EcoWatch, the electricity price clock

An electricity price clock shows when electricity is cheap and when it is expensive, without an app. EcoWatch fetches tomorrow's hourly prices for your price area every afternoon and lights a ring of LEDs around the dial: green for cheap hours, yellow for medium, red for expensive. Run the dishwasher, charge the car and heat the water when the ring is green. Made in Järna, Sweden, in three sizes.
