Set a custom optimization signal to optimize the VPP on.

• Custom signals can be set for a maximum of an hour in the past compared to the present.
• Overlapping time periods are not permitted.
• All time periods should be defined from the present moment until the latest endTime defined.
• All time periods must have an amount specified.
• You may specify varying time periods of your preference, which may differ from one to another (min 15 minutes).
• To achieve optimal results, provide time periods covering at least 7 consecutive days.
• In case a custom signal is absent during an active time period, the custom optimization will be disregarded.
