A Node-RED Tick node, for precise periodic messaging
node-red-contrib-tick using npm:
npm install --save node-red-contrib-tick
To use the node, launch Node-RED (see running Node-RED for help getting started).
Tick node emits message periodically in given interval. Message is emitted relative to system time. When
time mod interval = 0 is satisfy node ticks.
This is different from inject node in repeat mode which is relative to deploy (e. g. 1 second from deploy not when system time is exactly whole second).
Outputs message containing
- msg.payload is counter (increases by 1 every tick)
- msg.error is difference from desired tick time (in ms)
