Smart Heat project is carried out under the Interreg Estonia-Latvia programme.

The main objective of the project is to develop a wireless wall-mounted control panel that both partners can add to their product portfolios while operating in different market segments: HUUM in smart sauna systems and Istabai in smart home automation systems.

Products and solutions of both companies will be promoted through a joint marketing campaign to help each other enter new markets and secure new clients.

An invaluable added benefit of international cooperation is raising the expertise and know-how of both companies and, ultimately, strengthening their foothold and reputation as leading technology companies in their respective countries.

  • joint marketing campaign (conference attendance, business trips, increasing the online presence of both companies and connecting their online channels, producing joint promotional materials)
