- very stupid question and someone please eli 5

- what exactly do i need node red for?

Workflows that require flow logic.

I use NodeRed extensively with home assistant, here's an example of a flow:

My front door opens (trigger) > turns lights on, but then also: > wait 3 minutes > check if my or spouse's phone is pingable > if neither phones are pingable then turn off all lights, AC units, and enable house alarm

Also another flow that's uses daily: 8:30pm(trigger) > check which house lights are on > any light that is on trigger a gradual temperature shift to warm and brightness to 50% over 10 minutes

- interesting, how does it interface with hardware,

- is it a low level c API or something that has directly interface to communicate with arduino, raspberry etc?

- what kind of devices can you use it with?

		Not sure about those, I've only uses it with home assistant and virtual logic and communication. The most I use it when it comes to hardware is sending commands to my phones/tablets/laptops to run on/off, open urls, toggle wifi/Bluetooth, etc.
