About

Helen Energy Price is an integration that brings Oma Helen electricity consumption and estimated costs into Home Assistant. It talks to the vendor's cloud, is added through the UI, and works with exchange, market price and fixed price contracts. Sensors report the total energy cost of the ongoing month, with attributes such as last and current month consumption and daily average. An optional transfer cost sensor covers the transfer contract, including its base price. Hourly consumption and cost statistics are imported for the energy dashboard, with the last seven days backfilled on first setup. Settings cover VAT percentage, contract type, a custom unit price or base price override, and the delivery site chosen by its meter number.
