ETHERMA SMARTCUBE - from fall 2025 The smart thermostat for your heating solution
The ETHERMA SMARTCUBE is the intelligent room thermostat of the new ETHERMA wireless solution. As a transmitter in the SMARTSYSTEM, it reliably detects the room temperature and transmits all control commands wirelessly to the SMARTBOX, which regulates the connected heating system.
The SMARTCUBE offers everything that modern, energy-efficient heating needs today: Radio control, weekly programs, window open detection, child safety lock and app connection. Whether in a new build, in a smart home or when retrofitting existing heating appliances - the SMARTCUBE ensures convenience, control and maximum energy efficiency.
Your advantages in detail
App control included
Together with the SMARTBOX, the SMARTCUBE can also be controlled via the ETHERMA SMART app. Whether from the couch or on the move - you always have full control over your heating solution.
Sustainable & safe technology
The SMARTCUBE is based on durable electronics and uses radio communication with minimal radiation (868 MHz). The battery-operated solution works independently of the power grid and meets the highest standards for low-electrosmog control and environmentally friendly heating.
Intuitive operation with clear user guidance
Large control buttons, clear menu navigation and visual feedback make operating the SMARTCUBE child's play. Settings such as temperature, time programs or vacation mode can be adjusted quickly and easily - directly on the appliance or via the app.
eINK display - energy-efficient & elegant
The high-contrast eINK display only consumes energy when switching - similar to an e-book reader. This means: extremely low battery consumption, long runtime and perfect readability at all times, even in sunlight.
