The Tariff Data Layer for HEMS
Power your home energy controller with dynamic day-ahead prices, static TOU tariffs, and feed-in rates - all in one unified API.
HEMS controllers need to know three things: what electricity costs right now, what it will cost in the next 24 hours, and what the grid pays for exported solar energy. Sourcing this data for 28 European markets individually is a major integration burden.
tounify normalizes all three tariff directions - consumption, feed-in, and grid - into a single JSON schema. Your HEMS logic receives the same structured data regardless of country or supplier.
