A node to save money when power prices are changing. Saving is done by postponing power consumption until the price is lower. You can configure maximum number of hours to save in a sequence, and minimum time to recover after a maximum saving period.
A prerequisite is that you pay for electricity per hour. The node is primarily made to be used together with Home Assistant, but it has no dependencies, and can be used separate from HA.
