output-Blinker
A subflow to send pulsing messages at a given interval to make something flash.
Configurable by setting environment variables in the node's settings.
Output toggle node to send alternating messages at a specified frequency.
3 things need to be set to configure this subflow
1 - delay: milliseconds between toggls
2 - msg1: text message for state 1
3 - msg2: text message for state 2
Optional:
offmsg - sent when it is reset.
May be handy to make sure things are off.
Input message
To start send msg.payload (anything)
To stop, send msg.reset (payload anything but please don't use timestamp)
Added:
msg.topic now also toggles between 1 and 2 to indicate which message is being sent.
