“Remote control disabled”

The last update somehow lead to the remote control feature from the app being repeatedly disabled. It requires that you “confirm safety from the UKU panel”, thus defeating the purpose of using the app at all 🤦🏻‍♂️. I think I’ve confirmed that safety four times now, it keeps disabling itself. Man this sauna was too expensive for the app to be so lame.

Impressive

It’s incredible that this company was able to make an app with so few features have so many bugs. I honestly would not have believed it was possible. Sometimes it will show multiple error messages at the same time. Seriously this app needs to do one thing and it does it like 20 percent of the time.

Awful update

I had no issues with the previous version. The scheduling feature on this update is terrible. You also can’t just start the sauna and put it on a timer to auto shutoff.

Terrible update

Very glitchy. Can no longer turn on sauna via WiFi

Terrible app - do not buy HUUM

This app is terrible. Problems with starting or stopping - wifi connection problems, was just kicked out of the app and I can’t log back in. I work in IT - I know this is not a me problem. I have been in contact with the developers and they cannot provide a stable solution. Continued problems. I’m getting a different wifi controller app to connect because this one just doesn’t work. Very disappointed.
