### 4/5 — Good upgrade but still could be improved

*2025-04-05*

Nice upgrade from old version. Seems quicker. Do wish the actual system status was displayed on main page. It says mode but I have to drill down to see if system is actually operating. Would be nice if it would show if heat or ac was running. Also for some reason the forecast can be messed up for my address. May show 40 degrees when it is actually 72 as example.

### 4/5 — Before Update I gave a 4 star

*2025-03-28*

Since the update nothing is working.  Taking minutes to login not seconds.  Updated the wall unit still no better.  Yes, they are on the same network.  I have been over an hour trying to open the app with my heat pump info.  It logs me in but that’s it.

### 4/5 — Love the app but..

*2025-02-28, version 1.8.11*

Everything works as intended however I wonder where the outside temperature comes from. For example: it’s now 63 degrees F and the app says 47 degrees. 
I can’t find a way to correct this.

### 2/5 — Loses Connection To Star

*2025-02-28, version 1.8.11*

Probably the stats fault but it’s annoying as piss. The stat somehow loses connection to the app. When it does you can’t tell, and you have to go on the stat itself to reconnect. Also we need more comfort profile settings.

### 1/5 — Difficult Setup and App

*2025-02-24*

This ION thermostat was difficult to set up and the installer tech was unfamiliar with how to set it up to get the app for the iPhone. I phoned ION tech support then and they helped somewhat, but after I got the app from the App Store, I was eventually able to learn how to manage it.  My only wish is that the app would have a setting to turn OFF the Scheduled Settings.  Currently, there is no way to do this that I can determine.  The only way I can control my settings at night is to turn the unit OFF at night with the app.  Then, I need to turn the unit back On in the morning.  Otherwise it would continue on with the scheduled settings throughout the night when it is not needed, as we would be too hot underneath the covers.

**Developer response:** Daer Bud917,Thank you for bringing this to our attention! We apologize for any inconvenience caused, we request you to share the below details at resdigital@carrier.com along with a screen recording/screenshot of the issues for technical team to look into: Primary email address, Account username Sincerely, Ion Home App Team.

### 4/5 — Works well

*2025-02-15, version 1.8.10*

Good app overall, but it crashes after changing apps recently.

### 1/5 — Update loses data

*2025-02-13, version 1.8.10*

Updated this app and now it says my home has no devices. When I try to add my device back in using the QR code, it requires me to name it, and then rejects every name I try with an error about an empty string and cannot proceed further.

### 1/5 — Won’t connect after update

*2025-02-13, version 1.8.10*

Since updating to 1.8.10, app cannot connect to my home thermostats. Ion support website seems down as well.

### 4/5 — Great App…

*2025-02-09, version 1.8.9*

The app works great and is user friendly. A lot of options for programming for comfort. 

Wish it worked with Google Home!  And would be nice if I could see Outside and Inside Humidity % on main screen.

### 1/5 — Ion Controller.

*2025-02-08, version 1.8.9*

Ion controller never stays connected to the server! Sooooo aggravating!
