Tempo is a device which aims to  reduce the cost of showers and baths in homes by calculating the most efficient volume of water to heat in an immersion based on historic usage. It will heat water when there is surplus renewable energy on the grid, in effect turning the humble immersion heater into a virtual distributed energy store.
