Smart home energy · Voltlight
Know what every appliance costs — before the bill does.
Nova One turns your meter cupboard into a live dashboard: it reads the smart meter every second, recognises individual appliances and shows exactly where every euro of your energy bill goes. On a dynamic contract, the app tells you when power is cheap — and what to run then.

Nova One found a crawl-space pump that had been running non-stop for six years — € 14 a month, gone with one tap. It paid for itself before the first winter bill.
