A simple node-red node that sends a message at regular intervals.
interval: the duration between calls
unit: the duration unit
name: simply rename your node
msg: the text to be sent as payload
onstart: Wether or not to send a message on start
showstatus: show the last and next trigger times
statusformat: A momentjs date format used to display status
{
"payload": "<config.msg>"
}You can import the following flow and use it to test and experiment with the node.
