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.
