node-red-contrib-tick

A Node-RED Tick node, for precise periodic messaging

Installation

Install node-red-contrib-tick using npm:

npm install --save node-red-contrib-tick

Usage

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 and msg.error.

• msg.payload is counter (increases by 1 every tick)
• msg.error is difference from desired tick time (in ms)
