    About the Brand

    The founder of HUUM, Siim Nellis, is actually the third one in his family to produce sauna stoves. His grandfather was a skilled oven-builder with a lot of experience in building sauna stoves and his father is also active in sauna stove production. Siim continues to carry on these traditions, connecting the Estonian sauna building knowledge with modern design and innovative technology.

    Our team consists of enthusiastic sauna fans who believe in the importance of sauna for health and well-being. All of us grew up in Estonia where it would be hard to imagine not going to the sauna at the end of a busy working week, after a cold winter day or on a nice summer evening in the countryside. Sauna means taking time for yourself, regenerating your body and mind, staying healthy and just feeling good. That is why we think that sauna should be available to everybody and everywhere.

    Heat your sauna comfortably with HUUM mobile app

    HUUM mobile app

    The main benefit of this is you don’t even have to be home to heat your sauna. You could be anywhere and have your sauna hot and ready at exactly the moment you step in the door. This is a great advantage for many home sauna owners as well as accommodation establishments.


    Save time with HUUM mobile app

    A HUUM sauna controller with the mobile app remote control option has two important advantages.

    Firstly, it saves you a lot of time. Let’s say heating the sauna takes about an hour. With a regular sauna controller, it would mean that once you arrive home you would still have to wait an hour before you can actually use it. With a mobile app remote control, you can start heating the sauna even without being home yet. You can just activate the sauna heater from your phone and spend that hour finishing up at work or exercising at the gym.

    HUUM mobile app works with UKU Wi-Fi sauna controller

    If you would like to heat your sauna with the HUUM app you first need to purchase a sauna controller with that feature. So, you should have UKU Wi-Fi controller installed in your sauna. These controllers can be used with any manufacturer’s electric heaters as long as they work with remote control and have a temperature control function.

    Once the controller is in place, all you need to do is download the HUUM app into your phone and connect it to your controller. To do that, just follow the instructions on the screen and insert your sauna controller’s ID and code when requested. After that, you are ready to heat your sauna from the app and enjoy all its features.

    Prepare your sauna experience with a few taps on the phone

    HUUM mobile app is about more than just switching the sauna heater on and off. It provides several useful features for adjusting your sauna experience to your wishes.

    First, let’s go over the basic functions. When it comes to heating, you can choose the beginning and end time of the heating and set the desired temperature. Thanks to the door sensor of the UKU control unit, the app will know if you have left your sauna room door open and will not allow heating in that case.

    While the sauna is heating, you can check the current temperature at any moment to see how it’s proceeding.

    If you already know exactly what time you need your sauna to be hot, the timer function comes in handy. Just activate the timer and have the sauna heated exactly by the time you arrive home from a workout or in time for a sauna party.

    HUUM sauna controllers can be connected to the lights, ventilation and steamer functions which can be controlled through the mobile app as well. In order to do that you must first activate these functions from the control panel on the wall.

    The number of app users is unlimited. Anybody who has the sauna controller ID numbers can download the app and connect it to the heater. This way all the family members can heat the sauna from the app and always see if the sauna is already being heated. Friends invited over for a sauna session can keep an eye on the sauna temperature to know if it is ready yet.

    HUUM mobile app comes in the following 6 languages: English, German, Russian, Italian, Finnish and Estonian.
