Themo - step into the future

First truly intelligent thermostat that checks the electricity price when heating your home.

Do not pay more than You should

Themo uses thousands of data points to understand when to switch on your heating. For this it takes into account real time electricity spot price, outside weather, your preset temperature levels and your home unique consumption profile.

Intelligent heating keeps your floor warm while you pay up to 60% less to your electricity supplier. Themo saves on average 8€/m2 per year.

Powered by renewable electricity!

The price of electricity always drops when there is a lot of solar and wind energy being produced. Themo breathes as one with the nature and heats up the floor when there is cheap and green energy available in the grid. As less fossil fuels are needed, a 5 m2 with Themo intelligence can save up to 500kg of CO2 emissions in a year to your environment.
Themo interactive LED circle changes its color based on current electricity price. By glowing red, it indicates that the price is at the peak and it would be a good idea to wait with using your other energy expensive home appliances as well.
