node-red-contrib-chronos 1.25.6
Time-based Node-RED scheduling, repeating, queueing, routing, filtering and manipulating nodes
node-red-contrib-chronos
A collection of Node-RED nodes for date and time based scheduling, repeating, queueing, routing, filtering and manipulating. Automatically calculated times from sun events (sunrise, sunset, dusk, dawn, ...) or moon events (moonrise, moonset) are supported as well.
If you encountered a bug, would like to propose a new feature or simply want to share your opinion about the software, please have a look at the contribution guide on the GitHub repository to learn more about how to contribute to this project. If you need help or have questions, please check out the instructions for getting support.
To see what has changed in recent versions of the software, please have a look at the project's release notes.
Scheduler
Schedules the transmission of messages or setting of global/flow variables at specific times.
State
Maintains a state whose value is changed at specific times under consideration of specific conditions.
Repeat
Repeats each message passing through the node based on a configurable interval.
Delay
Delays each message passing through the node for a configurable amount of time or until a specific point in time is reached.
Time Switch
Routes messages based on a specific time.
Time Filter
Filters messages based on a specific time.
Time Change
Modifies time values in messages or context stores.
Documentation
Each node has a built-in help that is displayed in the help tab of the Node-RED sidebar providing essential information about how to use the node. There is also a comprehensive and detailed (English-only) documentation available in the wiki of the GitHub repository.

For the calculation of sun and moon position based times, the nodes make use of the great Node.js library SunCalc from Vladimir Agafonkin. The processing of cron based schedules is done via the Node.js library CronosJS and date and time algorithms are provided by the Node.js library Moment.js.
The map for showing the location coordinates in the configuration node is provided by OpenStreetMap.
