node-red-contrib-logical-nodes

Version: 0.5.1

Description

node-red-contrib-logical-nodes is a collection of logical nodes for Node-RED. This package includes logical AND, OR, NOT, Boolean, and Compare nodes that allow you to perform basic logical operations on incoming messages.

Nodes

AND Node

Performs a logical AND operation on the payloads from different topics. Outputs true only when all values are true.

• msgCount: The number of distinct topics required before the output is triggered.
• newMsg: Generates a new message with the result if set to true.
• topic: Specifies the topic for the output message.

OR Node

Performs a logical OR operation. Outputs true when at least one value is true.

• msgCount: The number of distinct topics required before the output is triggered.
• newMsg: Similar behavior as in AND Node.
• topic: Specifies the topic for the output message.

NOT Node

Inverts the boolean value of the incoming payload.

• newMsg: Generates a new message instead of modifying the existing one.
• topic: Specifies the topic for the output message.

Boolean Node

Routes the message to different outputs based on the boolean payload. If the payload is true, the message is routed to the first output; if false, to the second output.

• topic: Specifies the topic for the output message.

Compare Node

Evaluates a property from the incoming message and compares it to a value using a variety of operators (e.g., ==, !=, <, >, is true, is false, etc.).

• newMsg: Generates a new message with the result if set to true.
• topic: Specifies the topic for the output message.
• property: The property of the message to be compared (e.g., msg.payload).
• operator: The comparison operator. Available operators include ==, !=, >, <, >=, <=, is true, is false, is empty, is not empty.
• value: The value to compare against (for relevant operators).

Installation

Install this package directly within Node-RED using the Manage Palette option or via npm:
