// Shelly Script example: Control a open or close a Shelly Plus 2PM (Gen2) on cover mode
// by handling specific events
//
// The script, when run, will subscribe to events and handle "cover_open_to" and
// "cover_close_to" events.
//
// The script requires the event data to specify the desired position and optionally
// the hours and minutes of the day which the event should not be executed before.
//
// Example event data:
// {
//   "pos": 100,
//   "not_before": {
//     "h": 8,
//     "m": 0
//   }
// }
//
// Note: Currently, "not_before" is only supported for "cover_open_to" events.
//
// The event can be published on a schedule as follows:
//
// {
//   "id": 8,
//   "enable": true,
//   "timespec": "@sunrise+00h00m * * MON,TUE,WED,THU,FRI",
//   "calls": [
//       {
//           "method": "script.eval",
//           "params": {
//               "id": 1,
//               "code": "Shelly.emitEvent(\"cover_open_to\",{\"pos\":60,\"not_before\":{\"h\":7,\"m\":30})"
//           }
//       }
//   ]
// }
//
// The above example will publish the event at sunrise, top open the cover to position 60, but not before 7:30 AM.
