node-red-node-random

A Node-RED node that when triggered generates a random number between two values.

Install

Run the following command in your Node-RED user directory - typically ~/.node-red

npm install node-red-node-random

Usage

A simple node to generate a random number when triggered.

If you return an integer it can include both the low and high values. min <= n <= max - so selecting 1 to 6 will return values 1,2,3,4,5 or 6.

If you return a floating point value it will be from the low value, up to, but not including the high value. min <= n < max - so selecting 1 to 6 will return values 1 <= n < 6 .

Note: This generates numbers.
