node-red-contrib-boolean-logic-ultimate

A set of Node-RED enhanced boolean logic, with persisten values after reboot and more.

Wellcome! First of all thank you for your interest in my nodes. This is a set of logic nodes, to overcome the simplicity of the default node-red boolean logic nodes. Hope you enjoy that and if you're in trouble, please ask!

The node performs Boolean logic on the incoming payloads.
The node expects a fixed number of topics (configured in the settings) on which it will operate. It will only output a value when it has seen the expected number of topics. If it ever sees more than the configured number of topics it will log a message then reset its state and start over.
The input message is preserved and passed to the output pin, changing only the topic and the payload.

The node performs some checks on the incoming boolean payloads and outputs all results at the same time, as follow:

• Output "AND": true or false
  
• Output "OR": true or false
  
• Output "XOR": true or false
  

If you need "NAND" or "NOR" gate, just put an InvertUltimate node respectively after the "AND" or "OR" pin.

The node can have a persistent input: the input values are retained after a node-red reboot. That means, that if you reboot your node-red, you don't need to wait all inputs to arrive and initialize the node, before the node can output a payload.
You can also set the default values of the topic inputs.

CONFIGURATION

Inputs count

Set the number of different topics to be evaluated. The node will output a message to the flow, after this number of different topics arrives.
Remember: each input topic must be different. For example, if you set this field to 3, the node expects 3 different topics.

Filter output result

• Output both 'true' and 'false' results: Standard behaviour, the node will output true and false whenever it receives an input and calculate the boolean logics as output.
• Output only 'true' results: whenever the node receives an input, it outputs a payload true only if the result of the logic is true. False results are filtered out.

Trigger mode

• All topics: standard behaviour, the node will evaluate each input topic and ouputs the values. At each input change, it will output a msg on the flow.
• Single topic + eval other inputs: the node evaluates all the input topics, but only whenever it receives a msg input with the specified topic, it outputs a msg to the flow.

If input states are undefined

Every time you create a node or modify the node, all inputs are set to undefined. This means that the node will wait the arrive of all topics (for example 3 topics, if you've selected 3 topics in the option), before it can output a payload. This can be a problem if your logic must be operative as soon as you deploy the flow. To overcome this problem, you can "initialize" all the undefined inputs with True or False.

• Leave undefined: Standard behaviour, the node will wait all the "undefined" topics to arrive, then starts a flow with the result.
• True or False: The node is immediately operative, by force the initialization of the "undefined" inputs with "true" or "false".

Remember latest input values after reboot

If checked, the input values are retained after a node-red reboot. That means, that if you reboot your node-red, you don't need to wait all inputs to arrive and initialize the node, before the node can output a payload.
Every time you modify the node's config, the retained values are cleared.

INPUT MSG TO THE NODE

msg.reset = true; Resets all inputs to undefined.

INTERRUPT FLOWS ULTIMATE

Whenever this node receives a payload = false from a specific topic, it stops output messages to the flow. As soon it receives payload = true from this topic, the output messages start to flow out again.

In this other example, you can see the property "play" in action. This property allow you to replay the last previously stored message.
This allow to save the state of a node and then replay it back whenever you want.

INVERT ULTIMATE

Outputs the inverted input. For example true -> false
The input message is preserved and passed to the output pin, changing only the topic and the payload. If the input message has it's own topic, it'll be preserved as well.

FILTER ULTIMATE

This node has 2 outputs.
If the input payload is true, the node will send true on output 1 and nothing on oputput 2
If the input payload is false, the node will send nothing on output 1, and false on oputput 2
The input message is preserved and passed to the output pin, changing only the topic and the payload. If the input message has it's own topic, it'll be preserved as well.

BLINKER ULTIMATE

The pourpose of this node is to blink a led or something.
Output PIN1 : outputs the value true/false
Output PIN2 : outputs the inverted value false/true

Pass msg.payload = true to start blinking
Pass msg.payload = false to stop blinking
Pass msg.interval = 2000 to change the blinking interval

• PIN1 stop behavior : when the blinker receives the stop message, you can select the behavior of the pin1
  
• PIN2 stop behavior : when the blinker receives the stop message, you can select the behavior of the pin2

SIMPLE OUTPUT ULTIMATE

The pourpose of this node is to send a message with payload TRUE on the first pin and FALSE on second pin, independently from the msg input.
This is useful if you need to simply send a true or false payload.

INJECT ULTIMATE

The pourpose of this node is to send a message with payload TRUE on the first pin, FALSE on second pin and a TOGGLE (true/false) on the third pin, by pressing the pushbutton.
This is useful if you need to simply test your flow. The node is simpler as the default node-red inject node.
