Solutions
Energy optimization designed for you
We help you understand, control, and reduce energy consumption in exactly the system that costs you the most.
Spa
Cut your biggest energy costs
Spas and pools consume enormous amounts of energy. We help them work smarter — heating when it makes sense and saving when it doesn't.
Heat Pumps
Optimize heating and cooling
Whether you're heating or cooling, heat pumps are powerful tools. We make them smarter by responding to electricity prices and weather forecasts.
Vacation Homes
Monitor and control your energy consumption
Know exactly how much electricity you're using. Adjust everything from anywhere. Reduce costs by using electricity when prices are lowest.
Price management
How you save on your energy costs
Your energy consumption is automatically managed based on electricity prices, so power is used when it's cheapest.
Electricity prices are calculated as:
Spot price
Real electricity prices hour by hour
Grid tariff
Cost of electricity transmission
Taxes and VAT
Government levies and charges
