The review by “horrible “ previously submitted here is almost exactly what I have experienced . It’s incredible and mind boggling how bad this app is and the fact they released this app in the first place and can’t fix it shows they couldn’t care less. As if that was bad enough , customer service is even worse .I have had reps hang up on me and supposed “supervisors” not return calls when I am told I will get a call back in 5 minutes -because they are tired of pretending to trouble shoot this when they don’t have a clue and darn well know it doesn’t work . I have now been told I will get a return call over 10 times and yet they simply don’t call back. It’s disgusting and reprehensible that management allows them to get away with this but apparently no one cares . I have now spent over 35 hours trouble shooting this and wasting my time on this with people who just don’t care . Friedrich customer service is by far the worst I have ever experienced. Nothing comes close .

I have wasted HOURS of my life on this. I have called them 3 times and received 3 different “solutions.” First they said they’d call me back. They never did. Second they said to disable my 5GHz WiFi so I did, no help. The third time they said my 1.03 firmware was old so they sent me new boards which I replaced (not straightforward btw) and now I’m running 1.04. They also updated the app (in the last week I see) and it now says the device is in my profile and I can see the WiFi symbol on the control panel but it’s totally missing from the device list on the app. I’ve had these units for 4 months now but didn’t use them at first due to where I live. They cool well but are a little loud and this WiFi problem is maddening. If they don’t fix it soon I hope they learn how to spell CLASS ACTION.

Had tried several times unsuccessfully and then read that my home network had to be transmitting 2.4 (not 5.0) so I switched to 2.4. And you have to turn off “private WiFi address “ setting for the home network that you will be using. Then I read somewhere that you need to ensure that the display on the air conditioner needs to stay on the entire time. You can do this by pushing the up and down arrows. I believe you get about 10 seconds before the screen goes black, so just make sure you push one of the arrows before it goes black. I followed the above two steps along with the other steps on the app and it worked! As far as using the app itself, I haven’t played around with it yet. But at least I now see my Kuhl unit on the app.

I had success connecting my two new WallMaster units without too much difficulty. I can control them from my iPhone, iPad, and even my Mac. The bug I’ve encountered is that the temperature changes sometimes don’t “stick” even after repeated attempts. The workaround that seems to work (usually) is changing another setting, like fan mode, then returning to temp, and then temp changes will actually take effect. I’ve had to do this with both units a couple times. Feature request for the app would be for when you tap on a device to reveal its settings, it shows the name of the device at the top (e.g. Bedroom). HomeKit integration update would be lovely of course but not gonna hold my breath on that.
