The components at a glance

ETHERMA SMARTBOX - The heart of your heating solution

At the heart of the system is the SMARTBOX - the intelligent control unit that networks the Smartcube, heater and ETHERMA SMART app. As a radio receiver, it receives the signals from the thermostat (SMARTCUBE) and transmits the control commands to the heater.

Your advantages:

  • Control center for all SMART devices

  • Simple integration - even in existing buildings

  • Invisible installation behind heating panels or in flush-mounted boxes

  • Compatible with the ETHERMA SMART app

ETHERMA SMARTCUBE - The smart thermostat for precise room control

The SMARTCUBE is the intelligent input device within the ETHERMA SMART SYSTEM. As a wireless thermostat, it sends temperature and control data to the SMARTBOX, which forwards it to the heater. Together they enable precise, energy-efficient control - completely without wiring.

SMARTCUBE Key Features:

  • Precise temperature measurement in the room

    Control via buttons or app

    Weekly program & time control

    Window open detection & child lock

    Compact design, easy to integrate


With the SMARTCUBE, you not only optimize heating comfort - you also save energy and increase user-friendliness to a new level.

With the ETHERMA SMART app, you have your entire heating system in the palm of your hand - at home or on the move. Rooms can be controlled individually, schedules can be adjusted and energy consumption can be conveniently analyzed.

App highlights:
