node-red-contrib-bayesian

A bayesian binary sensor node for Node-RED, similar to the one from Home Assistant.

The necessary values for configuration can be calculated using the spreadsheet found here.

Configuration

Property	Value	Description
Name	string	The name of the node.
Probability treshold	number	The probability at which the node should output true.
Prior	number	The prior probability of the event.
Observations	list of two numbers	Observations and their probabilities of occurring given the state of the observation is true/false.

Inputs and outputs

Input: The node expects an array of booleans as long as the observations list. Each boolean should correspond to the state of an observation. Missing values are treated as false, extra values are ignored.

Output: The node outputs either true or false depending on the observation states and probabilities.
