### 1/5 — Cannot login anymore

*2026-08-14*

For unknown reasons, it prompts me for my user/pw.  It now just returns login failed error.  unable to use this app anymore.  sigh. the new app is also non functional.  incompetent software management.  Forced to go to a new app that does not work most of the time.  At least this version worked consistently.  Now they won't let you use it anymore.  Stuck with managing multiple thermostats at the units.

### 1/5 — Cannot login anymore

*2026-07-07, version 1.6.1*

### 2/5 — No effort

*2026-01-04*

I have never seen such a wasted opportunity. There’s no option to be flexible. Only able to create one schedule. What about a summer schedule? What about an away schedule? The quality of the components sure better be good because we have paid top dollar for a device. I’m talking about the signature model. The app is also not connecting with either Google or Alexa. This is one of the main reasons I spent the extra money over the home model. When I called to report, it would not connect, it is nice that it was easy to reach support, but I was surprised to hear that they ladies say that you shouldn’t believe the reviews because  of the kind of people that leave reviews.  I thought to myself at the time how asinine that attitude was since I was calling because none of the features that I paid for are working. I bought mine on eBay and the ability to return. It is kind of a lot of effort. The jury is still out though. I’m really tempted to go through that effort.

### 1/5 — Does not integrate with home apps

*2025-12-23, version 1.4.5*

Integration with Google Home and Amazon Alexa does not work despite documentation stating it does

### 1/5 — Extremely Disappointing

*2025-12-08*

This app is not good. Or the chips on the controllers are bad. It can’t change the temperature on a controller. Sometimes it randomly turns the floor heat on. The refresh rate with the wall controller is like once every six hours.  I don’t know how someone could have screwed a simple WiFi controlled thermostat so bad. Instead of developing an app they should have taken that money and paid for a partnership with Ecobee/Carrier.

### 1/5 — Google Home Integration

*2025-10-03, version 1.4.5*

App allows you to adjust temp but has not been updated in over a year. Google Home integration is now broken. Should be a priority to fix.

### 2/5 — App not maintained

*2025-03-01, version 1.4.5*

Loved this app until they stopped providing updates and it just quit working.

### 2/5 — Archaic

*2024-12-21*

It surprises me that with todays a corporation such as this has such a useless app. The app has minimal functionality that’s it’s almost worth not having one. You would think that it would at least have a vacation/ away mode that could be set. All it provides is current settings and energy use. The only reason I gave it a two is because the mat does heat the tile during the times programmed. The rating could be higher if it wasn’t for such an archaic app

### 1/5 — Shockingly bad

*2024-12-10, version 1.4.5*

Very primitive app that only works intermittently. If you saw the app first, you wouldn’t buy the floor system.

### 1/5 — App is Nonfunctional

*2024-11-25, version 1.4.5*

Should be deleted from App store. It is better for you to log on to the website directly mynuheat.com and control from there.
