===== Application Programming Interface (API) =====

==== Direct loads control ====

| ''load_set[i]''   | bit | R/W | Managed load state; 0=off, 1=on; i = 10..17 |
| ''analog_out[i]'' | int | R/W | Analog output value in % i = 10         |

===== Cloud Optimization (Consumers timetable) =====
**Cloud optimization** allows writes from Cloud/Edge to consumer timetables, changing consumer's behavior during specific time periods (e.g. Smart Grid functionality).\\
Following table and use cases below explain the usage of variables in different scenarios.

^ Variables ^ Description ^
| ''timetable_cloud_once[0..7]''      | Enables executing 'Once' actions from Cloud: 1=enabled. |
| ''timetable_cloud_recurring[0..7]'' | Enables executing 'Recurring' actions from Cloud: 1=enabled. |
| ''timetable_cloud_analog[0]''       | Enables writing analog values from Cloud to timetable: 1=enabled. |
| ''optimization_command[0..50]''     | cloud timetable optimization command: 1=set once action, 2=set recurring action, 3=set critical peak tariff, 4=set mask, 5=set analog. |
| ''optimization_value[0..50]''       | timetable optimization value (depends of command): -1=clear/clear critical peak tariff, 0=set off/lo tariff, 1=set on/hi tariff, 2=set critical peak tariff, -100..100 set setpoint, -32768=auto). |
| ''optimization_start[0..50]''       | cloud timetable optimization start time 'hhmmw': hh=hour, mm=minute, w=weekday (1..7, 1=monday). |
| ''optimization_index[0..50]''       | timetable optimization index (0..8): 0=broadcast, 1=first consumer timetable, 8=last consumer timetable. |
| ''optimization_time[0..50]''        | timetable optimization period [min.] (max 1440 minutes). |


Variable ''optimization_command'' triggers timetable manipulation process so make sure to set all other variables before. 

==== Use cases ====
<wrap hi>**SCE01**</wrap> **Set once action**\\
Consumer [3] has to be switched off on Wednesday at 16:45 and be in this state for 1 hour.
<code>
if ( timetable_cloud_once[3] ) {   // 4. consumer (idx=3)
  optimization_index[0] = 4;       // 4. consumer (idx=3)
  optimization_start[0] = 16453;   // hh=16, mm=45, w=3
  optimization_time[0] = 60;       // 1 hour
  optimization_value[0] = 0;       // set off
  optimization_command[0] = 1;     // set once action
};

// Result:
//                 ^xxx

<wrap hi>**SCE02**</wrap> **Set recurring action**\\
Consumer [7] has to be switched on every Monday@08:00 and switched off every Monday@21:00.
<code>
