User reviews

Just awful

This app may be the worst that I’ve ever used from any company. It fails at its one job of letting me control my water heater. Says a lot that AO Smith doesn’t put their name on their own app. Regardless, I will never purchase another one of their water heaters.

App never works

App never works. when you get an error message it has a support number that is not a valid number! Works about as good as the AO Smith water heater I bought.

Worthless Ap

I have tried numerous times to connect to my water heater. Each time I get an “Unknown Error” message with a customer support number. When I call the customer support number, I receive an error message stating that the call cannot be connected and I am instructed to check the number and try again.

Simple Doesn’t Work

Simple doesn’t work. Can’t even add back my water heater anymore after it auto removed it and logged me out. Pointless app.

Useless

Absolutely useless app. Can never get it to connect or work. CSR at AO Smith are also useless, with no helpful information on how to get the system to connect. Two CSRs hung up on me and one told me to restart my phone.
