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




    • Schedule by CRON, date sequences and solar events (with offset)
      • A human readable description of your expression is provided as you type.
      • cron-tt
      • An Easy Expression Builder to aid cron novices
      • easy-expr-builder
    • 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
      • cron-plus-map
    • Option to separate command responses from output 1 to separate 2nd output
    • Fan out option to separate each static schedule to its own output (dynamic and command responses are sent on last 2 output pins) (as of V1.4.0)
    • 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 sent 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 flexibility & dynamic control.
      • Ability to control via simple topic commands. Examples include...
        • remove, remove-all, remove-all-dynamic, remove-all-static, remove-active, remove-active-dynamic, remove-active-static, remove-inactive, remove-inactive-dynamic, remove-inactive-static
        • list, list-all, list-all-dynamic, list-all-static, list-active, list-active-dynamic, list-active-static, list-inactive, list-inactive-dynamic, list-inactive-static
        • export, export-all, export-all-dynamic, export-all-static, export-active, export-active-dynamic, export-active-static, export-inactive, export-inactive-dynamic, export-inactive-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)
    • Recognises system clock changes and recalculates schedules
    • Demo flows demonstrating many of the capabilities. Import via node-red menu > import > examples.
    • Optional timezone setting supporting UTC and Region/Area (e.g. Europe/London)


    • Easiest...

      Use the Manage Palette > Install option from the menu inside node-red

    • Harder...

      Alternatively in your Node-RED user directory, typically ~/.node-red, run Run the following command in the root directory of your Node-RED install. (Usually this is ~/.node-red or %userprofile%\.node-red).

      Install from GIT

      npm install Steve-Mcl/node-red-contrib-cron-plus

      Install from NPM

      npm install node-red-contrib-cron-plus

      Alternatively, install from a folder

      npm install c:/tempfolder/node-red-contrib-cron-plus

      Or simply copy the folder node-red-contrib-cron-plus into a folder named nodes inside your node-red folder then cd into nodes/node-red-contrib-cron-plus and execute npm install




    npm i node-red-contrib-cron-plus
