Configuration Options

1. Earliest Start Time Earliest time to start the appliance.

2. Latest End Time Latest time to end the appliance. Set it to same value as earliest start time to cover 24h. If set to smaller value than earliest start time, it automatically refers to following day.

3. Duration Required duration to complete the appliance.

4. Remaining Duration Entity Optional entity which indicates the remaining duration. If entity is set, it replaces the static duration. If the state of the Remaining Duration Entity changes between Earliest Start Time and Latest End Time, the configured Earliest Start Time will be ignore and the latest change time of the Remaining Duration Entity will the used instead.

5. Price Mode Selects whether the sensor shall react on the cheapest or the most expensive prices between Earliest Start Time and Latest End Time.

6. Interval Mode Selects whether the specified duration shall be completed in a single, contiguous interval or can be split into multiple, not contiguous intervals (intermittend).

Sensor Attributes

1. Earliest Start Time Reflects the configured Earliest Start Time.

2. Latest End Time Reflects the configured Latest End Time.

3. Duration Reflects the used value for duration, which is either the configured duration if the Remaining Duration Entity is not set; or the state of the Remaining Duration Entity.

4. Remaining Duration Entity Optional entity which indicates the remaining duration. If entity is set, it replaces the static duration.

5. Interval Start Time Reflects the actual start time of the interval, which is either the configured Earliest Start Time or the latest change time of the Remaining Duration Entity if the state of the entity changed between Earliest Start Time and Latest End Time.

6. Price Mode Reflects the configured Price Mode.

7. Price Mode Reflects the configured Interval Mode.

8. Enabled Set to true if current time is between Earliest Start Time and Latest End Time.

9. Data List of calculated intervals to switch sensor on, consisting of start_time, end_time and rank (for Interval Mode intermittend only).
