Trigger a Flow at Regular Intervals
Problem
You want to trigger a flow at regular intervals. For example, to periodically call an API to retrieve its current state.
Solution
Use an Inject
node configured to repeat at the desired
interval.
Example
Flow JSON
[{"id":"372cfc32.bcd244","type":"inject","z":"535331d8.55c1f","name":"","topic":"","payload":"","payloadType":"date","repeat":"5","crontab":"","once":false,"x":150,"y":600,"wires":[["6c63c499.ce3adc"]]},{"id":"6c63c499.ce3adc","type":"debug","z":"535331d8.55c1f","name":"","active":true,"console":"false","complete":"false","x":410,"y":600,"wires":[]}]
Discussion
The Inject
node can be configured to repeat at a fixed
interval. If desired, it can also be constrained to do so between certain times on
certain days.
