node-red-contrib-cron-plus

A flexible scheduler (cron, solar events, simple dates) node for Node-RED with full dynamic control and Timezone support

QUICK DEMO...

FEATURES

• Schedule by CRON, date sequences and solar events (with offset)
  • A human readable description of your expression is provided as you type.
  • 
• Multiple schedules can be entered by the node editor UI or dynamically at runtime
• Send a default payload or any of the following: timestamp, string, number, boolean, flow variable, global variable, JSON, Buffer or Env variable as the output.
• Example CRON expressions provided in the dropdown to get you started
• Map popup to help you enter coordinates for solar events
  • NOTE: Map is 100% CDN dynamic and requires and internet connection. If there is no internet, the popup will provide information to help you get location coordinates from another source
  • 
• Option to separate command responses from output 1 to seperate 2nd output
• Settable output variable (normally msg.payload but it is up to you)
• Inject-like button to fire the node (available when only one schedule is added)
• View dynamically created schedules in the node editor UI
• Additional info about the triggered schedule is always send in the output message in msg.cronplus
  • NOTE: if the payload is to "Default Payload", then the content of msg.cronplus is moved to msg.payload
• Node status updates to show the next event
  • NOTE: the status indicator will be shown as a "ring" for dynamic schedules or shown as a "dot" for static schedules
• Full flexability & dynamic control.
  • Ability to control via simple topic commands. Examples include...
    • remove, remove-all, remove-all-dynamic, remove-all-static
    • list, list-all, list-all-dynamic, list-all-static
    • export, export-all, export-all-dynamic, export-all-static
    • stop, stop-all, stop-all-dynamic, stop-all-static
    • start, start-all, start-all-dynamic, start-all-static
    • pause, pause-all, pause-all-dynamic, pause-all-static
  • Ability to add, remove, list, export, stop, start, pause schedules by a command payload input. Examples include...
    • add - add one or more dynamic schedules
    • describe - describe solar events or cron expression (without the need to add a schedule)
      • useful for creating a dynamic dashboard like this
• Demo flows demonstrating many of the capabilities. Import via node-red menu > import > examples.
• Optional timezone setting suppoting UTC and Region/Area (e.g. Europe/London)
