Connection Error
The basic requirement for the App is to connect to the appliance.
It stays connected for a few days and then the dreaded connection error shows up.
I’ve never experienced this with other brand IoTs.
For a luxury appliance like Sub-zero/Wolf/Cove, this App is a big embarrassment.
I have the double oven, Sub-zero and Cove and all three are showing connection errors.
Why is this so very difficult?? I have stopped using the app now.

No HomeKit integration
It’s 2026 and this app still doesn’t have HomeKit integration. It works with Alexa and Google but why not Apple?
Works when it finally connects
I had to have Wolf help me connect my appliances when I first set up the app. It worked for a while. And I loved having the information. It lost connection and will not reconnect, so I guess I will call customer service again.
Wi-Fi will not connect in three of my Ford devices
I have a brand new 3050 refrigerator 1850 wine cooler 2450 freezer and Wolf oven. Only the freezer can connect to the Internet. The others don’t find the Internet, even though it’s extremely strong signal. The app does not allow you to delete a network you’ve entered.
Bad update
Latest update breaks everything. Cant connect at all. Hangs on Bluetooth. Then hangs on wifi. Horrible.
Fix the app!
Everyone complaining that the last update caused appliances to lose connection and can’t reconnect and your only answer is to tell everyone to call customer service??? High end equipment, ridiculously low end app!!
Keeps breaking with connection error
I initially thought I had a problem with my brand new subzero but after adding the new wolf dual range, both frequently break with connection errors. I have to delete the Bluetooth connections and redo the setup. Absolutely annoying.
The only thing that is required is to be able to connect to the appliances when you open the app. How difficult could that be? I believe there are serious quality issues before releasing the app to production. I have now stopped using this app altogether.

Updates break app-appliance connection
The app is great when it works. However, every so often a bad app or server update is pushed that breaks the app’s ability to communicate with my SZ fridge. I have an older Integrated/Designer fridge that does not have an internal control panel (only physical options for power/ice maker/alarm). Everything else from fridge/freezer temperature controls, ice maker settings, and filter status are only visible and accessible via the app. So when the app breaks, the functionality of my fridge is particularly limited. I wish Sub Zero had better QA or testing prior to releasing their app updates. The bug is usually fixed within a week or so, but it is nonetheless frustrating to lose control of your expensive appliances even if it’s only temporary.

Works great when it works
After recent update my appliances can no longer connect and keeps telling me to pair my device to the appliances but it will not pair with Bluetooth
Update broke connection
I just updated to 4.5.2. My iPhone account t was logged out and my connection to the subzero refrigerator was broken. App will no longer connect to fridge. I logged out- I logged in. No connection. I deleted app and tried to reconnect- no connection. Really surprising how finnicky/useless this app is.

Daylight savings and other opportunities
I woke up today to the clock of the oven not updated. I assumed the app would do it, as there is a setting for the time zone (PST in my case) that it is still as PST.
I also assume the firmware may be outdated, but there is no indication that it is, or how to check for it.
For an item that consider “luxury” it is really under performing, as the oven should have auto updated over WiFi or the app should have signaled to do it, and indicate that the oven firmware is updated. More basic devices, like my cat feeder, have that functionality.

App is unstable
When this app is working, it is very helpful. Unfortunately, it drops appliances randomly, and then you have to put the appliance back in again and again and again. It also randomly requires your id and password, which is very annoying.
Celsius now available
Finally, Celsius is available to be selected in the app!
Hangs after iOS 26.x
Takes a long time to launch, allow changes in set points in app but this doesn’t result in changes inside the SZ. Quickly hangs after that. All this started after the iOS 26.0 update. This has been going on a long time now without a fix even though we’re now on iOS 26.3. Yes using the latest app.
Prior review:
This app is simple to use and provides notifications for door open or filters needing replacement. While it does report set points, it does not give any warning when actual temperatures increase well into warm conditions.
Consequently you get no indication that you have a problem until it becomes obvious when you see food thawing or open the door and check temperatures.
There are virtually no diagnostic flags.

Water filter reset
There is now no way to reset the water filter life on my Subzero ic30ridx after this update.
Regressive update!
Whatever you guys have done in your most recent update, you have introduced regressive bugs into your application. Whenever I open the app now it takes forever to load my appliances….” loading additional appliances.” another issue I’ve noticed is that when I change my refrigerator from short vacation to normal or normal to short or any variation there of while the change is submitted to my refrigerator the application does not reflect the change. Come on guys test your applications better.

Won’t allow me to set Night Ice
Has this been updated for iOS 26? I can’t set my ice maker to night ice (or anything else)
and the app is saying my ice maker is off when it is on. Wondering when this will be fixed.

The worst app I’ve ever used
Oven keeps disconnecting from WiFi and it’s nearly impossible to reconnect using this app. Total junk! Majority of our Wolf appliances have had issues and have been replaced. Don’t waste your money buying anything from Wolf.
Big disappointment
I expected much more from this app and this appliance at this price point. I purchased this and it was installed new 4 weeks ago. I assumed it would provide current internal temperature for both refrigerator and freezer. It did not.
I lost power 5 days ago when a breaker tripped and I was out of town. No notifications. Went I got home everything inside was warm. My app only said ‘refrigerator offline’ while I was out of town.
But it will notify me if someone changes the internal temperature set point. I have yet to figure out how that would be helpful.
