 OpenDTU-Database adds an ESP32 LittleFS Database and two energy charts, a column chart of the last 25 hours and a full calendar chart.
 
+There are 3 new APIs available, returning JSON strings:
+
+| API               | returned values |
+|-------------------|-----------------|
+| /api/database     | returns all recored data points from the database with total energy value |
+| /api/databaseHour | returns the energy per hour for the last 25 hours |
+| /api/databaseDay  | returns the energy for each day |
+
+Each data point has the following format:
+[ _year (00-99)_, _month (1-12)_, _day (1-31)_, _hour (0-23)_, _energy (Wh)_ ]
+
+Example: [23,6,30,15,132.995605]
