Harvia Smart Sauna Solutions for Hotels, Spas, and Rental Properties
Running a sauna in a commercial environment requires reliability, consistency, and control. Guests expect the sauna to be ready at the right temperature, every time. Operators need predictable performance, manageable energy use, and reduced staff workload. The smart sauna ecosystem from Harvia brings these needs together through three integrated components: Harvia Fenix control panel, MyHarvia 2 app, and MyHarvia Smart Sauna Sensor. Together, they transform sauna management from manual oversight into structured, intelligent control.

At the heart of Harvia’s smart ecosystem is Harvia Fenix control panel. Designed for professional and private sauna environments, this is a tool built to make sauna operations predictable, efficient, and effortless.
By learning how your sauna heats, Harvia Fenix automatically calculates the ideal start time for each session. This means your sauna is ready exactly when guests arrive, without staff having to guess or preheat unnecessarily - saving time, reducing energy costs, and ensuring a consistent, comfortable experience every time.

In addition to the MyHarvia 2 app, data from the MyHarvia Smart Sauna Sensor is collected on the harvio.io web portal, a desktop platform that provides a full view of all your sauna sessions and all your saunas while offering the same monitoring and control tools as the mobile app.

The sauna session data stored in your MyHarvia account can also be accessed through the programming interface (API). The MyHarvia API documentation is available at https://harvia.io/api.
The cloud-to-cloud integration through API enables integration of Harvia products to remote monitoring, home and building automation systems as well as other 3rd party services. The API offers the same monitoring and control tools as the mobile app and Harvia.io portal.
