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!
