn’t!

I’ve had to set up my water heater. I don’t even know how many times because it forgets it.

If you don’t log into the thing regularly it forgets you faster than an Ex!

Worst app on my phone tbh!

Horrible app, never works when required. Keeps signing out and removes my heater from profile. Even to submit the feedback on the app it required multiple attempts and yet couldn’t do it. Hire some good developers!!

Incredible bad

One of the worst apps out there. Why is AO Smith letting this damage their reputation? Keeps disconnecting. Keeps forgetting devices. Unresponsive for no reason. The list goes on.

Doesn't Work

Don't bother downloading this.

Failed even creating an account

Could not even onboard with this app. Their team has been notified though and is actively investigating the cause, though, according to the message shown. Will try again next week.

Unreliable

The app does not execute the commands that it proposes to do. After I’ve input my schedule to top off hot water, it doesn’t ever follow through with it.
