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 3 checks (AND,OR,XOR) on the incoming boolean payloads and outputs the result at the same time, as follow:
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.
Number of different topics to evaluate
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
Trigger mode
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.
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.
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.

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.
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.
